Making hay while the sun shines

India sees it all. Rains, no rains. Floods, draughts. 
So here's literally applying the proverb in the title of the article in our lives - storing rain water and using it wisely. How? Read on...

Rain water harvesting (RWH) Rain water harvesting is collection and storage of rain water that runs off from roof tops, parks, roads, open grounds, etc. This water run off can be either stored or recharged into the ground water. A rainwater harvesting systems consists of the following components:

  • catchment from where water is captured and stored or recharged
  • conveyance system that carries the water harvested from the catchment to the storage/recharge zone
  • first flush that is used to flush out the first spell of rain
  • filter used to remove pollutants
  • storage tanks and/or various recharge structures.

Why do RWH?
Rain may soon be the only source of clean water. Rainwater harvesting systems use the principle of conserving rainwater where it falls and have the following benefits:
  • Helps meet ever increasing demand of water
  • Improves quality and quantity of groundwater
  • Reduces flooding
  • Individual homes
  • Colonies 
  • Apartments 
  • Institutions
  • Schools/colleges/universities
  • Clubs
  • Hospitals
  • Industries
  • Slums
  • Everywhere

Setting up a rainwater harvesting is not difficult but requires some sort of understanding of hydrology and architecture and as a result most people find it too complicated to do it themselves. In order to make it simple and convenient for everyone to set up a rainwater harvesting system suitable for their needs, a set of ready guidelines is available on this link.
