Question

Percolation tank is the storage of water for
A. Domestic purpose
B. Industrial area
C. Irrigation
D. Both A and C

Answer 1

Hint: Water is being wasted in a huge quantity so the time is near when there will be a scarcity of it. Various smart methods are being opted by the people to reuse the wastewater. The main source of potable water is groundwater and rain.

Complete answer:
Water covers 71 percent of our land. All of the water is not useful for us. So we have a limited supply of water. We get most of the water by rain, groundwater, ponds, rivers etc. So there is a need to save water to avoid any kind of water crisis.
Rainwater harvesting techniques are used to save the water from any kind of wastage. People have been smart enough to use the dirty water for irrigation, watering plants at home etc.
Percolation tanks are also one of the rainwater harvesting methods. In this, we can percolate the excess water collected into the ground to maintain the groundwater level. This is done on a highly permeable land. Recharging of the groundwater is essential. Let's read out what are the benefits of this process.
> Option A – Domestic purpose: After making a percolation tank, we can construct borewells to utilize this water for our household works.
> Option B – Industrial area: An industry needs water in a huge bulk which cannot be supplied through percolation tanks. So in the industrial area, it is of no use.
> Option C – Irrigation: Canals are constructed by the farmers to irrigate their cultivating crops. Canals are artificial waterways created by humans to get access to water. The water in them can be obtained from the groundwater through motors.
> So, we can see that our answer is option D: both A and C as we can use percolation tanks for storing water both for domestic and irrigation purposes.

Note: Growing more and more plants are necessary today to increase the fertility of the soil. Increased fertility will increase the permeability capacity of the soil. Thereby, percolation tanks will be more efficient in most of the areas.
