Rain Water Harvesting

Water Conservation

• Important step for solutions to issues of water and environmental conservation is to change people's attitudes and habits
• Conserve water because it is right thing to do!. 
• 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.
• 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 RWH- process of collecting, conveying & storing water from rainfall in an area – for beneficial use.
•  Storage – in tanks, reservoirs, underground storage- groundwater
•  Hydrological Cycle


• RWH - yield copious 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 m2), post-evaporation.
• As RWH - neither energy-intensive nor labour-intensive
• It can be a cost-effective alternative to other water-accruing methods.
•  With the water table falling rapidly, & concrete surfaces and landfill dumps taking the place of water bodies, RWH is the most reliable solution for augmenting groundwater level to attain self-sufficiency

RWH – Methodologies

• Roof Rain Water Harvesting
• Land based Rain Water Harvesting
• Watershed based Rain Water harvesting
• For Urban & Industrial Environment –
• Roof & Land based RWH
• Public, Private, Office & Industrial buildings
• Pavements, Lawns, Gardens & other open  spaces

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
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 only relief
8. In saline or coastal areas & Islands, rain water provides good quality water
