Question

Percolation tank is constructed to impound

• A. Runoff water
  
• B. Water vapour
• C. Purified water
• D. None of the above

Answer 1

The correct option is A Runoff water

There are different systems constructed to increase the amount of water which is present in the groundwater reserves. The percolation tanks are constructed in the land which is highly permeable. The water from the runoff which gets collected in the tank is then percolated in the ground. This system helps to recharge the groundwater system. These are one of the methods which are used for the conservation of the water resources.

Thus, the correct answer is option A.
