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.
These works are essential as the pipeline is critical to ensure the Victorian power industry can continue to generate electricity.
The sections of pipeline we’re replacing are ageing and at risk of breaking. By undertaking these works now, there’s less chance a break in this pipeline would result in a spill of wastewater to the environment.
Works are underway and expected to be complete by 2028 or 2029 .
This is the largest of our major project in our Price Submission 2023-28.
