Rainwater harvesting (civil engineering seminar)

  1. 1. A SEMINAR PRESENTATION RAINWATER HARVESTING ON IMLIMEREN LONGCHAR SUBMITTED BY
  2. 2. RAIN WATER HARVESTING
  3. 3. WHAT IS HARVESTING?  Harvesting is defined as storing in such a way that it can be used throughout the year.
  4. 4. WHAT IS RAIN WATER HARVESTING?  Rainwater harvesting is the accumulating and storing of rainwater by artificial methods for further utilization.  The principle of collecting and using precipitation from a catchments surface.  Mostly done by rooftop harvesting and is used for domestic and agricultural purposes.
  5. 5. WHY IS THIS REQUIRED?  Surface water is inadequate to meet our demand and we have to depend on ground water.  Environmental Changes.  To arrest ground water decline and augment ground water table  To beneficiate water quality in aquifers  To conserve surface water runoff during monsoon  To reduce soil erosion  Due to rapid urbanization, infiltration of rain water into the sub- soil has decreased drastically and recharging of ground water has diminished etc.  Bangalore gets most of its drinking water from a distance of 95 kms. and a depth of 500 mts.
  6. 6. RAIN WATER HARVESTING TECHNIQUES :  Roof top rainwater harvesting.  Surface runoff harvesting .
  7. 7. COMPONENTS OF ROOFTOP RWH  CATCHMENT  COUNDUITS  FILTERS  STORAGE FACILITY
  8. 8. A first rain separator and a sand filter (First Flush)
  9. 9. EVERY ROOF IN A CITY CAN BE A CATCHMENT
  10. 10. SURFACE RUNOFF HARVESTING  Harvesting of surface runoff and storage of the same into reservoirs such as water pans makes it available for use when required.  In this method of collecting rainwater for irrigation, water flowing along the ground during the rains will be collected to a tank below the surface of the ground..
  11. 11. USES OF RAINWATER HARVESTING  Domestic Use  Agricultural Use  Industrial and Commercial use  Increase groundwater supplies
  12. 12. Advantages:  It provides self-sufficiency to water supply.  Rainwater harvesting is less expensive, easy to construct and easy to maintain.  Rainwater Harvesting slows down water flow, contains potential floodwater and reduces spread of pollution.  The water is convenient and accessible; valuable time and effort are saved in collecting and/or hauling water.  It provides a supply of water to meet our future needs.
  13. 13. Disadvantages:  Initial cost may be high.  Regular Maintenance .  Vulnerable water quality.  Storage capacity limits.
  14. 14. CONCLUSION  On of the best way to solve the world burning facing issue: Water Scarcity.  Most useful for large scale applications.  Saving of energy per lifting of well and saving of Water bills.  Harvested water can be used for Daily household needs.  The more the business and industries involved = greater environmental and economic benefits.  Rainwater Harvesting saves water, money and the environment.
  15. 15. Rainwater Harvesting A NOBLE GOAL A COMMON RESPONSIBILITY
