(a) Rainwater harvesting is the collection of rain water falling on land for recharging the ground water.

The structures of rain water harvesting are: Khadin, Tanks, Kulhs, Ponds, Eris, Tals and Kattas.

(b) The various advantages of water stored in the ground are:

  1. The water stored in ground does not evaporate.
  2. The water stored in the ground spreads out to recharge wells and provide moisture for crops over a wide area.
  3. The water stored in ground does not promote breeding of mosquitoes.
  4. The water stored in ground is protected from contamination by human and animal wastes.
  5. The water stored in ground is utilised for the benefit of local population.
