Blue-green algae (cyanobacteria) are naturally occurring bacteria which are found in the majority of waterways and storages. There are a number of different species (toxic and non-toxic) and hot weather, high nutrient levels and dry conditions can provide optimal conditions for them to flourish – rapid growth can create a ‘bloom’.

These blooms can affect water quality and Goulburn Valley Water has processes in place to ensure the continuous provision of safe and reliable water.

All drinking water supplied to customers meets the Safe Drinking Water Act 2003 and the Australian Drinking Water Guidelines. Our team is working to continually monitor and assess the water quality, and samples are regularly sent to an independent laboratory for testing. We also work closely with Goulburn-Murray Water, which manages a number of waterways from which we source water.

Regulated (non-potable) supplies

Goulburn Valley Water supplies several towns with non-potable (non-drinking) water supplies. We recommend these customers have an alternate supply of drinking water.

Potable (fully treated) supplies

We regularly monitor for any blue-green algae concentrations in our raw water supplies. Under normal circumstances, our water treatment plants are capable of removing any algae as part of the treatment process, before the water reaches your taps.
