Question
What is water harvesting? Write any two advantages of it.

Answer

Rain water harvesting is a technique used for collecting, storing and using rainwater for landscape, irrigation and other uses. Rain water is collected from various hard surfaces such as roof tops and other man-made above ground surfaces.Advantages of water harvesting:
  • Water collected in ground does not evaporate, but spreads out to recharge wells and provides moisture for vegetation over a wide area.
  • The groundwater is also relatively protected from contamination by human and animal waste.
  • It provides year round supply of drinking water.
  • It does not provide breeding grounds for mosquitoes like stagnant water collected in ponds or artificial lakes.
