Abstract: Water is crucial factor in our life. It is one of fundamental needs of human being. As far as our health is concerned the water should be fit for drinking, it should not contain any undesirable substances rendering it unfit for drinking and domestic use. For such water we have to depend on sources of water such as river, lake , well etc. but to make it upto the standards of drinking water it should be treated1. In big cities municipal corporation supplies water to the people after treating it in treatment plant. In pimpri & chinchwad city PCMC treats and supplies water to city. Corporation divided city in 46 sectors to distribute water. Samples were collected from each of these sectors and conducted various tests such as hardness test, chloride content test, etc. To examine the contamination of water at tap sources. In this study it was found that the water is pure up to all standards except residual chlorine in certain sectors. So it is concluded that what care should be taken for distribution to such sectors. Keywords: pH Test, Alkalinity Test, Chloride Test, Total Dissolved Solids, Total Hardness Test, Residual Chlorine Content.

. In big cities municipal corporation
supplies water to the people after treating it in treatment plant. In pimpri & chinchwad city PCMC treats and
supplies water to city. Corporation divided city in 46 sectors to distribute water. Samples were collected from each
of these sectors and conducted various tests such as hardness test, chloride content test, etc. To examine the
contamination of water at tap sources. In this study it was found that the water is pure upto all standards except
residual chlorine in certain sectors. So it is concluded that what care should be taken for distribution to such
sectors.

1. INTRODUCTION
About 72% of earth surface is water cover, out of which 97% is content in ocean remaining 3% is fresh water3
, out off
only 1% is only available for drinking. Due to industrialization and urbanization the remaining 1% of water is getting
polluted and making it unworthy for drinking. Every major city treatment plants to treat this water and supply for drinking
in our project we took case study of pimri-chinchwad water supply network. PCMC area is divided into 46 water supply
zones. Test to be conducted for the assessment of quality of drinking water
2. MEHODOLOGY
2.1 Sampling:
The value of any laboratory results depends on the sampling integrity of sample. The object of sampling is to collect a
portion of water small enough in volume to be conveniently handled in the laboratory. It must be collected in such manner
that nothing is added or lost in portion collected and no change occurs during the time between collection and laboratory
examination. Unless this conditions are met, laboratory results may be misleading and worse than no results4
.
2.2 Types of Tests:
a) pH Test
b) Alkalinity Test
c) Chloride Test
d) Total Dissolved Solids

4.1Interpretation of Results:
Chlorine is essentially added in water supply chain to kill any bacteria remaining or may have entered into supply chain.
The fresh tap water will contain some amount of chlorine whose value goes on decreasing as time passes. Nearly about
pamount of chlorine in supply chain. Many of these areas are closed by treatment plant , as water has to travel less
distance to arrive at tap so chlorine content is high.
Whereas some very far away areas have very low chlorine content but some of these areas are underdeveloped or slum
areas and are areas which should be having high chlorine contain but due to distance and time taken by water to rich tap is
high which reduces chlorine content to very low value.

5. CONCLUSION
1. From above test we are concluding that the test results obtained were within given standard limits except for residual
chlorine.
2. In case of residual chlorine the standard value is 0.20mg/lit but in some cases it was obtained to be very high such
intake of water with high chlorine content on longer periods can lead to serious health problem as it has been reported
to cause Asthma6
, episodes of dermatitis5
, and increase risk of bladder cancer7
.
Thus we conclude that water is safe for drinking
3. We want to recommend that there must be proper check point in distribution system in each zone to check the amount
of residual chlorine in water in that zone.
4. Proper mechanism must be put in place so that instead of adding chlorine at treatment plant in concentrated amount, it
can be added zone wise in small amounts which will fairly distribute the concentration of residual chlorine
