Question

There are ten tube-wells in a lane of fifty houses. What could be the long term impact on the water table?

Answer 1

More number of tube-well leads to deplete the groundwater table and there will be a time when there will be no water below the pipe.

• The effect on the water table depends on the replenishment of underground water.
• If the people of the fifty houses use the ten tube wells, then the water required by them is drawn from the ground.
• If these tube wells are used for a long time, then the groundwater would be reduced and the water table would go down.
• Underground water level is decreasing day by day while the total water in the seas and oceans of the world do not remain constant.
