We work hard to provide as many of our customers as possible with access to safe, high-quality drinking water that consistently meets consumer and regulatory requirements in accordance with the Safe Drinking Water Act 2003 and the Safe Drinking Water Regulations 2015. The Department of Health administer the implemention of these standards across Victoria.

Our region has 18 water treatment plants that supply treated water to 89 percent of our urban customers.

  • Drinking water is safe for human consumption. It can be used for drinking, cooking, making ice, cleaning your teeth and for showering or bathing. Drinking water is filtered and disinfected to meet the strict guidelines for safe drinking water.
  • Disinfected water is in compliance with Australian drinking water guidelines but the treatment process is slightly different from other drinking water.
  • Non-drinking water isn't disinfected and isn't intended for human consumption. You can still use this water for household activities though, such as watering gardens, flushing toilets, irrigation and laundry purposes. You can also use it for showering or bathing, as long as you're careful to avoid swallowing the water.  Read about Adobe PDF file icon 24x24 Living with an untreated water supply brochure and view our Adobe PDF file icon 24x24Untreated Water Supply Notice.
