Answer 2

Rain water harvesting is a technique used for collecting, staring and using rain water for landscape irrigation and other uses. Water flows in a tube that leads to a staring tank. The water goes into the storage tank. Water goes to sand filter and to clean the rainwater.

After sand filtering it goes to the main tank. The rainwater goes to the pumping system so it can pump the water up. Then the water goes to the tank in the cellar , so from the cellar to the building. Then we can use the rain water to drink , take bath, etc.
