  RAINWATER HARVESTING One way of increasing the availability of water to overcome its shortage is rainwater harvesting The activity of collecting rainwater directly and store it in big tanks for later use, or making the rainwater percolate into ground more efficiently to recharge the groundwater, is called rainwater harvesting. Thus there are two main techniques of rainwater harvesting: (1) Collection and storage of rainwater in tanks for future use when there is scarcity of water, and (i) To make rainwater percolate into the ground more efficiently by constructing percolation pits and recharge wells so as to recharge (or replenish) groundwater. The groundwater which we take out for our use by digging wells, tube wells and installing hand pumps, comes from the rainwater which seeps into the ground naturally. Now, when too much water is drawn through wells and tube-wells for use in homes, agriculture and industry, the water level in the wells and tube-wells goes down drastically. S...
