  11. 11. • The aquatic species aresuffering the most. Fishes aredying because of non availabilityof Oxygen since the watersurface is covered withwatercress .• Also chemical water is directly dumped in the water bodies without anytreatment which is affecting aquatic life.•Accumulation of bioaccumulative and non-biodegradable pollutants in animalbodies which is leading to the death of aquatic animals and plants and this effectis than continued in the food chain
  12. 12. Effe ct o n HUM N : AS•Increased incidence of tumours, ulcers due to nitrate pollution.•Increased incidence of skin disorders due to contact withpollutants.•Increased incidence of constipation, diarrhea and infections tointestine.•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 - whichresults in asphyxia (reduced O2 supply).•Reduced activity of immune system.•Loss of memory power and reduced mental sharpness.•Water borne diseases like jaundice, hepatitis, gasteroenteritiswill be more prevalent due to water pollution.•Reduced bone development and muscular development.•Reduced male fertility.•Shifts in physiological cycles of human body.
  13. 13. Udaipur Purification Plant: There are 3 main water purification plants in Udaipur : 1) Doodh Talai 2) Jaisamand 3) UdaisagarWe visited DoodhTalai plant
  14. 14. Pic-2 Pic-1In this step chlorine gas and alum areadded in certain amount of ppmdepending on tubidity of water.
  15. 15. Water flowing from inside to outside tank Pic-3 Pic-4After first step treatment water is collected in the centre tank andallow to stand. So that the flux formed is seperated. Then this wateris pumped from bottom to top in outer tank, known assedimentation tank. These tanks are 20 ft deep.
  16. 16. Pic-5
  17. 17. Pic-6Water from the sedimentation tank is passed into these twofilter bed. In these bed the water is passed through the bed ofsand and gravels.
  18. 18. By the end of these processes the water is free from macroscopicpollutants. Pic-7 This water is transferred to a storage tank where chlorine gas is passed through it in optimum amount.
  19. 19. Pic-8This collected water is pumped to different parts of the city.
  20. 20. Chlorine gas cylindersChlorine gas
  21. 21. 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 workingalong with the public cooperation and working at a greatpace.• Clubs of udaipur like ..
