उत्तर
Rooftop rainwater harvesting is a method where rainwater is collected from the rooftop to a storage tank through pipes. This water needs to be filtered before using because it may contain some soil from the roof. Instead of collecting rainwater directly in the tank, the pipes can go directly into a pit in the ground. This then enters into the soil to recharge or refill the groundwater.
