Question

Which among the following are sustainable solutions for the depleting groundwater level?

• A. Digging more wells
• B. Increasing the depths of existing wells
• C. Building percolation pits
• D. Building soak pits

Answer 1

Answer: (C), (D)

The correct options are
C Building percolation pits
D Building soak pits

Use of resources in such a way that they are available for future generations is called sustainable use of resources.

Percolation pits and soak pits let the surface water get absorbed into earth's surface thereby recharging earth's groundwater. Therefore, building percolation pits and soak pits is a sustainable solution.

Digging of more wells or increasing the depth of existing wells, will result in usage of more water from an already depleting resource.
