WATER HARVESTING
N
owadays we mainly depend on secondary sources of water like dams, lakes, groundwater or rivers whilst the primary water source is rainfall. Water harvesting is the capturing of rain water, where it falls, runs-off, catchment etc. It is direct rainfall collection, this water can be stored for later use and recharged into groundwater again. Traditionally this involves harvesting the rain from a roof, the rain will collect in gutters that channel the water in downspouts and then into some storage facility or tank. In essence, water harvesting means we recognize the rain’s value and try to utilize it when it falls. The purity of the water carefully collected from the roof is one of its most amazing attribute; if properly collected, it ranks up there with distilled water for the absence of impurities.
