Water supply

How we keep your drinking water safe

Water treatment

We have 14 water treatment plants which supply water to more than 75,000 properties through more than 2,000 kilometres of water mains.

The way water is treated depends on where it is sourced. We take water from aquifers (ground water), rivers, creeks and reservoirs. Our largest storage is Moondarra Reservoir, south of Erica.

We also take water from storages managed by Southern Rural Water (Blue Rock Dam and Lake Glenmaggie) and Melbourne Water (Tarago Reservoir) to supply our customers living near these sites.

Our water is independently tested at the treatment plant, in our water mains, and at customers’ taps to ensure it meets the requirements of the Safe Drinking Water Act 2003 and doesn't deteriorate after it leaves the treatment plant. The water is tested for microbiological, chemical and physical parameters.

Water releases

The Moondarra Reservoir has a spillway that allows flood waters to spill when the storage is at full capacity. The Moondarra Reservoir doesn't have the infrastructure to pre-release water prior to flood events. We monitor storage capacity before, during and after any flood event and respond as required.

Water planning for the future - Urban Water Strategy

The Urban Water Strategy (UWS) is our principal water resources planning document. The UWS identifies what we need to do to ensure urban and industrial water availability, and sewer system capacity, in our region for the next 50 years.
