PREFACE TO THIRD EDITION.
The Second Edition of this work being now out of print for some years it
has been suggested to me that I should re-write the Manual and bring it
up to date. It does not purport to be a highly technical work, but will,
I trust, indicate to those requiring fuller information where to look
for it. Two Chapters have been added on Road Making and Building
Construction which, it is hoped, will make the book more useful to those
for whom it is written. The arrangement of the Chapters has also been
altered.
My acknowledgments are again due to many friends who have helped me in
revising the Second Edition of this Manual.

INTRODUCTION.
A concise handbook dealing with the most important points of the
sanitation of Indian Bazaars is much needed; this is an endeavour to
supply the want and put the information available on the subject in a
convenient form, so as to facilitate the organization, and control the
working of the sanitary department of a municipality. It is not within
the scope of this work to allude to large waterworks or drainage
schemes, but merely to show how existing arrangements can be improved.
The real secret of sanitation is the prompt removal of fæcal matter and
refuse from the neighbourhood of inhabited buildings before it has time
to decay, as in the early stages of putrefaction emanations are evolved
which are highly dangerous to health; it is also an admitted fact that
the common fly is a considerable factor in disseminating disease, as it
conveys germs on the pads of its feet from infected matter to the
food-supply of the inhabitants.
My thanks are due to many who have been good enough to assist me in this
work, and especially to Lieutenant-Colonel Whitwell and Captain J. C.
Vaughan of the Indian Medical Service; to Mr. A. E. Silk, Sanitary
Engineer to the Government of Bengal; and to Captain D. Meagher, the
Officer in charge of the Government Farm at Allahabad.

PREFACE TO SECOND EDITION.
The First Edition of this work was favourably received and, being
entirely disposed of within five months of its issue, indicates that a
want was met. The Manual has been patronised by the Government of India,
the Secretary of State for the Colonies, the Local Governments of
Bengal, Madras, Burma, Punjab, the United Provinces of Agra and Oude,
Assam, the Central Provinces, the North-West Frontier Provinces,
Baluchistan, and other Administrations, as well as by several Native
States, and by the Nepal Durbar. A Second Edition with a good deal of
additional matter added, has therefore been prepared, but this has been
called for before the Author was ready for it, and estimated results
have in consequence been given in several instances instead of recorded
facts. The science of sanitation is, however, progressing so rapidly,
that a good deal of useful information is available, and advantage has
been taken of criticisms to amplify several points. Additional
information has been given on the Biological System of Disposal of
Sewage, on Markets, and Drain Flushing among other subjects, and
Appendices C to F have been added.
I take this opportunity of again thanking many who have assisted me, and
for the generous tone of the criticisms in the public press.

CHAPTER I.
SURFACE OR STORM-WATER DRAINAGE.
Owing to the fact that earth for the construction of most of the huts in
a bazaar has been excavated from the immediate vicinity of the
buildings, it is a matter of much consideration to determine the most
suitable levels the surface drains should start at, as it is of
importance that these should be as shallow as circumstances admit of in
order that they may obtain the full benefit of purification by sun and
air. By adopting as high a level as possible at the head of the drain it
enables better gradients, or falls, to be given which aids much in
self-cleansing. The greatest care should be taken not to lose, or waste
what little fall there is in the plains, as this is simply invaluable.
Deep drains rapidly become foul at the sides and bottom, are difficult
to flush owing to the quantity of water required to do so effectively,
and great temptation is also given to adjacent house-holders to bridge
them over with wide platforms, the consequence being that, sooner or
later, the storm-water drain, designed as an open one, and for which it
may originally have been more or less suitable, soon changes its
character, and becomes a badly designed sewer, which imprisons and
concentrates noxious effluvia. When a drain runs beneath a road,
provision should be made for a part of it being easily uncovered to
admit of examination and cleaning. All drains should open into others at
acute, and not at right angles, and must join at top to top, and not at
base level; where necessary the difference of level can be made up by
falls.
[Sidenote: Surface drainage of small roads.]
The surface drainage of small roads and paths in a bazaar is best
provided for by the construction of a central drain down the middle, to
which the ground is made to slightly slope from each side; this prevents
the accumulation of filth in the so-called side drains, which are
generally merely long pits; and, provided a slight fall be given, they
are self-cleaning at every shower of rain.
In paths or gullies a small concrete saucer drain can be constructed, at
a cost not exceeding four annas a lineal foot, into which the house
connections can be made,—the paths being paved with bricks, set flat,
not costing more than Rs. 2–8 per 100 square feet. These should be laid
at a good slope to the drain, and as only foot traffic need be provided
for, is amply strong enough. In many cases it will be found that
adjacent house-holders are quite willing to pay for this work, when once
a commencement is made, and the advantage is obvious to them.
[Sidenote: Kutcha roadside drains.]
In kutcha roadside drains care must be taken that, in the process of
cleaning, which generally consists in the removal of the bed, they do
not in time become permanent roadside trenches without fall; it is much
better to have no drains at all than this; mere depressions which, when
dry, can be swept, and which will be washed clean after a heavy shower
of rain, are much preferable. The proper bed-level of a kutcha drain
should be permanently marked by wooden pegs driven well into the earth,
and built into a masonry pillar, 1 foot 10 inches square, or by masonry
profiles, at intervals of 100 feet apart; this shows at once if the
bed-level or section has been unduly lowered during the process of
cleaning out.
[Sidenote: Flushing.]
When designing a drainage system for a town it is essential that
provision for flushing be made at the same time, otherwise the drains
become receptacles for filth for about two-thirds of the year. This can
be arranged by the construction of flushing tanks, which, when full
automatically discharge into the drains, by water mains laid underground
discharging into the head or summits of the drains; and also by the
drains being divided up into convenient sections by stops or sluices,
which are lifted automatically, or by manual labour, when the section is
full of water, thus ensuring an effective flush.
[Illustration:
FIG. 1.
AUTOMATIC FLUSHING TANK
]
A type design of an automatic flushing tank is shown in Fig. 1. These
cost about Rs. 100 each complete, the syphon pipe alone representing
some Rs. 30. Where sufficient head is not unavailable for this type,
Adams’ Patent Adamic Flusher may be suitable. These cost about Rs. 70
for a 4″ pipe size, and works with a head of 10 inches.
Where sullage water is discharged into storm-water drains this should be
treated in sullage filters at convenient intervals. _See_ Fig. 18, page
36.
[Sidenote: Masonry drains.]
The most suitable form for surface drains is the semi-circular base,
with side slopes of 1 to 2·4, as the discharge is only slightly less
than that of the ovoid section, and the drains are more easy to
construct. They can be easily swept clean, or run through with a wooden
board made to fit the section, and pushed along by a boy.
The Dacca type rectangular drain, as shown in Fig. 2, page 5, is very
suitable for narrow lanes. The dimensions can be altered to suit local
conditions.
Much useful information as to the preparation of drainage projects, and
tables of discharges of different sections, will be found in Practical
Instructions in Surface Drainage, by Mr. H. A. Gubbay, Executive
Engineer, Public Works Department, published by the Government of
Bengal.
In most cases, when designing a system of drainage, it is advisable
merely to take the general surface level of the bazaar as the level to
be drained, leaving artificially caused depressions to be filled up with
the débris of old buildings, and any available suitable material as
opportunity occurs. It is also generally unnecessary to provide for a
very heavy rainfall. The usual provision in this part of India is for a
run off due to ½ an inch of rainfall per hour from densely built over,
and ¼th of an inch from suburban areas.
It is more scientific to design the drains with reference to the
possible flushing power and facilities available, rather than that of
the maximum rainfall.
The importance of proper drainage, especially in connection with
checking the spread of malarial fever by anopheles mosquitoes has, owing
to recent researches, been fully recognised. These are found to breed
most extensively in the earth-lined drains alongside streets. Where
brick-lined, the current should be strong enough to wash away the larvæ,
but it is quite otherwise on the numerous kutcha ones in every bazaar.
It is also essential, in Bengal, to make use of the powers conferred by
the Municipal Act (Section 195) to compel owners to fill up small
depressions which, during the rains, form extensive and numerous
breeding-grounds. Every attempt should be made each year to brick-line a
section of the roadside drains as money is available, where funds do not
admit of much being done. Grass and weeds in the earthen drains must be
cleared out at regular intervals during the rains, and the oftener the
better. Mosquitoes of the culex tribe cannot also be disregarded, as
these have been proved to convey elephantiasis and other diseases, and
stegomyia, which abound in Lower Bengal, are the hosts of yellow fever.

CHAPTER II.
WATER-SUPPLY FROM WELLS AND TANKS.
[Sidenote: Registering wells.]
[Sidenote: Cleaning and repairing wells.]
In order to obtain a comparatively pure water-supply, under
circumstances existent in most bazaars, it is essential that the spill
water from wells be led away by properly constructed drains beyond what
is known as the cone of filtration; this may be described as a circle
drawn round the mouth of the well, the radius being equal to the depth
of it. Owing to Indian customs, there is always a considerable quantity
of spill water in the vicinity of a well, and this, when proper
platforms and drains are not constructed, finds its way back, after
contamination, by the line of least resistance, either down the sides of
the masonry lining, or by cracks and fissures in the ground. For water
supplies from wells and tanks the main object is to prevent any water
once drawn out, again, after probable contamination, flowing back into
the source of supply. Arrangements should be made for registering every
well in a municipality where this has not already been done, and for
taking over, or closing all those the owners refuse, or fail to put in a
proper sanitary state. In Bengal this can be enforced under section 200
of the Bengal Municipal Act (1894). A copy of the map of a ward showing
the position of all wells and tanks therein is given in Fig. 3. The Well
Register, which should be corrected yearly, is given in Appendix C, page
62. It is impossible in most cases, owing to large numbers, for a
Municipality to take over, repair, and conserve all the wells (in the
town of Muzaffarpur, there were 718 wells) but much good can be done by
acquiring a certain number of the most useful unowned ones, and making
the owners of others, when in a position to do so, put and maintain them
in a sanitary state. When new wells are sunk, the owner must be made to
construct them according to a standard design. Fig. 4 shows an
inexpensive and good form of open well, top, and platform. From the
experience of ten years in the Muzaffarpur District (from 1891 to 1901),
where wells on the sides of main roads were so treated, this is
possible. Some 400 wells on 725 miles of road were taken over by the
District Board, put in a proper state of repair, suitable platforms and
spill-water drains constructed, and arrangements made for annual
cleaning out and disinfecting with permanganate of potash during the hot
weather months. These were eventually greatly appreciated, and, whereas
in the first instance difficulties were experienced in getting hold of
suitable ones, it was of late years necessary to make careful selections
from the applications received. In addition to this, the owners of
numerous ones, on whom notice was served that if they did not put them
in a sanitary condition, they would be taken over and repaired by the
District Board, elected to do the work on the prescribed lines at their
own expense. It is a notable fact that cholera when prevalent in
villages close by, frequently is not found in those where these wells
are situated. This organization is being extended to villages which have
an especially bad sanitary record. For easy reference the Instructions
for Repairing, Cleaning and Disinfecting Wells are quoted.
[Illustration:

WARD Nº 11
FIG. 3.
]
_Repairing._
1. The ground round a well must first be excavated to a depth of at
least 5 feet below surface level, and for a width of 5 feet round the
well and sealed with puddled clay, the well lining being first rebuilt
from this level where necessary, and continued up for a height of 2 feet
6 inches above ground-level; the top of the well must be sloped off to
prevent vessels being placed on it, and consequent splashing getting
back into the well. A properly made platform resting on suitable
foundations, must be built round the well at 1 foot above at its highest
point, and sloping off to ground-level at its lowest, with a ridge round
it to prevent spill-water draining away indiscriminately and an opening
at its lowest point, leading into a pucca drain, constructed with a
suitable fall, and continued until natural drainage is reached, or
outside the cone of filtration, so as to prevent any water lodging in
the vicinity of the well.
2. A closed-in top prevents dust, which may convey pathogenic germs,
gaining access to the water.
_Cleaning._
3. Wells should be dewatered, and cleaned out at least once every year.
The sides must be scraped, and all mud, broken earthen vessels, etc.,
removed; _quicklime_ must then be applied to the sides and bottom of the
wells.
4. The only suitable time to clean out wells is during the hot weather
as the water in them is then at its lowest level.
5. All wells must be cleaned out down to the well-curb or “Jamot.”
_Disinfecting._
6. Permanganate of potassium is a crystalline salt-like substance of a
purple colour, in the preparation of which only mineral substances are
employed.
[Illustration:
FIG. 4.
Well Top
]
[Illustration:
FIG. 5.
]
[Illustration:
FIG. 6.
]
7. Put one or two ounces of the solid substance into a _dol_, or bucket,
which has been filled with water drawn from the well about to be
treated. Stir it up, and pour the red solution thus produced into the
well, leaving the portion of permanganate that is not yet dissolved at
the bottom of the _dol_. Lower the _dol_ into the well, fill it with
water, draw it up, pour back the water as before, and repeat the process
till all the permanganate has been dissolved. In all cases enough
permanganate should be added to produce a faint red colour lasting for
24 hours.
8. If the water in the well is bad, more permanganate will be necessary.
In such a case it will be found that the strong red colour at first
produced quickly changes to brown, and then fades away. This is because
the permanganate destroys dirt and is destroyed by it. Therefore, if the
water in the well is clean, a smaller quantity of permanganate will be
necessary. From one to four ounces of permanganate will be found to be
enough for ordinary wells. If more permanganate is added than is enough
to produce a faint permanent red colour, it is likely that frogs, that
may be in the well, will be killed. This will, in a few days, give the
water a putrid taste. If the quantity of permanganate is not enough to
produce a faint permanent red colour, it is unlikely to do good. If
possible, the permanganate should be added at night, in order to leave
the wells undisturbed as long as possible. The water will be fit to
drink on the following morning. If then a red colour is still present,
the water may have an unpleasant taste, but it is perfectly harmless.
Figure 4 is an illustration of the latest pattern of well adopted.
[Sidenote: New Wells.]
When a new well is proposed, and local conditions are suitable, a safe
form is that designed by Dr. Cameron of Wigton, N. B. This arrangement
is shown in Fig. 5. The well should be in the centre of a reserved area
of at least 20 yards in diameter, and the lead pipe leading from it to
the pump must be fitted by brass screw joinings. This is a suitable
design for the vicinity of cutcherries, where an open space for a
reserved area is generally available.
Another excellent design for a new well, and one more generally
suitable, is shown in Fig. 6. This prevents any danger of the water
being contaminated by dirty vessels being lowered into it for the
purpose of drawing water.
[Illustration:
FIG. 7.
]
[Sidenote: Tube Wells.]
Tube wells answer admirably in many localities; it is, however, always
essential to have a bore hole made first to determine the stratum which
has to be tapped, as the point of the tube may be easily driven through
this. An improved form of pump is shown in Fig. 7; this obviates the
danger of impure water being put in the mouth of the pitcher spout pump
in order to make it draw.
The great advantage of tube wells is that they enable a stratum,
underlying that of impermeable stiff clay which exists in many cases, to
be tapped, thus avoiding the danger of contamination by subsoil water.
The supply from a tube well is, however, limited in quantity.
Where wells are founded on a clay stratum their efficiency can generally
be largely increased at a trifling cost, by driving a pipe lined boring
down until water-borne sand is met. Great care must, however, be taken
that, when the boring is going on, this stratum be not passed through,
and constant tests of the discharge obtained at the various depths are
therefore necessary.
[Sidenote: Water drawing utensils.]
In all cases it is advisable either to provide a pump on a public well,
or iron buckets with light chains and wooden pullies, so that private
water drawing vessels be not lowered into the water. The pump should be
fixed on the platform surrounding the well, and not on the top. A light
corrugated iron roof over the mouth of a well is also useful in
preventing leaves, and other impurities falling in, and also in
affording shelter to the water-drawers.
[Illustration:
PLAN OF DOME FOR WELL
FIG. 8.
]
An effective and economical well cover designed for Ranchi is shown in
Fig. 8, page 11. This, for a 8′ diameter well, costs about Rs. 90.
[Sidenote: Tanks.]
A large proportion of the water-supply of a Municipality is usually
taken from tanks, into most of which the drainage water from the
neighbouring vicinity is washed during the rainy season. This can be
prevented by raising the banks. The sullage water of a bazaar is
indescribably filthy, and if in-drainage is prevented the tanks will
fill up by percolation as the level of the subsoil water rises—a bad
enough source of supply, but infinitely purer than the surface water
combined with filth from a crowded area. The excavation of new tanks in
a Municipality should be discouraged as much as possible, and attention
paid to conserving the existing ones. Small pumps and masonry platforms
for washing purposes draining away from the tanks will improve matters.
In the late Mr. A. E. Silk’s book on “Municipal Engineering in Bengal”
the following classification of comparative purity of water-supply is
adopted:—
1. Deep spring water.
2. Subterranean or deep well water.
3. Upland surface water.
4. Subsoil water. (If distant from any collection of houses).
5. Land springs.
6. River water.
7. Surface water from cultivated land.
8. Subsoil water under villages or towns.
Surface water from a bazaar is classified as sullage.
[Illustration:
FIG. 9.
]
Where tanks are used as a source of drinking water-supply, they should
be properly fenced and conserved, and the water drawn by a pump. Recent
researches have proved that polluted water, if stored in a tank or
reservoir where it can be preserved from subsequent contamination,
rapidly becomes pure. The Type plan, approved by the Sanitary Board of
Behar and Orissa, is shown in Fig. 9, page 13. This for an existing tank
of 100 yards square area is estimated to cost Rs. 2,700. The pumps,
provided in duplicate, are Kite double action pattern and cost about Rs.
425 each. The fencing provided is the Ideal Woven wire fence, 10
strands, 48″ high, and can be fixed at about 12 annas per yard.
Another and a cheaper method is shown in Fig. 10, page 15. Here the tank
is completely fenced in with the exception of an entrance to a platform
which extends towards the centre of the tank from which the water can be
drawn by hand. Model rules for clearing out and re-excavating tanks are
as follows:—
[Sidenote: Excavation.]
1. Tanks should be cleared out and re-excavated during the dry weather
months when the level of the subsoil water is at its lowest. Work should
be commenced in January or February and completed before the middle of
May, but these dates must depend more or less on the locality, as in
some parts of the Province the prevalence of heavy thunderstorms in May
might make it advisable to complete the work before then.
2. The re-excavation, until water-level is reached, should be carried
out in regular layers of 1 foot in depth, an offset of 1 foot being left
on the bank side for each layer. This, when dressed off, will give a
regular side slope of 1 to 1 to the tank. When water-level is reached,
if it be considered necessary to excavate below this, and if pumping
machinery to dewater the tank is unavailable, the area must be divided
up into compartments of suitable size, separated by bunds, one, or more
of which, can be dewatered by bailing into the adjacent ones, when the
excavation can be continued to the required depth, the other
compartments being similarly treated in turn.
[Illustration:
TYPE DESIGN FOR FENCING IN TANKS
FIG. 10.
]
[Sidenote: Disposal of Spoil.]
3. The spoil from the excavations should be placed on the outside of the
embankment formed round the tank when originally made, and should be
deposited in such a position to preclude, as far as possible, its being
washed back again by rain water.
[Sidenote: Dressing and Turfing.]
The crest of the embankment should be dressed off to a slope of 1 in 12
away from the tank, with side slopes on the outside of 2 to 1. This will
prevent direct contamination of the tank by spill water from the crest,
where persons or carts, may have encamped.
All slopes should be neatly dressed off; all those above highest
water-level being turfed during the commencement of the ensuing rainy
season. This is very important as it prevents the chance of a
considerable quantity of the excavated earth being washed back into the
tank.
Water-supply for Municipal and Rural areas is a subject which is, at the
present day, receiving much attention. It is being encouraged by
contributions from Government and from Local Authorities, by gifts from
wealthy Indian gentlemen, and by loans from Government redeemable in a
fixed period. For rules for the preparation of projects in the Province
of Behar and Orissa see Appendix F, page 69, and for the table of
instalments for the repayment of loans, Appendix E, page 68. The
comparative death-rate from Cholera and Intestinal diseases in
Municipalities which possess a pipe water-supply, and those without,
need only be glanced at to prove the vital importance of a pure
water-supply, and even these figures do not adequately indicate the true
position, as further loss of life due to water-borne diseases, cannot be
traced out from the statistics published. Major S. A. Harris, I.M.S.,
Sanitary Commissioner, United Provinces, in his paper on the effect of a
pipe water-supply on the reduction of Cholera in urban areas, read at
the Second All-India Sanitary Conference at Madras, in November 1912,
quotes the reduction of death-rate per mille before and after the
provision of a pipe water-supply for the following places:—
Before. After.
Dehra Dun 10·19 2·25
Meerut 7·49 3·02
Naini Tâl 10·19 2·86
and stated that the number of years in which the Cholera death-rate rose
above 1 per mille is seen to have been reduced by the filtered
water-supply to about ½ in Dehra Dun, Meerut, Benares, Lucknow and Naini
Tâl.
The cost of Water Works must vary considerably according to local
conditions. Where the supply is derived from a source not liable to
contamination, from spring wells, tube wells and infiltration galleries,
where subsequent filtration is unnecessary, the capital expenditure may
vary from Rs. 3 per head for a tube well, Rs. 4–8 from an infiltration
gallery supply, such as Congeeveram (Madras), to Rs. 10 and over for a
filtered water-supply derived from a river. The cost of the distribution
system must necessarily vary according to its size, and the density of
population in the area served, but this, under normal circumstances, may
be assumed at 50 per cent. of that of the Water Works. As each Province
in India has a Sanitary Engineer, and as the subject of the preparation
of a Water Works project is a highly technical one, it is beyond the
scope of this work to go further than to impress its importance. Any
efficient Water Works started means a large saving of human life and of
much misery.
CHAPTER III.
ROAD MAKING.
One of the most important points towards obtaining a good metalled road
is to ensure a proper foundation for the metal to be consolidated on,
and to see that the sides are well confined or tied in. Where bricks are
used for this foundation they should be whole ones, not bats, be tightly
packed together and then rammed with a wooden rammer. The edging should
consist of bricks-on-end well backed up with earth on the out, or berm
side. The same applies where stone is used for the soling. These must
have flat surfaces, be of fair size, and be well hand-packed together
and rammed. It is not much use doing metalling work on a raised road
until the embankment has at least 2 rains over it to properly
consolidate it. This equally applies to the approaches to bridges on a
kutcha road where the metalled portion should be extended to a length of
at least 10 feet beyond the toe of the approach slope.
[Sidenote: Stone Metal.]
In most municipalities it is financially impossible to thoroughly repair
all the roads each year, nor is it necessary to do so, if the work has
been properly done. A system of biennial or triennial repairs should
therefore be evolved. A diagram showing how this can be arranged is
shown in Fig. 11, page 19.
In the selection of stone metal it is of great importance to see that
stone of equal grade and hardness is used, and that surface, or
weathered rock, is not mixed up with the harder material lying
underneath it in the quarries. The stone should be broken to the size
that the largest piece shall pass freely through a 1½″ diameter ring.
When repairing existing metalled roads it is essential that all old
metal be picked up, and any rounded, or traffic-worn portions re-broken,
as it is impossible to ensure good consolidation unless the edges and
corners of the stone metal be sharp. Consolidation should be done by a
heavy roller. A steam roller for preference. The cost of a 6–ton steam
roller is about Rs. 6,000 and the working cost about Rs. 4 per day, but
this must necessarily vary considerably in different localities,
depending on the cost of fuel and labour.
[Illustration:
DIAGRAM
FIG. 11.
]
_For Oiling Roads._
[Sidenote: Oiling Roads.]
The roadway must first be swept clear of dust and foreign material, when
the mixture composed of one part of coal-tar to 20 parts of oil (liquid
fuel), mixed cold, must be sprinkled on through a watering cart. Men
with hard long handled brushes follow the cart, and brush the mixture
into the roadway, and repeat this operation for the second time in the
reverse direction, when ¼ of a mile has been done. The oiling lasts for
about 2 months, and costs about Re. 1 per hundred square feet.
[Sidenote: Tar-Macadam.]
Although tar-Macadam may be somewhat ambitious for mofussil
municipalities, an abstract of the specification for MacCabe’s
tar-Macadam, which was kindly supplied to me by the Chief Engineer of
the Calcutta Corporation, is of interest, see specification Appendix H,
page 75. The cost of a road so laid is Rs. 2–2–0 per square yard, and
although sufficient experience is not available to predict its life,
some has been down for 3 years and is still good. The materials consist
of two parts Pakoor Stone metal, MacCabe’s patent Bituminous binder of
Gas Co.’s Coal-tar, and Stagg brand English coal-pitch, in the
proportion of 1 of tar to 3 of pitch by weight, with stone chipping, and
sand as a top binder.
[Sidenote: Kunkar Metal.]
All _kunkar_ metal required for metalling or repair work should be
collected, screened, and stacked by the middle of May at latest;
screening must be done in the dry weather, otherwise the meshes of the
screen soon clog up when the _kunkar_ is damp, and the operation is more
or less a farce. A specification for this is given below:—
(1) All _kunkar_ must be washed, cleaned, and screened during the dry
weather months; and must be of such quality that, being re-washed and
rescreened through an expanded metal screen of ⅜″ mesh, set at an angle
of 45°, shall leave a residue of 80 per cent. pure _kunkar_. If _kunkar_
of a lower standard is stacked it must either be rejected, or the cost
of bringing the metal up to specification, deducted from the price paid.
(2) No _kunkar_ should be measured after the 1st June. All _kunkar_
collection must be completed by 15th May.
[Sidenote: Brick Metal.]
Brick metalled roads are rarely successful owing to the difficulty of
ensuring that the metal is of equal hardness throughout, and especially
so in a dry climate, as under heavy traffic the metal soon wears into
brick dust, which either blows away in the dry season in the form of
dust, or is washed away in the rains; on no account should _jhama_, or
vitrified brick, and red brick metal be mixed, as their degree of
hardness is so different.
[Sidenote: Morhum & Kutcha Roads.]
It is of great importance that excessive slope be not given in morhum or
kutcha roads, otherwise they will rapidly gutter during heavy rain. A
rise of 1 in 50 to the centre of the road will generally be found to be
ample.
[Sidenote: Stacking Metal.]
In order to control the collection of material it is essential that all
be stacked to gauge, or in boxes, and that the stacks be of equal size,
thus facilitating measurements.
[Sidenote: Consolidation of Metal.]
Consolidation of metal must invariably be done as soon after the rainy
season sets in as possible, and especially so for _kunkar_. Any heavy
rainfall in a water-bound road after the metal is once laid is
invaluable in helping consolidation, as it fills up all the interstices
which may be left after rolling or ramming; _kunkar_ should be
consolidated by ramming with heavy wooden rammers, although on a new
road a roller will be of use in forcing the _kunkar_ in between the
joints of the soling bricks, and jamming them into the earth, thus
making a solid foundation. A plentiful supply of water should be used in
the process of consolidation; this is most essential. Stone and brick
metalling should be consolidated by heavy rollers, a minimum quantity of
surfacing material being used. It is of great importance to keep the
berms well made up against the metalled portion of a road, otherwise the
metal will rapidly spread out under traffic.
In all cases it is of the greatest importance that the natural aid
afforded by climatic conditions be utilised in making roads; this is a
subject the importance of which is frequently overlooked. When the
consolidation of metal is seen to be going on after the end of the
rains, unless there are exceptional circumstances to justify this, the
official in charge may be condemned at sight as being ignorant or
incompetent.
Long lengths of road should not be taken up for repairs at a time, as
this causes much inconvenience to traffic. A furlong is the uttermost
limit admissible.
CHAPTER IV.
BUILDING CONSTRUCTION.
[Sidenote: Materials.]
[Sidenote: Kunkar Lime.]
_Kunkar_ lime should be burnt near the site of works from clean _kunkar_
with coal or charcoal. When the burnt _kunkar_ is taken out of the kiln
it must not be slaked, but after any clinker has been removed, should be
ground fine enough to pass through a screen of 400 meshes to the square
inch, and must be used freshly ground. It should contain over 40 per
cent. of Oxide of Calcium.
[Sidenote: Stone Lime.]
Stone lime should be obtained unslaked. Before being used it must be
slaked and sifted through a screen of 400 meshes to the square inch.
[Sidenote: Lime Mortar.]
Lime mortar to consist of fresh lime mixed by measure with sand or
_soorki_ in one of the following proportions, as may be directed:—
(_a_) 1 _Kunkar_ lime.
2 _Soorki_.
(_b_) 1 _Kunkar_ lime.
1 _Soorki_.
1 Sand.
(_c_) 1 _Kunkar_ lime.
2 Sand.
(_d_) 1 Stone lime.
2 _Soorki_.
2 Sand.
(_e_) 1 Stone lime.
3 _Soorki_.
1 Sand.
(_f_) 1 Stone lime.
4 _Soorki_.
(_g_) should not be used in the dry season as it sets too quickly.
The materials should be spread in layers not exceeding 3 inches in
thickness, and then incorporated in a steam mortar mill, or bylechuki,
with sufficient water to make it into a stiff paste. Mortar which has
once commenced to set should on no account be used in any work.
_Kunkar_ or Hydraulic lime must invariably be used for waterworks and
for wet foundations.
[Sidenote: Soorki.]
_Soorki_ must be made from well burnt brick-bats, and must pass through
a sieve of 1⁄16 × 1⁄16 mesh. Freshly burnt bats must only be used.
[Sidenote: Sand.]
Sand must be clean, sharp, and free from dirt.
[Sidenote: Khoa.]
_Khoa_ must be broken from thoroughly burnt bricks to pass through a
ring of 1½″ diameter.
[Sidenote: Cement.]
Portland cement must be of the best quality of English manufacture and
comply with the standard tests.
[Sidenote: Cement Plaster.]
Cement plaster to be made of one part of Portland cement to two parts of
sand, and must be properly mixed and applied fresh, the thickness of
each layer to be ½″ finished. The surface must be kept covered with wet
bags or straw for at least three days, after it has been completed.
[Sidenote: Bricks.]
Bricks must be hard, well burnt, sound, true to shape and size, and free
from flaws and other imperfections, and to be of approved sample.
[Sidenote: Brick-Work.]
Bricks must be laid true to line and level, with joints not exceeding ⅜″
in thickness, and of approved bond. They must be soaked in water for at
least four hours before being used. All joints must be raked out to a
depth of ½″, while the mortar is fresh.
[Sidenote: Pointing.]
All joints to be at least ½″ in depth, and thoroughly cleaned out by
watering and rubbing with a brush. Mortar for pointing to be composed of
one part of lime and one part of _soorki_, ground very fine in a mill,
or strained through coarse cloth. Flush pointing to be lined off true
horizontally and vertically with a string, the lines thus made to be
deepened by a rule made for the purpose.
[Sidenote: Culverts.]
The type of culverts adopted must be dependent on the depth of the drain
below the surface of the road. Where arching can be done it is
preferable. Where impracticable, the top should be covered with stone
slabs. Parapets should be provided with stone copings. All culverts on a
road or street should be numbered, and registered in the form given in
Appendix G, page 74.
The system of quadrennial repairs to bridges and culverts is an
essential towards efficient administration, and when once successfully
introduced, is economical.
In masonry buildings a damp-proof course, which may be made with either
asphalte, or with a layer of Portland cement 1″ in thickness, laid at
the top of the plinth, and just above floor-level, is most desirable in
order to prevent damp rising in the walls, if for no other reason than
that it prevents damage to the masonry, and to the plastering, or
pointing.
CHAPTER V.
LATRINES AND URINALS.
In dealing with the sanitation of a bazaar, the provision of
scientifically designed latrines and urinals is a matter of the greatest
importance. There are numerous patterns of these, some very well
arranged as regards the necessary requirements for efficient working,
but many more not so. The selection of the pattern adopted is frequently
a mere matter of chance, and the attention paid to the subject by the
Municipal Commissioners a minimum quantity; badly arranged ones are
probably just as expensive to construct in the first instance as good
ones, which are much more useful.
[Sidenote: Distribution of Latrines and Urinals.]
[Sidenote: Ventilation.]
[Sidenote: Drainage.]
A large number of small latrines and urinals suitably distributed are
more effective than a few large ones, and are not much more costly to
construct and maintain; they should not be grouped together, or placed
back to back, as light and air should be allowed to play on all sides;
for convenience a small covered annexe may be provided for the carts.
For ventilation purposes it must be remembered that, owing to the
friction of the air on the sides, a number of small openings are not
nearly of as great value as a large one of the same area. Where good
drainage is unavailable, storm-water from the roofs should discharge
into moveable buckets which can be easily emptied, thus avoiding
saturation of the soil. Care must however be taken to put these in
places where they cannot be misused.
[Sidenote: Latrines at Police Barracks and private houses.]
Latrines should be provided at all Police barracks or out-posts; the
prevention of nuisance in a Municipality is under the control of the
local police, and the out-posts are, in many cases, either unprovided
with latrines, or have them of such a description that the men are
driven to commit the nuisance they are supposed to prevent. Similarly,
house-owners should be made to provide suitable arrangements for their
servants.
[Sidenote: Bailey’s Patent Latrines.]
A good latrine in the Indian market is ‘Bailey’s Patent,’ Fig. 12, page
27. This combines efficient ventilation of the latrine, with an
arrangement of double trays, thus preventing saturation and consequent
pollution of the soil on which it stands. The superstructure is made of
corrugated iron strongly braced, and can be made of any number of
compartments required; the patent latrine seat inside is independent of
the superstructure, and can be easily taken out and cleaned. The seats
however are inconveniently small. They cost from Rs. 114 for a two-seat
to Rs. 324 for an eight-seat one.
[Sidenote: Donaldson’s Separation Latrine.]
Donaldson’s Separation Latrine, in which the urine and solid matter are
kept separate, is also an excellent pattern. Separation latrines are,
however, unsuitable where it is proposed to deal with the night-soil by
bacteriological agency, and must seriously decrease its manurial value
also. It is merely a handy way of disposing of solid fæces.
[Sidenote: Alipore Pattern Latrine.]
The Alipore pattern latrine is a good type. Stoneware seats set in
brick-work are preferable to iron ones.
Septic tank latrines are very useful under suitable circumstances. A
design for a 12–seated one with a separate flushing tank for each seat
is shown in Fig. 13, page 28, the estimated cost being Rs. 4,586, or Rs.
382 per seat. Before deciding on adopting a latrine of this description,
“Sewage Disposal in the Tropics,” by Major Clemesha, I.M.S., Sanitary
Commissioner, Bengal, should be consulted.

[Sidenote: Masonry Latrines.]
[Sidenote: Disadvantages of Tarring.]
Where masonry latrines or urinals are provided, the walls and floor
should be smooth and well polished to allow of easy cleaning, and should
be white or some light colour, so that if there is dirt, it can be at
once seen and removed. In latrines for hospitals, and also in public
ones which are much frequented, it would be an advantage to line the
walls to a height of 3 feet, and also the floors, with glazed tiles or
bricks. This will make them much cleaner and less forbidding looking. It
is an obvious mistake to coat the lower part of a latrine wall with tar,
the antiseptic value of which, especially in a hot climate, is soon
lost, and which hides and retains dirt in its composition. The usual
practice is to cover a dirty latrine wall with a fresh layer of tar,
thus preserving an old coat of filth and forming a fresh bed for a new
one.
In all latrines it is of great importance to have the rear openings of
convenient size for the efficient removal of the buckets from their
seats on the level platform.
[Sidenote: Urinals.]
A cart urinal in the vicinity of cutcherries will be found useful. This
is merely a receptacle of convenient size resting on a masonry floor and
placed under a raised and enclosed platform on which the squatting plate
is fixed; the receptacle can be easily removed and replaced by an empty
one; the form is a convenient one and can be efficiently ventilated.
[Sidenote: Hindu Patent Urinal.]
[Sidenote: Disinfectants.]
Bailey’s Patent Urinal, Fig. 14, page 30, is very suitable. This costs
from Rs. 48 for a two-seat to Rs. 222 for a six-seat one. The patent
urinal stands inside the compartment and can be taken out and cleaned
without difficulty. For disinfecting purposes chlorinated lime is very
useful. It should have 33% of free chlorine, and must be used fresh as
it rapidly decomposes. Phenyle is also very useful.
[Sidenote: Red Hand Marks.]
An ingenious way of making Hindus face the right way, when using
latrines, is to make the mark of an outspread hand in red on the wall
which they should face, as no Hindu will turn his back on this sign.
[Sidenote: Model Rules.]
A set of model rules for private privies and urinals is given in
Appendix A, page 57.

CHAPTER VI.
COLLECTION AND REMOVAL OF NIGHT-SOIL.
In mofussil towns in Bengal the night-soil is generally collected from
public and private latrines by conservancy carts drawn by bullocks, and
varying in capacity from 60 to 200 gallons. These, as a rule, begin work
early in the morning so as to avoid causing a nuisance in the
thoroughfares, travel at a very low rate of speed, not over 2 miles an
hour, and only make one trip a day, in the majority of cases, owing to
the distance the trenching grounds are away from the centre of the town.
This means that a large proportion of the human excreta remains at least
24 hours in the receptacles of the latrines in the immediate vicinity of
densely populated localities. In the temperate climate of England it is
accepted as an axiom that sewage should never be more than 24 hours in
finding its way to the outfall, as it is, when it has begun to
decompose, more dangerous than when fresh and decomposition sets in much
more quickly in the semi-tropical climate of Bengal. In many cases the
quantity of night-soil collected per head per diem is exceedingly small;
the average amount of solid matter evacuated by natives may be taken at
10 ounces, and of urine 30 ounces, whereas returns from several
municipalities show a quantity varying from ·047 to ·37 of a gallon
removed by the conservancy carts. These quantities are, however,
calculated on the entire area of the municipalities, including the
suburbs, where, owing to the custom of Indians, the gardens and adjacent
fields dispose of a large quantity. In order to obtain reliable results,
the densely crowded areas should be divided up into blocks or sections,
keeping the figures well separated in the municipal books, the density
of population per block calculated and the quantity of night-soil
removed registered daily. Many of the Indian bazaars are long narrow
ones, situated on a high ridge of ground, in which case it is desirable
to have several trenching grounds, one for each block or group of
blocks, instead of having one large one situated at a considerable
distance from the centre of the town.
[Illustration:
FIG. 15.—CRAWLEY’S PATENT NIGHT-SOIL CART.
]
[Illustration:
FIG. 16.—RECEPTACLE CARTS.
]
[Sidenote: Conservancy Carts.]
[Sidenote: Receptacle Carts.]
In order to effect the speedy removal of fæcal matter, the provision of
suitable conservancy carts is of vital importance. Fig. 15, page 32, is
an illustration of Crawley’s Patent Night-Soil Cart, and is a good one
for general purposes. It is made entirely of wrought iron, with an
air-tight door for filling and emptying; the latter is done by releasing
a clip from the front of the barrel which connects it to the shafts and
opening the lid, when the barrel turns on its centre and shoots out the
contents. A 75–gallon capacity cart costs Rs. 130; a 110–gallon, Rs.
160; and a 200–gallon one Rs. 225. Small carts are preferable to large
ones, as they take a shorter time to fill, and therefore tend to the
more speedy removal of night-soil from crowded localities. They are also
more easy to handle at the trenching grounds.
It will sometimes be found advisable to provide receptacle carts for
removing receptacles from latrines. Fig. 16, page 33, shows this
arrangement. These, however, owing to their weight, and to the
difficulties of placing and removing the receptacles when full cannot,
excepting under special conditions, be recommended for municipal
purposes. They cost, including 12–gallon receptacles, about Rs. 275.
Each latrine must be provided with a receptacle, into which the buckets
are emptied, this being placed in a convenient position at the back of
the latrine; the cart starts on its rounds with six empty receptacles,
visits the latrines where it picks up the full ones, and replaces them
by clean ones. They are supplied in 6, 12 and 24–gallon sizes to suit
requirements, and the arrangement avoids the nuisance of transferring
the contents to a second utensil.
[Illustration:
FIG. 17.—NIGHT-SOIL RECEPTACLES AND HAND TRUCKS.
]
[Sidenote: Hand Carts.]
Hand carts are necessary in order to remove night-soil from houses built
in narrow lanes and places where it is impossible to get bullock carts
into. Fig. 17, page 34, shows a convenient arrangement for this. The
receptacles vary in size from 12 to 33–gallons, and cost from Rs. 37 to
Rs. 68 each; the bodies are detached from the hand truck by simply
raising the handles and disengaging the two-forked bearings with the
trunnion; they are fitted with a hinged lid and are made of strong
galvanized iron; the hand truck is of strong and light design, the whole
being of wrought iron.
[Sidenote: Cesspools.]
Where regularly-flushed masonry-lined side drains are unavailable, the
drainage from houses must be led into masonry-lined cesspools, which
will be cleaned out daily by the municipal sweepers, and the contents
removed in conservancy carts. These cesspools should be semi-circular in
shape, and plastered on the inside with Portland cement. In many cases,
where masonry drains exist, it will be found possible to intercept this
sullage, and purify it through Biological Agency in small tanks, filled
with pieces of vitrified brick, broken so as to pass through a 2–inch
ring. The broken bricks will last for about a year, when they should be
renewed.
[Sidenote: Sullage Filter.]
A drawing of a small Sullage Filter is given in Fig. 18, page 36. The
estimated cost of which is Rs. 180.
[Sidenote: Prompt Disposal.]
It is of the very greatest importance to insist on the prompt disposal
of night-soil and refuse, and all means which aid this, good roads,
proper care and feeding of animals, good carts, and the provision of
houses for sweepers, help to a great extent.
[Sidenote: Registering Private Latrines.]
In order to systematise the removal of night-soil from private latrines,
all these should be registered and numbered according to the beats of
the attendant, or otherwise definitely indicated and located, and the
sweepers told off accordingly.
[Sidenote: Wheels and Axles.]
When purchasing carts especial attention should be paid to the quality
of the wheels and axles. The carts should not be too heavy and must be
of a convenient height to facilitate working.
[Illustration:
SULLAGE FILTER
FIG. 18.

CHAPTER VII.
DISPOSAL OF NIGHT-SOIL AND TRENCHING GROUNDS.
Night-soil is generally disposed of by being buried in trenches, but
these are frequently too deep: purification largely depends on the
action of the ærobic bacilli, that is, the group of microbes which live
close to the surface of the soil and require air for their existence;
these swarm in the top layers of the earth, but are not found at a
greater depth than 1 foot and diminish enormously in number as this is
approached. In order to obtain the best results, both from a
purificative as well as a manurial point of view, the burial should be
merely superficial and not exceeding in depth the limit of ordinary
cultivation, in order to ensure the ground being thoroughly aërated.
[Sidenote: Selection of Site.]
The sites for trenching grounds should be carefully selected; light
sandy soil unshaded by trees and well open to the south and west will
give the best results. They should be well above flood level, at least 5
feet above the highest known flood, situated on the down stream side of
the bazaar, connected by good _pucca_ roads with it to allow of quick
carriage, as time is the most important factor in the disposal of
night-soil, and should not be in the direction of the prevailing winds
with the town. A fringe or belt of bamboos between the town and
trenching grounds will be found of the greatest use in keeping off flies
which might be blown into inhabited neighbourhoods, and which are a most
dangerous factor in disseminating disease.
[Sidenote: Burdwan Trenching Ground.]
At Burdwan in Bengal there is a successful example of what can be done
with trenching grounds from a financial point of view. There the
night-soil of the Northern Section of the Municipality, where the
latrine system is in force, and which has a population of about 23,000,
is mainly disposed of in a permanent trenching ground of 18 bighas in
area. This is collected from private latrines in covered buckets and
deposited in the conservancy carts at the public latrines, whence it is
removed to the trenching grounds, where trenchers are told off for each
latrine group, who excavate the trenches and are in charge of them;
these trenches are 3 feet wide, 1½ feet wide, 12 to 15 feet in length
and 1 foot apart. The carts empty the night-soil in from one end until a
height of 9 inches of liquid is attained, the excavated earth being then
replaced. During the rainy season Indian corn is grown, and in the cold
weather cabbage, cauliflower, Bengal pumpkin, and other kitchen
vegetables, for which there is a ready sale in the local bazaar.
The trenching ground during the current year 1913–14 has been leased out
for Rs. 600.
[Sidenote: Cultivation of Jute.]
In the damp climate of Bengal jute has been found to grow very
luxuriantly on newly-trenched ground and yields an abundant crop; it
exhausts the soil so much that after the crop has been cut the field can
be re-trenched, an important point when the subsoil water is practically
12 or 18 inches from the surface while the jute is growing. Another
advantage in growing jute is that in certain localities there is a
difficulty in finding a market for vegetables grown on a trenching
ground.
[Sidenote: Muzaffarpur Jail.]
In Muzaffarpur Jail the trenches were made 1 foot deep, 1 foot wide, and
1 foot apart, and varying in length according to requirements; 3 inches
of night-soil are filled in and covered over with the excavated earth;
20 trenches are always kept ready, being excavated the day before. Corn
is found to grow luxuriantly after the trench has been filled in for a
month, and other kinds of vegetables, excepting potatoes, after two
months. Urine and sullage water are buried in different fields and at a
considerably greater depth.
[Sidenote: Allahabad.]
At the Government Farm at Allahabad (United Provinces) the system known
as the Allahabad Shallow Trench was in successful operation, and
provided for the whole of the cantonment and half the municipal
population; there is an unlimited area of land available, the soil being
of various kinds, black cotton, sandy loam and stiff clay. The only
crops grown are grass and sorghum, and it is found that the manurial
value of the night-soil is not exhausted for three or four years.
Trenching can, however, be done every third year on the same land
without making it “sewage sick;” land which was worth Rs. 2 will, after
trenching, fetch about Rs. 10 per bigha for seven or eight years.
At Meerut for the year 1911–12 the sale-proceeds of night-soil and city
sweepings amounted to Rs. 12,871, and at Furrakhabad _cum_ Fatehgarh to
Rs. 18,317.
[Sidenote: Allahabad Shallow Trench System.]
The area required for the contents of a 60–gallon conservancy cart is 80
sq. ft., the most suitable dimensions being 16 feet long by 5 feet wide;
3 inches of the top surface of this space is removed and placed on the
embankments of the plot near which the first line of trenches is dug;
the subsoil thus exposed is then well cultivated and pulverized to a
depth of 9 inches, when the contents of the cart are tipped into the
centre of the trench; the liquid matter rapidly sinking into the
loosened soil, while the solid excreta remains on the top in a layer
less than ⅛ inch in thickness; 3 inches of earth are then similarly
removed from the next trench which is parallel to the first, no
intervening space being left, and thrown over the night-soil in the
latter. The practical working is very simple, as all that has to be
done, is to see that a sufficient number of trenches for the daily
supply are dug the day before and the earth from them placed over the
filled ones. It has been found from experience that night-soil, thus
treated, decomposes in less than a week and, if dug then, no trace is
observable; the effluvium disappears after three days, and crops are
successfully grown immediately after trenching. The Shallow Trench
System is by far the most scientific one, but requires a large area of
land, working out to 545 sixty-gallon carts per acre. At Muzaffarpur
during 1912–13, part of the night-soil was sold for Rs. 1,200, and part
of it trenched in the municipal trenching ground, which was leased out
for Rs. 1,045. The practical objection to this system is the fly pest.
It is therefore only applicable where the trenching grounds are remote,
and to the leeward side of the town. Sprinkling chloride of lime or
quicklime on the top of the trenches prevents the breeding of flies. The
researches of Majors Firth and Horrocks, R.A.M.C., published in the
_British Medical Journal_, however, show that the enteric bacilli is
capable of surviving in soil for much longer periods than has been
believed possible. These can exist apparently in ordinary soil for 65
days, in sewage-polluted soil for at least 53 days, while in soil
sufficiently dry to be blown about in dust for 25 days, and for about a
similar period when exposed to a hot summer’s sun. The authors of this
note have also proved experimentally the translation of infective
material from sun-dried and dusty soil by means of wind, as also by
flies which have walked over or fed on polluted earth, indicating the
advisability of treating night-soil, especially from Military
Cantonments, in septic tanks and filter beds before applying it to
soil—_vide_ Chapter IX, page 50.
[Sidenote: Area of Trenching Ground.]
In order to arrive at the area necessary for a deep trenching ground for
a bazaar of 10,000 inhabitants, and assuming that not more than ⅛th of a
gallon of night-soil per head per diem is removed, provision will have
to be made for 1,250 gallons or, say, 200 cub. ft. If the trenches are
made 1 foot wide, 1 foot deep, and 1 foot apart, and are filled with 6
inches of night-soil, 400 cub. ft. will be required daily, or allowing
for roads and divisions between the plots, say 12 acres, for a year’s
work, or, in other words, the area required is, one acre for 833
persons. The trenches should be divided up into plots or sections for
each latrine circle, excavated, when weather permits, at least a week
before they are used so as to aërate the earth; the bottom of the trench
should also be dug up to a depth of 9 inches for the same reason.
The following extract describes somewhat forcibly what may, and
undoubtedly does frequently occur in many instances:—
“Trenching again is a success in dry soils, but a good deal of ground is
required, and sufficient trenching ground is not always available within
practically workable distances of the night-soil producing areas (public
and private latrines), and often enough, whereas it may be quite
successful in a given ground in the hot weather, it will, in the same
ground, however fresh, prove an absolute failure in the rains, when,
owing to the high water-level in the subsoil, everything trenched is
brought to the surface by the gases of putrefaction, and the entire area
trenched becomes a pestilential bog, crawling with maggots, bubbling
with the foulest odours and swarming with blue-bottle flies, whose chief
delight is to frequent the houses in the neighbourhood and infect both
food and drink.”
CHAPTER VIII.
COLLECTION AND DISPOSAL OF REFUSE.
The scavenging of a town and the disposal of the refuse has probably
more effect on its sanitary state than anything else; dirty rags, dead
grass and other refuse lying about, are ideal homes for germs of disease
to live and flourish in, and these, when a shower of rain falls, very
frequently get washed into the water-supply. The modern system of
cremation in specially constructed incinerators is the only safe method
of disposal of town sweepings. Even in England, where the water-supply
is, in the majority of cases, not affected, careful observations have
proved that there is an increased liability to enteric fever in the
localities of refuse heaps. In an Indian bazaar dependent on wells and
tanks for its water-supply, anything more barbarously insanitary than
the filling up of deep tanks with town refuse is hard to imagine. Deep
burial keeps the germs of disease alive, probably for years, in the very
stratum the drinking water is frequently taken from.
[Sidenote: Dust-bins.]
In order to facilitate the collection of refuse, dust-bins are of great
use; they should, however, not be so large as to become unwieldy, as it
is much more preferable to have numerous small ones conveniently placed,
than a few large ones; the simplest shape is a circular one of
corrugated iron, open at both ends, provided with a pair of handles, and
resting on a brick on edge platform, with a groove therein into which
the bin fits, on the same level as the street. When the collecting cart
comes round, the bin is lifted, the contents shovelled into the cart,
and the bin then replaced; these should be cleared at certain fixed
hours, and house-holders ought to be encouraged to have private ones of
small size near their doors if space permits. Fig. 19 is an illustration
of these bins, and being made of galvanized iron are not liable to rust.
They vary in price—for bins 2 feet 9 inches in height and 2 feet in
diameter from Rs. 6 each, without angle iron rings at top and bottom, to
Rs. 12–8 each with rings. These receptacles should not be placed within
50 feet of any well or tank.

FIG. 19.—CORRUGATED DUST OR REFUSE BINS.

The selection of strong and serviceable refuse carts is also a matter of
importance, especially as regards the axles and wheels. Fig. 24, page
48, is an illustration of a cheap but effective type. The cost is Rs.
120 for a cart of 30 cub. ft. capacity, Rs. 150 for 50 cub. ft., and Rs.
200 for 90 cub. ft.
All the working parts should be of standard size, duplicates of which
can be economically purchased and kept in stock in the event of a
breakdown, when they can be easily fitted by unskilled labour. This is
important, as few municipalities have good workshops. The axle box in
the wheels should invariably be the full width of the hub. A new axle,
with axle box and sleeve or jacket to take the wear and tear off the
axle, can be made up at a small cost, Fig. 20. In the Patna Municipality
this is supplied complete for Rs. 9–2–0.
[Illustration:
AXLE, COLLAR, AND BUSH

In Municipalities where the quality of work warrants it, it will be
found economical to maintain a small workshop where repairs can be done,
but this must be properly organized. The following cart Register kept up
in Patna City will simplify control of the carts, and ensure proper
repairs being done. It commences with an Index, each cart is numbered
consecutively, whether it be water, conservancy or refuse cart, and the
number permanently marked on it. At the ledger folios referring to any
cart appears—
1. The number of cart.
2. Date when made.
3. Maker’s name.
4. Where worked (ward and by whom) and below that

This is of course separate from the Stock Register, and may appear to be
a mere detail of organization, but is very useful in administration.
For towns and small Municipalities Incineration is by far the safest,
and in most cases, the most economical method of getting rid of rubbish.
If night-soil be mixed with the rubbish nuisance generally arises.
There are various types of incinerators, but for burning town refuse
only a very simple one, merely a furnace and chimney, is quite enough,
and several of these can be constructed at a very small cost outside a
municipality at convenient centres, where the smoke will not cause a
nuisance. Many of the existing incinerators have been designed to burn
night-soil as well as refuse, as is generally done in military camps and
forts on the frontier.
[Sidenote: Madras Incinerator.]
The Madras type Incinerator is shown in Figs. 21 and 22, page 46. These
were designed to suit local conditions by Mr. C. L. Griffith, while
Engineer of the Corporation, and cost Rs. 100 for masonry and Rs. 25 for
ironwork. There are a considerable number of these at work, distributed
throughout the Municipal area, so as to reduce the load for carting to a
minimum, a very important factor in a straggling town.

]
The Sealkot Improved Type Incinerator is also a suitable and economical
one. A 4′ diameter one is capable of burning about 300 cub. ft. of
rubbish daily, and it costs about Rs. 400. _See_ Fig. 23.
[Illustration:
FIG. 23.
]
[Sidenote: Harrington’s Improved Incinerator.]
Harrington’s Improved Refuse Incinerator has been in use for several
years. Each furnace burns from 500 to 1,500 cub. ft. of refuse in 24
hours, and is attended by one man who works in 8–hour shifts, and who
charges the furnace at the top and removes the ashes from below the fire
bars. The fires do not die out when the furnace is properly charged, and
no coal or other fuel is required. It was patented by Mr. R. R.
Harrington.
[Sidenote: Horsfield Incinerator.]
The Horsfield Back feed continuous grate type with 6 cells, designed to
dispose of 10 tons each in 24 hours, has been adopted for Colombo, the
cost of destruction varying from Rs. 1·30 cents to Rs. 1·50 cents per
ton.
[Illustration:
FIG. 24.—CORRUGATED IRON REFUSE CART.
]
[Sidenote: Burning Refuse in Stacks.]
A large amount of town refuse can be satisfactorily disposed of by
stacking it judiciously and setting fire to it from the windward side,
when it gradually and steadily burns away. This is, of course, only
practicable during the dry weather months when the sweepings are
comparatively dry. In this, as in every case of removal, the beats of
the carts should be systematised and a fixed area allowed to each cart.
[Sidenote: Filling hollows with refuse.]
Where incineration is not practicable the only method of disposing of
street sweepings is by filling up hollows or old tanks, when the
following rules should be observed:—
1. The hollow or pit should first be pumped out quite dry; if wet, a
horrible nuisance is caused.
2. Where the hollow or pit is a large one a section of it should be
bunded in, staked off, and filled up to surface level before the rest is
proceeded with.
3. The sweepings, as soon as ground-level is attained, must be at once
covered over with earth, or the débris from old houses, walls, etc., so
as to prevent them being exposed and acting as breeding-grounds for
flies.
A rapid and effective method of filling a tank when land is available
round its border is to excavate shallow pits parallel to its sides, the
earth from which is thrown into the tank, and the pits then filled in
with sweepings.
A form for regulating the progress of the work of filling up depressions
or tanks is given in Appendix B, page 61.
Unless, under exceptional circumstances, it is most undesirable to fill
up any hollow or tank in the vicinity of any well from which drinking
water is obtained. It may possibly be found the lesser of two evils to
fill up small tanks or hollows in the interior of a bazaar with refuse,
as these are frequently in an undescribable state; the charge made by a
Municipality for doing this should, however, be so adjusted as to admit
of the surface being well covered in with earth, which must, in all
cases, be insisted on. If no charge is made, and no depôt for the refuse
selected, it will be found that the cartmen will sell it by the cartload
to irresponsible persons, when reasonable precautions as to covering in
with earth and selection of site are not possible, the consequence being
that innumerable breeding-places for flies are well distributed
throughout the heart of a densely populated neighbourhood, in places
where earth has been from time to time excavated for building huts.
CHAPTER IX.
BIOLOGICAL SYSTEM FOR THE DISPOSAL OF NIGHT-SOIL.
Since this chapter was written, some 12 years ago much research work has
been carried out in 1906. This was in India first systematised by Dr.
Fowler in his report on “Septic Tanks in Bengal” and has been carried on
by Major Clemesha, I.M.S., Sanitary Commissioner, Bengal, whose work on
“Sewage Disposal in the Tropics” published by Messrs. Thacker, Spink &
Co., Calcutta, is a most useful one and should be consulted by those
interested in the subject.
In the present state of knowledge of the science, it would be unsafe to
discharge the effluent into a water-supply of small volume used for
drinking purposes below the point of discharge, or in fact into any
water which may be a potential source of water-supply, unless it be
first sterilised. This can be easily and economically done with chloride
of lime.
In dealing with the resultant liquid of bacteriological treatment it is
safest to consider it as a possible source of danger, and to discharge
it either into the storm-water drains of a town, on land for irrigation
purposes, for which it is most valuable, or into a large volume of
running water, as circumstances admit of.
The great advantage of bacteriological treatment of night-soil, and one
which it is impossible to overestimate, is, that it enables the excreta
to be disposed of when fresh, eliminates the necessity of stale
night-soil being carted through crowded thoroughfares at a very low rate
of speed, and consequent danger of the food and water-supply of the
people being contaminated by the germs of disease conveyed by flies, or
blown on in the dust. Latrines can be constructed over septic tanks, the
home of the anærobic bacilli, where the excreta at once passes in, or
dumping septic tanks can be worked at the night-soil depôts, where the
stuff is at present collected, as at Darjeeling.
In Military Cantonments, where enteric is generally more or less
epidemic, it is most important that the night-soil be treated by
biological methods before it be applied to the soil, as installed at
most of the mills on the banks of the Hooghly, and at the East Indian
Railway Workshops at Jamalpore.
[Sidenote: Septic Tanks.]
Of the various methods of bacteriological disposal, the closed septic
tank is, for climatic reasons, the most generally suitable for India. In
this the anærobic bacilli are provided with a congenial working place in
the closed tank; and the ærobic ones are similarly provided for in the
filter beds; the open septic tank, however, gives equally good results,
as the scum, which rapidly forms on the surface, and which generally
attains a considerable thickness, enables anærobic conditions to obtain
in the tank itself, but care must be taken that this scum is not broken.
[Sidenote: Filter Beds.]
The ærobic Contact Bed filters are merely open tanks filled with coal,
coke, or large cinders, through which the liquid is allowed to percolate
at intervals. The bacilli live and flourish in these, and do their work
during the periods from 2 to 4 hours the tanks are charged.
The percolating continuous filters are those over which the effluent is
continuously sprinkled and through which the fluid slowly percolates.
Experiments have conclusively proved that good results can be obtained
from either when a suitable sewage is applied.
CHAPTER X.
GENERAL SANITATION.
[Sidenote: Trees and tall crops.]
All the lower branches of trees in crowded areas should be pruned; these
are useless or superfluous for shade, and only impede the free
circulation of air. This should be done by sawing off any branch flush
with the main trunk, or with its main branch. In no case should a ragged
stump be left, and, if possible, the wound should be smeared with tar.
Lopping must be done with a handsaw and in no case with an axe; the best
season for doing this is at the end of the cold weather, but it can also
be done at the end of the rains. The final form of a tree should be a
straight stem up to 15 or 18 feet, without a bough, and above that
height its natural shape whatever that may be. This will allow of free
ventilation of the roads and streets. For the same reason no tall crops,
such as Genera, or Indian corn, should be allowed near houses, and
jungle should be kept cleared as far as possible.
[Sidenote: Tanks.]
Householders should not be allowed to excavate small tanks in their
compounds to procure earth from for the plinths of their houses, as
these become in time mere cesspools, where the inmates bathe, wash their
clothes, and often drink the water. Further, these become suitable
breeding-places for mosquitoes. Plots of ground should be set aside by
Municipalities, where, for proper reasons, earth can be taken. These
common excavations will in time become large tanks, which can be
properly conserved and utilized. For the same reason earth for roads and
railways should not be removed from isolated pits, but should be taken
so that the resultant excavation forms one continuous channel running
parallel with the road, or should be taken in shallow layers so as to
avoid the formation of a pit or hollow, the existence of which is
especially objectionable in the light of recent research as mosquitoes
breed and generate in them, and so spread malarial fever. Where such
hollows exist, the growth of fish should be encouraged, as they feed on
the mosquito larvæ when present.
[Sidenote: Cultivation within urban limits.]
From the experience of troops on service, it is found that camping near
recently turned-up soil is usually followed by fever. Ploughing up of
land for agricultural purposes should, if possible, be prevented within
municipal urban limits. In most municipalities there is a suburban area
which is pretty well all cultivated, but cultivation in densely
populated areas, as often occurs, should be discouraged.
[Sidenote: Dhobies.]
Dhobies should not be allowed to wash clothes in stagnant tanks, as it
has been proved that the spread of parasitic eczema, or dhobies’ itch,
is thereby facilitated. Where a water-supply exists a small washing
platform with taps should be provided free of charge by the
Municipality. Where not, they should be made to wash in running water,
or in tanks specially passed by the medical officer. It is most
important that all dhobies be registered, licensed and told off to the
different ghats; it may be free of cost to them in the first instance,
but after the system has been successfully introduced, well-to-do
employees can easily be induced to pay a small annual fee for superior
accommodation. This will eventually fully cover the cost of the
necessary supervising establishment and incidental expenditure.
[Sidenote: Markets.]
The importance of the regular inspection and control of markets, through
which the food-supply of a large proportion of the inhabitants passes,
can hardly be over-estimated. In these, special accommodation and
water-supply suitable for the articles for sale, _e.g._, fish,
vegetables, meat, and livestock should be provided, and a staff employed
to see that the existing laws are duly enforced, and that the quality of
the food-stuff exhibited for sale is such as should be permitted. Public
slaughterhouses for animals, the inspection of meat, and the disposal of
offal should also be systematically regulated and inspected. The cost of
erecting suitable market accommodation will soon be repaid and the
investment become a source of income to a Municipality if the scheme is
properly worked. The great point is the provision of good ventilation,
drainage, and of a water-supply for flushing purposes. A design of an
inexpensive market of 40 stalls for the Muzaffarpur Municipality
constructed in 1902, at a cost of Rs. 4,786, is given in Fig. 25, page
55. This for the past three years gave an average income of Rs. 253. A
loan of Rs. 4,800 at 4 per cent., repayable in 30 years, would entail an
annual expenditure of say Rs. 278 (_see_ Table of calculations of
repayment of loans by equal instalments, Appendix E, page 68), so the
results there are not satisfactory from a financial point of view.
[Sidenote: Disposal of Dead. Burning Ghâts.]
The scarcity of timber generally prevailing, and its consequent expense,
makes the process of cremation among the poorer Hindus frequently a
farce, the corpse being generally merely charred, and then thrown into
the nearest river, which thereby may be contaminated by the germs of
disease; often the professional cremator does nothing more than throw
the body into the water. It is time that rich Hindus came forward and
constructed proper crematoria in the towns on the banks of the Ganges
for the suitable disposal of their dead. Coal should be used and the
burning ghâts be looked after by Brahmins, as at Kalighat in Calcutta.
In Muzaffarpur, a new burning ghât on the banks of the river, down
stream of the town, was opened under the control of the Municipality. A
waiting-room to shelter the persons accompanying the corpse will be
constructed at the cost of a leading zemindar; and the sale of fuel was
regulated. For the cremation of an adult corpse this is supplied for
about Rs. 2 and for child Re. 1, varying with the seasons, but private
supply was allowed, provided it be sufficient for perfect combustion of
the body. At least 9 maunds of mango wood is required to burn an adult
corpse properly, the rate for this being about 5 maunds for a rupee.

[Sidenote: Burial-grounds.]
Mahommedan burial-grounds should not be allowed near crowded areas, or
the sources of water-supply. In most towns these will be found to be
overcrowded; new ones should be opened under municipal control, as
provided for in sections 254 to 260A, Part VI of the Bengal Municipal
Act. An area of half an acre for every 1,000 Mahommedan inhabitants is
desirable if land is available, but may be reduced to quarter of an acre
where such is very expensive. This allows of the graves being
undisturbed for a period of seven years.
[Sidenote: Ruined houses.]
Where a house has been dismantled, or is in ruins, the owner should be
made either to repair it or remove the materials; the remains of walls
serve as a cover for the committal of nuisances and the deposit of
refuse.
[Sidenote: Building Regulations.]
Building Regulations should be adopted in all Municipalities. Those
framed for Patna City under section 241, Part VI, of the Bengal
Municipal Act, are given in Appendix D, page 63. The rule that no
building in any street shall be higher than the distance from its base
to the opposite side of the street is a very essential one to observe.
In the Bombay Improvement Trust the angle of 63½ from the opposite side
of any street or lane, regulates the height permissible in any building.
APPENDIX A.
MODEL RULES AS TO PRIVATE PRIVIES AND URINALS.
(GOVERNMENT OF BENGAL.)

owner of the privy to form a passage giving access to the privy from the
street.
[Sidenote: Models and type-plans.]
(2) Every notice served under sub-rule (1) must require that such
passage be formed at ground-level, but not less than four feet wide, and
be provided with a suitable door, and must inform the said owner that
the passage may, at his option, be either open to the sky or covered in.
4. Models and type-plans of privies and urinals, approved by the
Commissioners, with estimates of the cost of constructing privies and
urinals in accordance therewith, shall be kept in the Municipal office
and shall be open to inspection by any person at all reasonable times
without charge; but no person shall be bound to construct any privy or
urinal in accordance with any such model or type plan if the same be
constructed in accordance with the other rules contained in this
Schedule.
[Sidenote: Drain.]
5. (1) A drain must be provided for every privy and every urinal.
(2) Such drain must be constructed of some impervious material, and must
connect the floor of the privy or urinal—
(_a_) with a drain communicating with a municipal drain or sewer; or
(_b_) if permitted by the Commissioners, with an impervious cesspool,
the contents of which can be removed either by hand, or by flow
after filtration.
[Sidenote: Floor.]
6. (1) The floor of every privy and urinal—
(_a_) must, if the Commissioners in any case so direct, be made of one
of the following materials to be selected by the owner of the
privy or urinal, that is to say, glazed tiles, artificial stone or
cement; or
(_b_) if no such direction is given, must be made of thoroughly well
burnt earthen tiles or bricks plastered, and not merely pointed,
with cement; and
(_c_) must be in every part at a height of not less than six inches
above the level of the surface of the ground adjoining the privy
or urinal.
(2) The floor of every privy and every urinal must have a fall or
inclination of at least half an inch to the foot towards the drain
prescribed by rule 5; and the platform must be similarly sloped towards
the aperture.
[Sidenote: Walls and roof.]
7. The walls and the roof (if any) of every privy and urinal shall be
made of such materials as may be approved by the Commissioners:
Provided that—
(_a_) in the case of privies, the entire surface of the walls below
the platform shall either be rendered in cement or be made as
prescribed in clause (_a_) or clause (_b_) of rule 6.
[Sidenote: Platform.]
8. The platform of every privy or urinal must either be plastered with
cement or be made of some water-tight nonabsorbent material as
prescribed in rule 6.
[Sidenote: Ventilation of privies in, or adjacent to, buildings.]
9. Every privy or urinal situated in, or adjacent to, a building must
have an opening, of not less than three square feet in area, in one of
the walls of the privy, as near the top of the wall as may be
practicable, and communicating directly with the open air.
[Sidenote: Regulation of service privies constructed for use in
combination with a moveable receptacle for sewage.]
10. Every privy must be constructed in accordance with the following
provisions:—
(_a_) the space beneath the platform of the privy must be of such
dimensions as to admit of one or two moveable receptacles for
sewage of a capacity not exceeding one cubic foot, being placed
and fitted beneath the platform in such manner and position as
will effectually prevent the deposit, otherwise than in such
receptacle of any sewage falling or thrown through the aperture of
the platform;
(_b_) the privy must be so constructed as to afford adequate access to
the said space for the purposes of cleansing such place and of
placing therein and removing therefrom proper receptacles for
sewage;
(_c_) the said receptacles must be water-tight, and must be made of
metal if their capacity is over half a cubic foot, or of
well-tarred earthenware or glazed stoneware if their capacity is
less than half a cubic foot;
(_d_) the door for the insertion and removal of the receptacles must
be made so as to completely cover the aperture.
[Sidenote: Enforcement of the foregoing rules in the case of future
privies or urinals.]
11. (1) If any privy or urinal erected or re-erected after the passing
of these rules is so constructed as to contravene any of the provisions
of this Schedule, the Commissioners may, by written notice, whether or
not the offender be prosecuted under the Municipal Act before a
Magistrate, require—
(_a_) the occupier of the building to which the privy or urinal
belongs, or
(_b_) (if the privy or urinal does not belong to a building) the owner
of the land on which the privy or urinal stands, to make such
alterations as may be specified in the notice with the object of
bringing the privy or urinal into conformity with the said
provisions.

the road, or as nearly parallel to the said line as the Chairman may
consider practicable; and,
(2) If the building to be erected is a public building, or a
dwelling-house—
(_a_) Unless the site is certified by the Overseer to be dry and
well-drained, or to be capable of being dried and well-drained, in
which latter case instruction should be furnished to the applicant
as to what improvements are necessary before a certificate can be
granted. It rests with the Chairman to decide in each case whether
any certificate is necessary at all.
(_b_) If the site is a tank filled up with earth, unless the site has
been filled up for at least five years, with the proviso that if
the foundations reach to the original ground there is no limit as
to time.
(_c_) If the site has been filled up with or used for depositing
rubbish, offensive matter, or sewage, unless the site was so

_Explanation._—If a building be placed at the edge of the road its
height must not exceed the width of the street; but if the building or
one or more of its stories be set back, the height of the building may
be increased as much as the basement of the increased portion is distant
from the adjoining edge of the road.
(2) In the case of any building which is re-erected in a road in
existence at the time when these rules come in force which is less than
25 feet wide but more than 20 feet, the proportion of height to width
may be as five to four up to a limit of 25 feet.
(3) Notwithstanding anything contained in sub-rule (1) or sub-rule (2)
the Chairman may give permission for building houses in the cases of
roads or lanes of less than 20 feet wide, after personal inspection in
each case.
(4) If a building is situated on a corner plot, the height of the
building shall be regulated by the wider of the intersecting streets.
[Sidenote: Level of floor.]
4. The floor or lowest floor of every building erected or re-erected
from the ground-level must be constructed at such level as will admit
of—
(_a_) The construction of a drain sufficient for the effectual
drainage of the building, and placed at such level as will admit
of the drainage being led into some Municipal drain at the time
existing or projected.
(_b_) The provision of the requisite communication with some drain
into which the drainage may lawfully be discharged, at a point in
the upper half of such drain, or with some other outfall into
which the drainage may lawfully be discharged.
[Sidenote: Building over Municipal drain.]
5. No foundation of any building shall be placed over any Municipal
drain, nor shall any superstructure whatever, whether verandah, balcony,
eave, or any other portion of the building, project beyond a vertical
line drawn through the centre of the drain, and if there be no drain,
not beyond 1 foot 6 inches from the edge of the road. But no material or
structure of any kind at or below the level of 6 feet from the ground,
with the exception of entrance culverts, allowed under Rule 7, shall
project over any part of a drain.
[Sidenote: Entrance culverts.]
6. The applications which are filed for entrance culverts must contain
the following particulars:—

traffic:—
(1) two feet.
(2) ten inches.
(3) same size as area of drain up to a maximum of three square feet.
The number of entrance culverts in any building shall not exceed the
number of separate shops or dwelling-houses. The intervening space
between culverts over a drain shall not be covered over by planks, stone
slabs or any other substance.
(_b_) For wheel traffic the size and the nature of the entrance
culverts are left to the discretion of the Chairman.

the 11th idem, namely:—
[Sidenote: Preparation of sketch of project.]
1. (_1_) Whenever a local authority desires to undertake a project for
water-supply or sewerage or a comprehensive scheme of surface drainage,
it shall first cause to be drawn up a sketch of the project roughly
showing its scope and approximate cost.
(_2_) Such sketch may be drawn up either by the Sanitary Engineer at the
special request of the local authority and with the approval of the
Sanitary Board and on payment of the fees prescribed in Rule 8, or by
any firm or person approved by the Sanitary Engineer.
(_3_) The Sanitary Engineer shall, in all cases, act as adviser of the
local authority.
[Sidenote: Submission of sketch, statement and application.]
[Sidenote: Government of Bihar and Orissa Notification No. 7682M., dated
the 8th July 1913.]
2. When the sketch of the project has been drawn up under Rule 1, and it
is estimated to cost Rs. 10,000 or more, or in the case of an estimate
of less than Rs. 10,000 if the financial assistance of Government is
desired, the local authority shall submit it to the Sanitary Engineer,

cost of the project, either from current revenue or by way of loan or
from any other source.
In the case of schemes the total estimated cost of which is less than
Rs. 10,000, not being part of a larger scheme and for which financial
assistance from Government is not required, the sanction of Government

[Sidenote: Conditions precedent to grant of administrative approval.]
3. In order to obtain administrative approval to the execution of the
project the local authority shall satisfy Government—
(_1_) that the cost of maintenance of the projected work can be met by
the local authority from revenue;
(_2_) that any loan required to meet the cost of the work can be
repaid, together with the interest thereon, within the period that
may be prescribed by the Government; and
(_3_) that the work can be done effectually in the manner and for the
cost proposed.
[Sidenote: Procedure after grant of administrative approval. Preparation

[Sidenote: Submission of detailed plans and estimates to Government
through Sanitary Board.]
5. The plans and estimates shall, on completion, be forwarded in

financial aspect of the scheme and the state of public feeling in regard
to it, and, if a loan is required, with an application in the prescribed
form. In the case of drainage schemes the estimates must be submitted in
Sanitary Board’s forms Nos. 21 and 22, copies of which may be obtained
from the office of the Sanitary Engineer, and when the scheme has not

details of the calculations of the sizes and strength of the various
works, and complete information as to the prices on which the estimates
have been framed.
The Sanitary Board, after examining the plans, estimates, report and
application, shall submit them to the Municipal Department of Government
with an expression of their opinion on the merits of the scheme as
finally drawn up.

supervision shall be a condition precedent to the grant of sanction by
the Government.
In the absence of special sanction to the contrary, the local authority
shall agree to such one of the following conditions as may be considered
suitable in each case:—
(_a_) that the work shall be carried out by the Public Works
Department if that Department can undertake it: in such cases an
extra charge of 15 per cent. on the sanctioned estimates shall be
made for supervision, unless the case is one of extraordinary
difficulty, under which circumstances a higher charge may be
imposed under the orders of Government; or
(_b_) that arrangements shall be made with the District Board for the
carrying out of the work under the supervision of the District
Engineer and his staff; or
(_c_) that the work shall be carried out under the supervision of an
Engineer qualified for appointment as a District Engineer

of established reputation:
Provided that the local authority shall not advertise for tenders or
enter into any contract or agreement for the execution of any works in
connection with schemes or parts of schemes which have been sanctioned
by Government under conditions (_b_), (_c_) or (_d_), until the
specification and form of tender for such contract have been examined
and approved by the Sanitary Engineer. No tender or contract for any
such work shall be accepted until it has been submitted to the Sanitary
Board and they have approved the acceptance thereof;
And further provided that when the work is carried out under condition
(_d_), it shall be supervised by an officer appointed for the purpose by
the local authority with the approval of the Sanitary Board, and shall,
while in progress, be periodically inspected by the Sanitary Engineer.
[Sidenote: Report by local authority to the Commissioner in case of
small works.]
7. Where the estimated cost of works amounts to less than Rs. 10,000,

Commissioner of the Division, the agency by which it is proposed to have
the works carried out, and shall follow the instructions issued by him
in the matter.
FEES.
[Sidenote: Bengal Government Notification No. 333T.M., dated the 23rd
May 1911.]
8. The following fees shall be leviable by the Sanitary Board from local
authorities for the work specified against each:—
(_a_) a fee of two per cent. on the estimated cost (excluding cost of
surveys) of all projects and schemes, for which detailed estimates
and drawings are prepared by the Sanitary Engineer;
(_b_) a fee of one-half per cent. on the first Rs. 20,000 and
one-quarter per cent. of the balance of the estimated cost of
schemes and projects, the detailed plans and estimates of which
are examined by the Sanitary Engineer;
(_c_) a fee of two per cent. on the estimated cost of the works, when
contract, drawings, specifications and forms of tender are
prepared by the Sanitary Engineer:
Provided that when both detailed estimates and drawings and contract
drawings, specifications and forms of tender are prepared by the
Sanitary Engineer, an inclusive fee shall be charged of three per
cent. on the estimated cost of the works.
[Sidenote: Bengal Government Notification No. 819M., dated the 10th
April 1908.]
[Sidenote: Government of Bihar and Orissa Notification No. 7682M., dated
the 8th July 1913.]
8_A_. As soon as the services for which fees are leviable under the
preceding rule are rendered, the Sanitary Board shall through the
District Magistrate, demand from the local authority concerned payment
of the fees leviable therefor, and the Magistrate on receipt of notice
of such demand shall recover the said fees and credit them in the local
treasury in favour of the Public Works Department and inform the
Accountant-General, _Bihar and Orissa_, and the Examiner of Local
Accounts, _Bihar and Orissa_.
[Sidenote: Bengal Government Notification No. 333T.M., dated the 23rd
May 1911.]
9. When sketch projects are prepared by the Sanitary Engineer, no charge
will be made for his services or those of his assistants, Government
surveyors, draftsmen, and tracers; drawing materials and the instruments
required for the work will also be provided at Government expense. But
the local authorities will be required to render reasonable assistance
on the spot in the way of survey coolies, supply of survey pegs, fixing
bench marks, etc., and to pay the actual cost of the same. They will
also be expected in each case to provide a suitable office properly
furnished for the use of the surveyors and draftsmen.

(_b_) General cleaning and sweeping with rough country or English bass
brooms, and removing fine dust off the road surface before
treatment by means of soft floor brush.
(_c_) Carrying pitch and tar composition in pails or buckets and
laying it hot half inch thick on dry and clean road surface.
(_d_) Carrying stone metal in cane baskets, spreading and hand-packing
the same carefully to the required chamber, one man for every
three feet of road width to be so treated.
ROLLING.
4. The work of rolling the surface should be commenced as soon as a
section of about 20 or 30 yards in length has been laid, the metalling
gang being kept as busily employed as possible in laying a further
length of materials in the way specified above. The prepared road
surface is to be rolled with a light six or ten-ton roller when the
composition is soft, as it is absolutely necessary to press the
aggregate gently down into the bituminous sub-binder, and at the same
time to entice (rather than to force) the latter in an upward direction,
so as to fill the voids in the metal and finally cover the metalled
surface. Under no circumstances should the rolling be carried to such a
point that the metal exhibits signs of crushing or disintegration. The
roller should be driven over the newly laid materials at its lowest
speed from the side towards the centre and after a few journeys over the
surface if it is found that the sub-binder is not working up between the
voids in the metal and does not cover the metal surface, then such
defective places have to be painted and the whole surface sealed with
composition to prevent the admission of moisture or of any foreign
substance into the road. During the process of consolidation stone
chippings at the rate of 4 cubic feet per hundred square feet should be
used and especially where the floated composition is too soft. If it is
found that any material sticks to the roller wheels a little water
sprinkled on the wheels will at once stop the sticking. The dry surface
may be also sanded if it becomes slippery for horses.
5. All materials to be supplied must be to the satisfaction of the
Engineer. Inferior materials supplied shall be rejected and the
contractor must make good such supply within 24 hours. In default it
shall be competent to the Engineer to procure a supply of the same at
the risk and cost of the contractor from the market or any other agency.
6. The contractor must maintain the roadway for three months after
completion and keep men in attendance to promptly spread stone chips and
road dust on the soft portions and nurse the area cut up by the traffic.
7. The contractor must be careful not to injure existing gas, water or
any other pipes or drains or other underground fixtures. Any damage so
caused must be forthwith reported to the District Engineer, and the
contractor shall make good the same forthwith at his own cost and shall
indemnify and keep indemnified the Corporation from all claims made
therefor. When necessary he shall take up and carefully relay drains and
pipes and lay any additional length that may be ordered by the Engineer
at the cost of the Corporation.
8. The contractor must keep the work properly fenced and lighted from
sun-set to sun-rise, and place such watchmen at any portion of the road
and footpath in which the work is in progress and is still incomplete,
and also round the repairing materials for use, as may be necessary to
protect the public against accidents. He shall indemnify and keep
indemnified the Corporation and its officers and servants from all
liability in respect of any claims for damages or otherwise to person or
property which may be made by any person or persons on account of any
act, misfeasance or neglect on the part of the contractor in carrying on
the work or in connection therewith.
9. The contract will be for four months and the contractors must carry
out all works in accordance with the full programme of work prepared by
the Engineer and take in hand such street or streets as the Engineer may
direct and complete the same within such period as the Engineer may fix
therefor. In default he shall pay to the Corporation liquidated or
settled damages of Rs. 10 (ten) per diem for each and every day beyond
the said period without prejudice to the rights of the Chairman to
cancel the contract and take possession of the work and have it carried
on and completed at the contractor’s risk and cost by any agency
whatever.
10. All damages or other sums due and payable by the contractor may be
received from any moneys due to the contractor by the Corporation.
11. Payments will be made in accordance with the terms of the agreement.
12. The Commissioners do not bind themselves to accept the lowest or any
tender, but reserve the right of accepting the whole or part of the
tender.

EXTRACTS FROM SOME OPINIONS OF THE PRESS.
_The Morning Post, Delhi._
“A very useful little work, which every Municipality in India ought at
once to possess” * * * and is accurately described by the author as “a
concise handbook dealing with the most important points of sanitation of
Indian Bazaars,” and “an endeavour to put the information available on
the subject in a convenient form, so as to facilitate the organisation
and control the working of the Sanitary Department of a Municipality.”
From the first page to the last there is not a superfluous word in the
manual.
_The Bengal Times._
“A work sadly needed in this country, and one everybody concerned in
sanitation, especially if he be a mofussil resident, should possess. We
should think Mofussil Municipal Commissioners and District Board Members
could hardly wish for a better guide.”
_The Pioneer._
“Mr. G. W. Disney, District Engineer, Muzaffarpur, has just published an
excellent pamphlet on _Sanitation of Mofussil Bazaars_, in which he
deals with many problems of urban sanitation in a brief but satisfactory
manner.”
_The Indian Daily News._
“Mr. Disney does not pretend to do more than deal with broad principles
of sanitation, and puts the information available on the subject in a
convenient form, so as to facilitate the organization, and control the
working of the Sanitary Department of a Municipality. This, we think, in
the course of his thirty-five pages of carefully compiled information he
may fairly claim to have done.”
_The Englishman, Calcutta._
* * * “An admirable little work. It ought to be in the hands of every
Municipal Commissioner and all the local authorities in the smaller
towns. Mr. Disney states he is not writing for the big Municipalities,
where special conditions have to be dealt with. At the same time the
little volume contains suggestions that even those responsible for the
good government of Calcutta might read with profit. Mr. Disney is
especially strong on the necessity of a good drainage system. With
regard to town sweepings the author is in favour of incineration.”
_Civil and Military Gazette._
“This is a very useful manual * * * The author does not lay down
expensive and therefore impracticable schemes of sewage disposal, etc.,
but rather directs attention to the possibility of improving the
resources already at the disposal of local bodies. He gives much useful
information and advice as to latrines and urinals, the collection and
removal of night-soil, trenching grounds, disposal of refuse, surface
water drainage, and so forth. The book is illustrated with plans and
drawings.”
_The Indian Planters’ Gazette._
“In his introduction Mr. Disney truly says:—‘The real secret of
Sanitation is the prompt removal of fæcal matter and refuse from the
neighbourhood of inhabited buildings before it has time to decay, as in
the early stages of putrefaction emanations are evolved which are highly
dangerous to health; it is also an admitted fact that the common fly is
a considerable factor in disseminating disease, as it conveys germs on
the pads of its feet from infected matter to the food-supply of the
inhabitants.’ His little _brochure_ deals learnedly and sensibly with
latrines, urinals, the collection, removal, disposal and trenching of
every description of town refuse, with the water-supply from wells, and
finally adds some simple rules for observance of the authorities on the
break out of plague on villages or small towns.”
_The Bengal Times._
* * * “Seeing then how deplorably backward we are in mofussil places,
district, town, suburbs, and country, it seems to us we can hardly do
better than adopt Mr. Disney’s system in Bengal districts. Indeed, why
should Government hesitate to buy up his first edition of _Sanitation of
Mofussil Bazaars_ for gratuitous distribution to all Bengal
Municipalities, in view to adopting his project in its entirety!”
_Dharam and Karam, Calcutta._
(_Published in Bengalee._)
“Mr. G. W. Disney has written a book on Sanitation of Mofussil Bazaars.
There are many large books on the subject of Sanitation, but in a short
pamphlet of 40 pages Mr. Disney has treated the subject-matter, giving
useful rules and instructions in such a brief and concise manner that we
have been pleased to peruse them. Mr. Disney deserves our thanks for his
earnest sympathy with and thought after the inhabitants of the mofussil
towns and bazaars.”
_The Indian Medical Gazette._
“An excellent little pamphlet on ‘The Sanitation of Mofussil Bazaars,’
has been recently published by Mr. G. W. Disney. A concise handbook of
this kind was certainly needed, and this should be of great value to the
Health Officer, the Engineer and the Chairman of Local Boards and
Municipalities.
“The first chapter deals with latrines and urinals, and how sound Mr.
Disney’s views are may be understood from the following extract from the
preface:—
‘The real secret of sanitation is the prompt removal of fæcal matter
and refuse from the neighbourhood of inhabited buildings before it
has time to decay, as in the early stage of putrefaction emanations
are evolved which are dangerous to health; it is also an admitted
fact that the common fly is a considerable factor in disseminating
disease as it conveys germs on the pads of its feet from infected
matter to the food-supply of the inhabitants.’
“The whole little volume is eminently practical; it is well printed,
fully illustrated, and can be strongly recommended to our readers who
will find many hints of use to them in their capacity as Health
Officers. Our only fault with the little book is that it is too short.
It might well have been expanded.”
_The Indian Municipal Journal and Sanitary Record, Bombay._
* * * “The author does not branch out into any startling theories; his
work is more a handbook for those whose business embraces any matter
connected with public cleanliness, and these will find that one of the
most useful features of the book is the information concerning the
makers and the price of every sanitary appliance mentioned. This will be
found very handy by small municipalities who have here a reasonable
standard of cost that will enable them to adjust their expenditure much
more rapidly and avoid the useless trouble and delay of sending out for
tenders—a system not always satisfactory to the purchasing body, and
always troublesome to the tradesman. Mr. Disney very sensibly advises a
wide distribution of small latrines rather than the construction of a
few big ones—it being obvious that the general population will not walk
far for the sake of cleanliness and decency. Mr. Disney preaches the
doctrine of ‘little and often’ in the removal of waste matter, and it is
a point in which every Indian sanitarian will agree with him.”
“True to his theories, Mr. Disney deals with drainage before
water-supply. His recommendations that the water should be pumped from
wells and delivered at some distance from the well-mouth are
particularly sound, for there is no more fruitful source of
contamination than the percolation into the well of dirty water used for
washing in its immediate vicinity.”
* * * “Altogether, Mr. Disney’s book is an indication of the progressive
tendency of sanitation in India—it represents good work done, and will
encourage the doing of more. It is sure to find a handy place on the
desk of municipal secretaries and small town authorities.”
_Extract from letter from the Inspector-General of Jails, Bengal, July
8th, 1902._
“I have just got your little book on mofussil sanitation. * * * It is
altogether admirable, and I am strongly recommending it. It might well
have been longer.”
