Question

Criteria for selection of site for construction of embankment type of water harvesting structures are:
(A) The site should be 0.5 km away from settlement area.
(B) The permeability of the soils in storage area should be minimum in percolation tank.
(C) The command area should be as close as possible to the dam/pond site.
(D) The downstream area should permit natural passage for safe disposal of surplus water.
Choose the correct answer from the options given below :

• A. (A), and (C) only.
• B. (B), (C) and (D) only.
• C. (A), (C) and (D) only.
• D. (B) and (D) only.

Hint:

Remember that a percolation tank's primary purpose is to let water seep down to recharge the aquifer. Therefore, soil in its bed must be highly permeable. Since statement (B) is false, eliminating any option with (B) leaves you with the correct answer.
