Groundwater depletion and ways for its replenishment:

Groundwater depletion is defined as long-term water-level decline caused by sustained groundwater pumping. The volume of ground water in storage is decreasing in many areas of the world in response to pumping. Some of the negative effects of groundwater depletion include increased pumping costs, deterioration of water quality, reduction of water in streams and lakes.

Some ways for water replenishment are:

(i) Reduction in consumption: Sprinkler and subsurface irrigation techniques reduce the amount of water used in irrigation.

(ii) Rain water harvesting: Rain water collected over roofs is allowed to pass into the ground through deep water pipes.
