Rooftop Rainwater Harvesting:Need of the Hour

Rainwater harvesting consists of three basic elements — collection area (rooO, conveyance system (pipes) and storage facilities (tank or cistern). Rainwater harvesting systems need few skills and little supervision to operate. If water is to be used for drinking purpose, filtration or chlorination is required. An area of major concern is prevention of contamination of tank during construction and while it is being replenished during rainfall. Successful rainwater harvesting projects are generally associated with communities that consider water supply a priority. Policy level changes by concerned authorities can also be helpful in bringing the desired change.
