Upgrading the Saline Wastewater Outfall Pipeline

Maintaining vital infrastructure

We’re replacing 18.4km of the 54km Saline Wastewater Outfall Pipeline (SWOP) between Loy Yang Power Station and McGaurans Beach.  

The SWOP is essential to the Victorian power industry. Constructed in 1983, the pipeline transports saline wastewater from power stations in the Latrobe Valley to an ocean outfall at McGaurans Beach, where it meets strict environmental regulations, before it dilutes with seawater offshore.  

Since 2010, we’ve been monitoring the condition of the pipeline and replacing sections as required to ensure it can continue to operate into the future. 

Works are expected to commence in early 2026. 

This is one of the top 10 projects in our Price Submission 2023-28.
