Rain is collected from the roof into a tank or barrel, and the system includes screening and a first-flush diverter to keep out debris.
The use
Harvested rainwater is typically used for irrigation, and with treatment it can serve flushing or washing.
The separation
Any indoor use requires dedicated, marked pipes and backflow protection so it can never mix with the potable water.
