INTRODUCTION
2. 2
Drinking Water Supply is one of the most important sectors for
intervention. There are existing water supply systems in the towns
proposed to be covered. The demands for the system improvements in
these towns can be very large. Theproposals for improvement of the water
supply will therefore have to be tailored to be within the limitations of the
funds available for the sector in the town. Acomparative benefit/cost of
different works should be considered and the mostbeneficial and cost
effective proposals have to be prepared after interaction with the PHED
and the local city level authorities. The following guidelines should
beconsidered during taking up projects under this sector:
Specifically, this Report provides Garfield County with evidence that
provision has been Made for an adequate potable treatment meeting the
Colorado Department of Public Health and Environment ("CDPHE") drinking
water quality standards for the Project, as Part of the overall water supply,
and that an adequate potable water delivery system Can be designed,
constructed and made available. With respect to the raw water delivery to
the Project, the design of the raw water supply and distribution system
is Documented in the Raw Water Supply and Distribution Plan. The Water
Supply Plan demonstrates that the legal supply and source for the potable
and raw water systems is available .
. 2 Objective
The objective of public protected water supply system is to supply safe and
cleanwater in adequate quantity, conveniently and as economically as possible.
Watersupplied should be free from pathogenic organisms, clear, palatable and
free fromundesirable taste and odour, of reasonable temperature, neither
corrosive nor scaleforming and free from minerals which could produce
undesirable physiologicaleffects.
A. WATER SUPPLY SOURCE
3. 3
In order to design a water distribution system, it is appropriate to first
consider the Likely sources. These potential sources include the use of
existing or development of alluvial wells and surface water diversions.
More specifically, if the potable water supply will be provided by the
RFWSD, alluvial wells located in the Aspen Glen and Coryell Ranch
subdivision and surface diversions from the Roaring Fork River using the
Robertson Ditch Rose Ranch Enlargement, Posy Pump and Pipeline (Iron
Bridge Subdivision), or the RBC Roaring Fork Diversion (River Edge
Colorado) water rightswould be utilized. However, if the Project is served by
a privately-operated and self-sufficient public system, the potable water
supply will come from surface diversions from the Roaring Fork River using
the RBC Roaring Fork Diversion (River Edge Colorado).
Water source for our project is Sepaged water from Gauge river collected to
Intake well Khutanpara Baikunthpur from there pump to Treatment plant for
filtaratoin of raw water after filtersation water send to high head water tank
and to water tank by Gravitaional distribution we supply the water to
consumers.

DEVELOPMENT AND DISTRIBUTION OF
WATER TESTING KIT
Environmental awareness plays a vital role in prevention and control of
pollution in industrial as well as at community levels. Assessment of water
quality in a particular water body to understand any impact of water
pollution needs a laboratory facility, which is not possible to have it in
everywhere. Keeping this fact in view, the Central Pollution Control Board
has developed a Water Testing Kit (WTK) to assess the water quality of
surface, ground and potable water bodies in field condition. The kit designed
and developed by a team of scientists of the Board is intended for students,
NGOs and public.
This Water Testing Kit (WTK) has been fabricated as a portable laboratory
provided with the apparatus and reagents needed for the field testing to
assess the quality of water under field conditions. The water testing field kit
enables the user to assess the physical, chemical, bacteriological and
biological quality of water in the field.
The main objectives of this WTK are to create mass awareness among
students, NGO's and the public and to provide low-cost Water Testing
facility. The kit has been designed not only to test water samples but also to
serve as a scientific, informative, thought-provoking and educative tool to
students, NGO's and the public. It can be used by even person with little or
no knowledge of analytical techniques by following the instruction
mentioned in the manual. The kit will definitely provide the information
whether pollutants are above or below the permissible limit based on
quantitative as well as qualitative analysis.

1) DETERMINATION OF pH
2) DETERMINATION OF TURBIDITY
3) DETERMINATION HARDNESS
4) DETERMINATION OF RESIDUAL CHLORINE
5) DETERMINATION OF CHLORIDES
6) DETERMINATION OF SULPHATE
1) DETERMINATION OF pH
APPARATUS REQUIRED:
1) Ph meter with electrode
2) Beakers
3) 100 ml standard flasks
6. 6
4) Funnels
5) Tissue papers
6) Wash bottle
THEORY:
Fresh distilled water has a pH of 7. Acidic waters have a pH of 0to 7, whereas
alkaline waters have a pH of 7 to 14. Ammonia and Lime solution have pH of about
12 where as many cool drinks, lime juice, battery, etc. have pH of less than 4. As
pH is measured on a logarithmic scale, water having a pH of 6to 10 times more
acidic than the natural water, water having a pH of 4 is 1000 times more acidic
than water with pH 7 and a pH of 2 is 100000 times more acidic than a pH of 7. PH
of a solution can be found easily by using pH strips (paper) or a pH meter gives very
accurate values whereas pH strips gives approximate values. pH is determined by
the measurement of electromotive force of a cell comprising an indicator
electrode responsive to hydrogen ions (such as glass electrode) immersed in the
test solution and a reference electrode is usually achieved by means of a liquid
junction, which forms a part of the reference electrode. The ‘emf’ of this cell is
immersed with pH meter. This is high impedance electrometer calibrated in terms
of pH.
2) DETERMINATION OF TURBIDITY
APPARATUS REQUIRED:
1) Nephelometric turbidity meter,
2) Nessler’s tubes with stand,
3) Standard flasks,
4) Wash bottle.
PRINCIPLE:
7. 7
The tungsten filament produces a converging light beam. It is then scattered by the
suspended particles present in the given sample of water. The scattered light is
sensed by a photo cell kept at 90 in light path and the amount of scattered light is a
direct measure of tubidity of the solution.
As table and regulated DC supply is used to excite the lamp. Similarly a high
gain amplifier is used to convert the photocell output into measurable signal.
THEORY:
Turbidity is a measure of the transparency of the water. Turbidity is the property
of water because of which it offers resistance to passage of light. It is caused by
suspended solids (such as silt and clay), living or dead algae and other
microorganisms. It depends on the type of soil over which water has run and the
velocity of run-off. As sand is a good filtering methods, ground waters are less
turbid. River/ canal waters are highly turbid (upto 300 NTU) during monsoon.
River water have negligible turbidity during summer, as river flow is mostly
contributed by ground water during summer. Turbidity is measured by “Turbidity
Rod” or “Jackson Turbidity Meter” (in JT Units) or by “Nephelometer” (in NT Units
). Insoluble particles of soil, organics, micro-organisms and other inorganic
material, impede the passage of light by scattering and absorbing rays. The
scattering of light is generally proportional to the turbidity. The turbidity is thus
measured from the amount of light scattered by the sample taking a reference
with standard turbidity suspension. Turbidity is expressed as the amount of
suspended matter in liquid in parts per million or milligrams per liter, determine
by the optical observations. The standard unit of turbidity is “that produced by
one part of finely dissolved silica in one million parts of distilled water” for
potable water allowable turbidity is between 5 to 10 mg/l.
3) DETERMINATION HARDNESS
APPARATUS REQUIRED:
1. Burette,
8. 8
2. Pipette,
3. Conical flask,
4. Beakers,
5. Standardflask,
6. PVC bottle.
PRINCIPLE:
Hardness is generally caused by the calcium and magnesium ions present in water.
Polyvalent ions of some other metals like strontium, iron, aluminum, zinc and
manganese etc. Are also capable of precipitating the soap and thus contributing to
the hardness. However, the concentration of these ions is very low in natural
waters, therefore,hardness is generally measured as concentration of only calcium
and magnesium which are far higher in qualities over other hardness producing
ions.
4) DETERMINATION OF RESIDUAL CHLORINE
APPARATUS:
1. Conical flasks,
2. burette, pipette,
3. Standard flask.
PRINCIPLE:
Chlorine is primarily added to the water for destroying the harmful micro
organisms, presence of excess chlorine intensities the taste and odours of many
other compound such as phenol, etc., It may also be harmful to many aquatic
microorganisms in combination with ammonia.
Chlorine is a strong oxidizing agent and liberates iodine from potassium iodide. The
liberated iodine is equivalent t the amount of chlorine and can be titrated against
sodium thiosulphate using starch as an indicat
5) DETERMINATION OF CHLORIDES
9. 9
APPARATUS REQUIRED:
o Conical flasks,
o Burette
o Pipette,
o Standard flask,
o Funnel
o Wash bottle
PRINCIPLE:
Silver nitrate reacts with chloride to form very slightly soluble white precipitate of
AgCl2 . At the and point when all the chloride get precipitated, free silver ions
react with chromate to form silver chromate of reddish brown color
6) DETERMINATION OF SULPHATE
APPARATUS REQUIRED:
1) Silica crucible,
2) Desiccators,
3) Ash less filter paper,
4) Beaker.
10. 10
PRINCIPLE:
Sulphate is precipitated as barium sulphate in the hydrochloric acid medium by
addition of barium chloride solution. The reaction is carried out near the boiling
temperature. The precipitation is filtered, washed to remove the chlorides, cried or
ignited and weighed as BaSO4.
Many substances interfere in performing this test. Suspended matter, Silica, nitrate
and sulphate lead to the positive errors where the results are on the higher side.
Alkali metal sulphate causes the low results. Presence of other metals such as iron
and chromium also yield low results due to the formation of metals sulphates.
9. DISTRIBUTION SYSTEM
The purpose of the distribution system is to convey wholesome water to the
consumer at adequate residual pressure in sufficient quantity at convenient points.
Water distribution usually accounts for 40 to 70% of the capital cost of the water
supply project. As such proper design and layout of the system is of great
importance. Metering is recommended for all cities.
• In the continuous system of supply, water is made to consumer all the
twenty-four hours a day, whereas in the intermittent system, the consumer
gets supply only for certain fixed hours (a few hours in the morning and a
few hours in the evening). The intermittent supplies system suffers from
several disadvantages and does not promote hygiene and hence wherever
possible, intermittent supply should be discouraged and is uneconomical.
• To ensures equalization of supply of water throughout the area Zoning in
11. 11
the distribution system is essential. The zoning depends upon (a) density of
population (b) type of locality (c) topography and (d) facility of isolating
for assessment of waste and leak detection. If there is an average elevation
• water could be conveyed by gravity or by pumping, or gravity-cumpumping.
Any of these three modes could be selected based mainly on the
elevation of the source of supply with respect of the town
• The location of service reservoirs is important for regulation of pressures in
the distribution system as well as for coping up with fluctuating demands.
In a distribution system fed by a single reservoir, the ideal location is a
central place in the distribution system, which effects maximum economy
on pipe sizes, Where the system is fed by direct pumping as well as through
reservoirs, the location of the reservoirs may be at the tail end of the
System. If topography permits, ground level reservoirs may be located
taking full advantage of differences in elevation. Even when the system is
fed by a central reservoir, it may be desirable to have tail end reservoirs for
the more distant districts. These tail end reservoirs may be fed by direct
supply during lean hours or booster facilities may be provided.
Method of Distribution
The main object of a Distribution system is to develop adequate water
pressure at various points of the consumers taps. Depending upon the level of the
source of water that of the city, Topography of area, and other local conditions
and consideration, may be forced in to the Distribution system in the followin
three ways.
12. 12
1. By Gravitational System
2. By Pumping System
3. By combine Garavity and Pumping System.
1. By Gravitational System –
In this system the water from the high levelled source is disributed to the
consumers at lower levels, by the mere action of gravity without any pumping. For
proper functioning of this system, the difference of head available between the
source and the localities, must be sufficient enough, as to maintain adequate
pressure at the consumer door-steps, after allowing the frictional and other losses
in the pipe. This method is the most economical and reliable, since no pumping is
involved at any stage. However, it needs a lake or a reservior as a source of supply..
2. By Pumping System –
In the pumping system, the traded water is directly pumped in to the distribution mains
without storing it anywhere. For this reason, this system is also sume times called
pumping without storage system.
3. By combine Garavity and Pumping System.
13. 13
In this system, the treated water is pumped at a constant rate and stored into an
elevated distribution reservoir, from where it is distributed to the consumers by
the mere action of gravity. Sometimes the entire a times it is pumped into the
distribution mains and reserviors, simultaneously. This meted thus, combines
pumping as well as gravity flow, and is some times called pumping with storage
system.
Here for Baikunthpur area we addopted Gravitational distribution
system…
