PJV Design Studio & Infra is also keenly active in the Rainwater harvesting projects. PJV Design Studio & Infra wants this project to be used as the second best alternative of water resources in our country. Do connect with us for a free consultation to understand the dynamics and the financial commitment towards the same.
Rainwater Harvesting is defined by Wikipedia as “the accumulation and deposition of rainwater for reuse on-site, rather than allowing it to run off.” While this definition is basic, the practice of rainwater harvesting is greatly varied from where the rainwater is collected from to how the rainwater is ultimately used.
Why rain water harvesting is important?
The collected water reduces flooding and decreases soil erosion by decreasing the likelihood of run offs during periods of heavy rainfall. This is good news for our rivers, streams, oceans and lakes, as they will be less polluted over time.
Where can rainwater be re used?
Rainwater can be used in the house to supply washing machines and toilets - and even showers and baths if you want. The rainwater is filtered and siphoned in order to clean it making it ideal as a source of non-drinking water.
What are the two advantages of rainwater harvesting?
Reduces Flooding and Erosion - For starters, it can reduce erosion around downspouts and in gardens. It can also control stormwater runoff. Rainwater doesn't produce scale and corrosion as hard water does. The collection of rainwater may reduce flooding in certain areas as well.
What are the Rainwater Harvesting (RWH) Techniques?
Surface Runoff Harvesting: Rainwater is collected into natural reservoirs or tanks, or the infiltration of surface water into subsurface aquifers before it is lost as surface runoff.
Roof-top Rainwater Harvesting (RRH): Roof-top rainwater harvesting involves diverting and recharging (or) storing part of the rainwater that falls on the roof of a house. The harvested water is directed stored into a recharge pit, which collects and slowly recharges into the groundwater storage/aquifer in that area.
Underground Tanks: These are constructed by digging into the ground and creating a space which is then cemented to reduce water infiltration. The top is also sealed, and water is obtained through pipes directed into the tank. Pumps are used to get water out. Underground tanks are wonderful for harvesting rainwater because since they are located underground where sunlight does not really penetrate, the rate of evaporation is reduced.
