Following factors are responsible for depletion of water table :
1. Increasing population – as a result of increasing population, all the facilities such as houses, shops, roads, offices, pavements etc increase to fulfill the increasing demands. This, in turn decreases the open area for seepage of water into the ground.
2. Industrialization – Most of the stages of manufacturing processes in industries require water. If the number of industries increases, then the water required by them will also increase. Therefore, increase of industries contributes to the depletion of water table.
3. Agricultural activities – India is an agricultural country and agriculture is impossible without water. The water for agriculture is mainly utilized from ground water, rain water and canal water. As there is no rainfall in many places, agriculture cannot be entirely dependent on rain water. Also, canal water is available in a few places only. Therefore, ground water is the main source of water for agricultural activities and this causes depletion of water table.
