Description

This Bulletin outlines the requirements for potable and non-potable systems and explains the specification for collection, storage, filtering and treatment.

Residential rainwater systems can provide water suitable for drinking and food preparation, if it is filtered and/or treated adequately. Water can also be used for garden irrigation, swimming pools, toilet flushing, baths and showers.
