Water

All habitable buildings must have a water supply that:

• is potable
• is protected from contamination
• will not contaminate the system or the source
• provides appropriate facilities for personal hygiene
• provides hot water that is safe and will not cause scalding
• discharges to a wastewater system.

The water supply may be:

• a mains water supply provided by a network utility operator, or
• a rainwater storage tank supply.

Where the water source is a mains supply, the network utility operator is responsible for the water supplied to the property boundary. The property owner is then responsible for providing the pipework to bring the water into the building.

An isolating valve is required at the point of connection for maintenance and repair of the household water supply system if required.
