The RWH system must ensure that not a drop of rainwater falling within the premises is let into the sewerage or wasted as runoff.

This can be achieved only if the method adopted within the premises satisfies the following CRITERIA:

Completeness: Both rooftop and driveway runoff water must be harvested.

Apportioning of water: To avoid OVERLOAD of any one system, leading to overflow and loss.

Proper design: Volume of water likely to FLOW through and the nature of the soil in the area should be CONSIDERED.

Maintainability: Design should incorporate features allowing for periodic MAINTENANCE of the structure.
