Question

4. How can we do rain water harvesting?

Answer 1

• The process of conserving rainwater by collecting, storing and purifying that runs off from rooftops, parks, roads, open grounds, etc. for later use is called rain water harvesting.
• Rain water can be harvested by storing the rain water for direct use.
• Rainwater gathered on the building's rooftop may be channeled to a filtration tank, from which it goes into the recharge well, via drain pipes.
• Drain pipes can be used to divert rainfall gathered in open areas to a recharge excavated well via filtration tanks.
