•Badi Lake

Our Main Concern :

•Fateh Sagar Lake

The Lake is situated in the north of Udaipur city, as apartof the western lake frontage. The lake was constructed inthe year 1678A.D. and then renovated in 1889A.D. byMaharana Fateh Singh. The dam of this reservoir is720m in length and about 100m in breadth. The lake hasa catchment area of 53.66km.The greatest depth of theLake lies near the middle of the dam i.e. 13.4 m. Thetotal spread is 4.0 sq. kms.

•Pichola LakeA Banjara chieftain initially constructed the lake in the14th century. Rana Udai Singh further raised itsembankment in 1560 A.D. The water spread of the lakeis 6.96 kms. And has a maximum depth of 10.5 mtowards the west where the Kotra River drains into thelake. The lake forms the main source of drinking waterfor the city. The river Sisarma, a tributary of the Kotra isthe chief source of water to the lake

But …………………… in recent years the pollution (majorly water pollution ) level has increased so much that udaipur is loosing its scenic beauty …………..

• The aquatic species are suffering the most. Fishes are dying because of non availability of Oxygen since the water surface is covered with watercress .

• Also chemical water is directly dumped in the water bodies without any treatment which is affecting aquatic life. •Accumulation of bioaccumulative and non-biodegradable pollutants in animal bodies which is leading to the death of aquatic animals and plants and this effect is than continued in the food chain

Effect on HUMANS :

•Increased incidence of tumours, ulcers due to nitrate pollution. •Increased incidence of skin disorders due to contact with pollutants. •Increased incidence of constipation, diarrhea and infections to intestine. •Dangerous effects on growing foetus in pregnant women. •Concentration of pollutants due to bioaccumulative pesticides. through secondary and tertiary food chain in case of non - vegetarians. •Still births, abortions and birth of deformed children. •'Blue baby' disease caused by methane globinemia - which results in asphyxia (reduced O2 supply). •Reduced activity of immune system. •Loss of memory power and reduced mental sharpness. •Water borne diseases like jaundice, hepatitis, gasteroenteritis will be more prevalent due to water pollution. •Reduced bone development and muscular development. •Reduced male fertility. •Shifts in physiological cycles of human body.

Udaipur Purification Plant:There are 3 main water purification plants in Udaipur :

1) Doodh Talai

2) Jaisamand

3) Udaisagar

We visited Doodh Talai plant

Pic-1

Pic-2

In this step chlorine gas and alum are added in certain amount of ppm depending on tubidity of water.

Pic-3 Pic-4

Water flowing from inside to outside tank

After first step treatment water is collected in the centre tank and allow to stand. So that the flux formed is seperated. Then this water is pumped from bottom to top in outer tank, known as sedimentation tank. These tanks are 20 ft deep.

Pic-5

Pic-6

Water from the sedimentation tank is passed into these two filter bed. In these bed the water is passed through the bed of sand and gravels.

By the end of these processes the water is free from macroscopic pollutants.

Pic-7

This water is transferred to a storage tank where chlorine gas is passed through it in optimum amount.

Pic-8

This collected water is pumped to different parts of the city.

Chlorine gas cylinders

Measures going on in the city to control this\

• Rajasthan Patrika is running “AMRATAM JALAM” program which is receiving great response from the public

• Jheel Sanrakshan Society, Udaipur too is working along with the public cooperation and working at a great pace.

• Clubs of udaipur like .. Lions’ Club , Rotary Club , Field Club and many Non Governmental Organisations too are running many programs for saving the beauty of UDAIPUR.

SUGGESTIONS :

• Bury or flush pet wastes down the drain.• Recycle as much plastic and other materials as possible. •Dispose of all unused household hazardous wastes at your local disposal site. •Use NATURAL alternatives.• Put litter into garbage cans, never throw it into storm drains or the street.

More suggestions please!!!

• Arpit Harkawat (Y10uc080)

•Kapil Tilwani (Y10uc142)

•Nikunj Bhargava (Y10uc196)

It’s our humble request to all of you to please save the water bodies and to cooperate the working teams in their motive.

Thank You.
