Question

Write any two advantages of storing water underground

Answer 1

1)Ground water generally does not get polluted, if it is away (at least 20 mtr.) from the sanitary works. The water gets filtered while percolating through sand & stones. Therefore groundwater remains pure and clean.

2)Since bore well is closed, no risk of getting contaminated.

3)Since it is closed no danger of children or animals falling into it.

4)Temperature of deep water remains stable. It feels cool in summer and warm in winter.

5)Since bore are deep, chances of water remaining available in summer are more.
