We manage water quality in our region so that current and future customers can enjoy safe, affordable and accessible water.

Water quality

We have many different Water Treatment Processes (PDF 61KB). The Safe Drinking Water Act 2003 specifies drinking water quality standards in Victoria. Compliance with water quality standards is our Safe Drinking Water Act 2003 Annual Report (PDF 11MB).

The Australian Drinking Water Guidelines (ADWG) are also used by the water industry as a guide to what makes good quality drinking water.

Customer Charters

Our ongoing responsibilities and commitment to our customers are reflected in our Customer Charters:

Our Charters are based on the Essential Services Commission's (ESC) Customer Service Code Urban Water Businesses.

The ESC also regulates our fees and charges.

Wastewater treatment

We treat sewage and wastewater at different treatment plants throughout our region.

The Environment Protection Authority's (EPA) Code of Practice for Onsite Wastewater Management specifies how we need to manage emissions, including wastewater quality and odour.

Our EPA Licence (PDF 13 MB) allows us to reuse treated wastewater according to Victorian Government conditions.
