Recycled water release in Bannockburn

An investigation into the emergency discharge of recycled water into Bruce's Creek at Bannockburn found no adverse impact on the creek or the Barwon River.

Around 31 million litres of treated Class C recycled water was released from the Bannockburn Water Reclamation Plant to Bruce's Creek between August and November 2011 when the plant's storage lagoon reached capacity and other options had been exhausted.

The release was coordinated with and approved by EPA Victoria, subject to a range of conditions including regular inspections and sampling.

Monitoring of the receiving waters of the Barwon River showed no detectable impact on water quality during the discharge. An independent assessment by an aquatic ecologist concluded negligible or low risk to the river environment and no lasting impact on Bruce's Creek or the Barwon River.

The event has highlighted areas in which we can improve such as reviewing emergency discharge options, conducting risk assessments for inland treatment plants, and working with community interest groups.

The Bannockburn Water Reclamation Plant is currently being upgraded. An increase in the facility's treatment and storage capacity, due for completion in mid-2012, will ease pressure on the plant and cater for future growth.
