rainwater recycling

A system collecting rainwater from a structure or its grounds and routing it for use within the building.

Rainwater recycling is a green feature used in some buildings to reduce water waste. System designs may vary, but typically collect rainwater from the roof, facade, or grounds of a structure and route it into internal distribution systems.

Recycled rainwater is typically used for watering plants, flushing toilets, or other non-potable water uses.

The collected water is reused rather than simply discharged. Irrigation, toilet flushing, and other non-potable uses are typical, while the collection and distribution arrangement can vary.
