Water Treatment Plants

Part of the water treatment plant at Lake Cochran, Williamtown NSW.

Water treatment plants have been provided at some sites with the aim of reducing the amount of PFAS on Defence bases and dispersing into the surrounding area.

Construction Water Treatment Plant

Defence operated a Construction Water Treatment Plant at RAAF Base Williamtown to treat PFAS impacted ground water, encountered during construction activities.

The plant treated the water to below adopted drinking water criteria prior to it being discharged either onto open grassed areas on the Base, south of the runway or via re-injection when conditions allowed.

This plant ceased operations in early 2018.

Former Fire Training Area - Williamtown

This water treatment plant was procured to treat PFAS contamination from the RAAF Base Williamtown former fire training area.

The plant extracts contaminated ground water from a field of 15 extraction bores and returns treated water to the aquifer via a sprinkler array.
