Answer 2

Answer:

Rainwater Harvesting -

Rain water harvesting or water harvesting is a process of collecting rainwater for later use .

Watertable -

The topmost level of the groundwater, where all the space between soil particles is filled with water, is called water table .

The reasons for depletion of water table are as follows :-

Increasing population -

Increasing population creates more demand of water for the construction of houses, shops, offices, roads and pavements . It decreases the open area like parks and playgrounds. This in turn decreases the seepage of rainwater into the ground. Moreover, a huge amount of water is required for the construction work . Often groundwater is used for this.

Increasing industries -

Water is used by all the industries. Water used by most of the industries is drawn from the ground .

Agricultural activities -

Farmers have to use groundwater for irrigation . Population pressure on agriculture forces increasing use of groundwater day by day . This results in depletion of water table .
