(i) Groundwater has served as one of the major water sources in villages as well as in cities for quite a time.

(ii) Groundwater table is the level of water collected after the seepage of water through the top layers of soil and their collection somewhere in between voids and cracks in rocks.

(iii) Due to overexploitation of the groundwater, the water table has depleted over the years. Also because of the laying down of water impervious cemented floors and roads, rain water cannot seep in and replenish the groundwater level, thus, further contributing to depletion.

(iv) The groundwater table can be replenished by letting the rain water run into the soil, by leaving small gaps of un-cemented pavements, putting restrictions on the over-usage of ground water, etc.
