Water Conservation

  1. 1. Good for the Environment Good for your Community Good for your Wallet SUBMITTED BY: KAPIL GUPTA (13BCE0354) VATSAL MISHRA (13BEE0159) VARSHIL ANAWADIA (13BCE0266) NAVDEEP KUMAR SAROYA (13BEE0156) SUBMITTED TO : Prof. U. VIJAYLAKSHMI
  2. 2. With only 1% of water available for human consumption, doesn’t it make sense that we should treat our water supply with more respect? VIT UNIVERSITY
  3. 3. ^ High specific heat- cools down and heat up slowly. It also has high latent heat of evaporation – takes high energy for vaporisation ^ Excellent solvent – carrier of nutrients. (O2 and Pathogenic Micro- organisms) ^ Anomalous expansion behaviour – expands when cooling. VIT UNIVERSITY
  4. 4. VIT UNIVERSITY Energy Supply 26% Transport 13% Industry 19% Agriculture 14% Forestry 17% Waste and wastewater 3% Residential & commercial buildings 8% USE OF WATER
  5. 5. • Water conservation encompasses the policies, strategies and activities to manage fresh water as a sustainable resource to protect the water environment and to meet current and future human demand.Climatic Changes, Population, household size and growth and affluence all affect how much water is used. VIT UNIVERSITY
  6. 6. The goals of water conservation efforts include as follows: • To ensure availability for future generations, the withdrawal of fresh water from an ecosystem should not exceed its natural replacement rate. • Energy conservation. Water pumping, delivery and waste water treatment facilities consume a significant amount of energy. In some regions of the world over 15% of total electricity consumption is devoted to water management. • Habitat conservation. Minimizing human water use helps to preserve fresh water habitats for local wildlife and migrating waterfowl, as well as reducing the need to build new dams and other water diversion infrastructures. VIT UNIVERSITY
  7. 7. • Today the earth is in the need of water conservation as the quantity of water is going down day by day • Though we say that the Earth is a Blue Planet ,the reality is that only 3% of the total water available is fit for drinking. • Out of that 3% also , 2.997% is locked up in polar ice caps, and only 0.003 % is there in form of surface & ground water • The rate is still declining and the reason is...... VIT UNIVERSITY
  8. 8. • WATER POLLUTION • Water pollution is a major global problem which requires ongoing evaluation and revision of water resource policy at all levels (international down to individual aquifers and wells). It has been suggested that it is the leading worldwide cause of deaths and diseases, and that it accounts for the deaths of more than 14,000 people daily. VIT UNIVERSITY

  11. 11. 1) When annual rain fall is below normal and less than evaporation, drought conditions are created. 2) Unlike flood, it is not a distinct event. 3) It is often caused by the complex factor. Drought is an extended period when a region notes a deficiency in its water supply whether surface or underground water. A drought can last for months or years, or may be declared after as few as 15 days VIT UNIVERSITY
  12. 12. • It is the extreme deterioration of land in arid and dry sub-humid areas due to loss of vegetation and soil moisture. • It results chiefly from man-made activities and influenced by climatic variations. Consequence of desertification: 1. Economic loss 2. Worsening drought 3. Lowering living standards 4. Environmental refuges VIT UNIVERSITY
  13. 13. Water conflict is a term describing a conflict between countries, states, or groups over an access to water resources. 1. Local Level: Example: Between villages or streets or houses 2. National level: Example: Cauvery river – between Karnataka and Tamil Nadu 3. International level: Example: Jordan river water conflict between Sudan, Egypt and Ethiopia. VIT UNIVERSITY

  15. 15. MINAMATA DISEASE:CAUSED DUE TO METHYL MERCURY CONTAMINATED WATER.IT WAS SEEN IN JAPAN IN 1953 ITAI –ITAI:THIS DISEASE IS CAUSED DUE TO HEAVY METAL CADMIUM.IT WAS SEEN IN JAPAN. FLUOROSIS:IT IS CAUSED DUE TO EXCESS OF FLUORIDE CONTENT IN DRINKING WATER.IT CAUSES WEAKNING OF TEETH AND BONES. BLUE BABY SYNDROME:IT IS CAUSED DUE TO PRESENCE OF EXCESS OF NITRATE IN DRINKING WATER VIT UNIVERSITY
  16. 16. Rainwater Harvesting for Consumption • Cost less than $1500 to build • Softer Water: 5mg/gal of dissolved minerals as compared to 500 in city water. • Cut water use by 95% • Many use similar system for laundry and toilets. VIT UNIVERSITY
  17. 17.  Rain Water Harvesting is capturing and storing rainfall to irrigate plants or to supply people and animals.  A well-designed system will also decrease your landscape maintenance needs.  All you need for a water harvesting system is rain, and a place to put it.   A "catchment" is any large surface that can capture and/or carry water to where it can be used immediately or stored. VIT UNIVERSITY
  18. 18. Wash laundry and dishes with sufficient amount of water only Always turn off running water Take shorter showers Eliminate any and all leaks Reduce the flow of toilets and showerheads VIT UNIVERSITY
  19. 19. ADVANTAGES OF WATER CONSERVATION
  20. 20. ADVANTAGESOF WATERCONSERVATION  I don’t think anyone can say that water conservation has disadvantages.  Factories produce harmful waste products which if purified and discarded help in keeping the surrounding of the factories safe and keep local residents out of health problems.  Rivers and lakes will remain clean.  Hence can be used for irrigation and cultivation purposes. VITUNIVERSITY
  21. 21. ADVANTAGESOF WATERCONSERVATION  Fishes and other aquatic life forms can breathe well in the water.  Various treatment methods like trickling filter method, activated sludge process and RBC help in purifying sewage water.  Nitrogen and phosphorus in sewage remains in the effluent from secondary treatment. These inorganic nutrients can cause eutrophication. VITUNIVERSITY
  22. 22. ADVANTAGESOF WATERCONSERVATION  Saves money.  Minimizes water pollution and health risks.  Protects drinking water resources.  Reduces the need for costly water supply and new wastewater treatment facilities. VITUNIVERSITY
  23. 23. CONCLUSION  Concluding I would like to say that WATER is an essential natural resource and a very important part of human life and hence should be conserved.  This will help us and our future generation to live a longer, better and a peaceful life on this planet. “ SAVE WATER, SAVE LIFE…! ” VITUNIVERSITY
