Rain water harvesting vaibhav

  1. 1. .ppt (1)<br />PRESENTATION ON <br /> RAIN WATER HARVESTING<br />BY:<br />VAIBHAV SHARMA<br />
  2. 2. .ppt (2)<br />What Is Rainwater Harvesting?<br /><ul><li>RWH consists of simple systems to collect, convey, and store rainwater. Rainwater capture is accomplished primarily from roof-top, surface runoff, and other surfaces.
  3. 3. RWH either captures stored rainwater for direct use (irrigation, production, washing, drinking water, etc.) or is recharged into the local ground water and is call artificial recharge. </li></li></ul><li>.ppt (3)<br />Why Rainwater Harvesting?<br /><ul><li>Conserve and supplement existing water resources
  4. 4. Supply water at one of the lowest costs possible for a supplemental supply source.
  5. 5. Commitment as a corporate citizen - showcasing environmental concerns
  6. 6. Replenishing local ground water, where lowering of water tables has occured</li></li></ul><li>.ppt (4)<br />Why Not RWH?<br /><ul><li>Not applicable in all climate conditions over the world
  7. 7. Collected water quality might be affected by external factors
  8. 8. Performance seriously affected by climate fluctuations that sometimes are hard to predict
  9. 9. Collected rainwater can be degraded with the inclusion of waste water runoff</li></li></ul><li>.ppt (5)<br />Condensation<br />Let’s take a look at<br />The Water Cycle<br />Precipitation<br />Evapotranspiration<br />Evaporation<br />Infiltration<br />Surface Runoff<br />Surface Water<br />Consumption<br />Groundwater<br />Sea water intrusion<br />
  10. 10. .ppt (6)<br />Condensation<br />Average Rainfall <br />Average Annual and Monthly Precipitation – Average rainfall over one year period and monthly intervals and usually based on global atmosphere<br />Precipitation<br />Consumption<br />Groundwater<br />Surface Water<br />
  11. 11. .ppt (7)<br />Storage<br /><ul><li>Storage devices may be either above or below ground
  12. 12. Different types include
  13. 13. Storage Tanks
  14. 14. Water Containers
  15. 15. Lagoons or Lined Ponds
  16. 16. Size based on rainfall pattern, demand, budget and area</li></li></ul><li>.ppt (8)<br />Establishing the need in India…<br />A news article says that ground water levels in New Delhi are falling and RWH will become mandatory.<br />
  17. 17. .ppt (9)<br />SO AS WE ALL ARE THE HUMAN BEINGS <br />AND ITS OUR RESPONSIBILTY TO SAVE OUR GROUND WATER LEVEL <br /> AND MAKE THEM RECHARGE AT TIME TO TIME <br /> BY RAIN WATER HARVESTING<br />
