Question

What is rain water harvesting?​

Answer 1

$\large\mapsto\boxed{ \sf \green{Answer}} \:$

Rainwater harvesting is the collection and storage of rain, rather than allowing it to run off. Rainwater is collected from a roof-like surface and redirected to a tank, cistern, deep pit, aquifer, or a reservoir with percolation. Dew and fog can also be collected with nets or other tools.
