Question

Answer 2

Rainwater harvesting

• Rainwater harvesting is the process of collecting and storing rainwater instead of letting it flow off.
• Rainwater is gathered from a ceiling surface and guided to the tank, reservoir, deepest pit, aquifers, or reservoirs through percolation, where it goes down and replenishes the groundwater levels.
• This runoff water can be kept or recycled into the underground water.
• Harvesting rainwater is the scientific and controlled collecting of rain in which it showers for later use.
