Rain Water Harvesting

Ground water is a very valuable economic commodity. It is recovered from wells for domestic, industrial and agricultural use. The conservation of ground water is very important because it moves from soil and many years may be required to replace hastily pumped water. Therefore, in areas where ground water is used extensively, care must be taken that no extra water is withdrawn in a year than the quantity replenished by natural process.

To avoid depletion of ground water level, the aquifers (ground water bodies) must be recharged in whichever way possible. There is an urgent need for harvesting every drop of rain water, since that is the only source of ground water.
