Individual Supplies
An individual household drinking water supply is a stand-alone system that is not connected to a community drinking water supply. Individual household supplies have a responsibility to produce safe drinking water as described in the Building Act 2004 and its amendments.
Safe drinking water is vital for the good health of you and your family and the people who visit your home. Water used for drinking, teeth cleaning, hand washing, bathing, showering, food preparation, and cooking needs to be free from harmful germs and chemicals. If your water comes from a water collection tank, it is up to you to keep your water safe and reduce the risk of water-borne illness from contaminated tank water. If your water comes from a mains supply, your water safety is monitored by your local authority.
