Uses of water include agricultural , industrial , household , recreational and environmental activities. Virtually all of these human uses require fresh water .Water Water Every Where But Not A Drop To Drink: Water Water Every Where But Not A Drop To Drink 97% of the water on the Earth is salt water, and only 3% is fresh water of which slightly over two thirds is frozen in glaciers and polar ice caps. The remaining unfrozen freshwater is mainly found as groundwater, with only a small fraction present above ground or in the air.Fresh Water Sources: Fresh Water Sources Surface Water Under River FlowFresh Water Sources: Fresh Water Sources Ground Water Frozen WaterFresh Water Uses: Fresh Water Uses Agriculture IndustrialFresh Water Uses: Fresh Water Uses Household RecreationIncreasing water scarcity: Increasing water scarcity It is caused by over exploitation, excessive use and unequal access to water among different social groups. Increasing population, intensive industrialization, deforestation and mismanagement of water resources have caused a crisisManagement, Conservation and Harvesting: Management, Conservation and Harvesting Water Management Harvesting Conservation Multi purpouse River project Reducing wastage of water Rain water harvestingMulti Purpose River Project: Multi Purpose River Project Multi purpose river project is such a scheme which serves several purposes at one and the same time because of their uses they are rightly called the temples of modern India by Pt. Nehru. Such projects help in checking floods. Ample of water is available for irrigation. These projects help in electricity generation. They are used for in land navigation and fish-breeding.Water conservation: Water conservation What you can do to conserve water ? Use only as much water as you require. Close the taps well after use. While brushing or other use, do not leave the tap running, open it only when you require it. See that there are no leaking taps. Use a washing machine that does not consume too much water. Do not leave the taps running while washing dishes and clothes.PowerPoint Presentation: Install small shower heads to reduce the flow of the water. Water in which the vegetables & fruits have been washed - use to water the flowers & plants. At the end of the day if you have water left in your water bottle do not throw it away, pour it over some plants. Re-use water as much as possible Change in attitude & habits for water conservation Every drop counts!!!Rain Water Harvesting : Rain Water Harvesting Rain Water Harvesting (RWH)- It is a process of collecting, conveying & storing water from rainfall in an area – for beneficial use. Storage is done in tanks, reservoirs, underground storage- groundwater It is neither energy-intensive nor labour-intensivePowerPoint Presentation: RWH - yield sufficient amounts of water. For an average rainfall of 1,000mm, approximately four million litres of rainwater can be collected in a year in an acre of land (4,047 m 2 ), post-evaporation. Rain Water HarvestingRain Water Harvesting– Advantages : Rain Water Harvesting– Advantages 1.Provides self-sufficiency to water supply. 2.Reduces the cost for pumping of ground water. 3.Provides high quality water, soft and low in minerals. 4.Improves the quality of ground water through dilution when recharged.PowerPoint Presentation: 5. Reduces soil erosion & flooding in urban areas. 6.The rooftop rain water harvesting is less expensive & easy to construct, operate and maintain. 7. In desert, RWH is the only relief. 8. I n saline or coastal areas & Islands, rain water provides good quality water.PowerPoint Presentation: Save It Conserve It Preserve ItPowerPoint Presentation: Thank You By Ikshit Singhal You do not have the permission to view this presentation.
