Rain water harvesting is the indigenous water saving methods to capture every trickle of water that had fallen on land. For this we need to dig small pits and lakes, build small earthen dams, construct dykes, sand and lime stone reservoirs, set up roof top water collecting units. This will recharge ground water levels and bring rivers back to life. Water harvesting techniques give people control over their local water resources, ensures, that the mismanagement and over exploitation of these resources is reduced/removed. The advantage of water stored in the ground are many. It does not evaporate, but spreads out to recharge wells and provide moisture for vegetation over a wide area. It does not provide breeding area for mosquitoes. It is also protected from contamination by human and animal waste.
