Write a short note on water conservation.

Explanation

Water conservation is the preservation, control and management of water resources.
Industrial conservation
Water conservation measures that can be taken by industries are:
* using dry cooling systems.
* if water is used as cooling agent, reusing the water for irrigation or other purposes.
Agricultural conservation
Agricultural water is often lost due to leaks in canals, run off and evaporation. Some of the water conserving methods are:
* using lined or covered canals that reduce loss of water and evaporation.
* using improved techniques such as sprinklers and drip irrigation.
* encouraging the development of crops that require less water and are drought resistant.
* mulching of soil in vegetable cultivation and in horticulture..
