Non-drinking water


The majority of water supplied by Wannon Water is drinking water and meets the requirements of the Safe Drinking Water Act 2003.

Wannon Water also supplies non-drinking water to a number of customers under "supply-by-agreement" contracts. This water is not intended for drinking and should not be mistaken as drinking water. Water supplies that are not intended for human consumption, but could be mistaken as drinking water, are declared "regulated water" supplies by the Minister for Health. Advice and zones regarded as regulated water are given below.
