Water Treatment Plants

ECT2 Water Treatment Plants

Defence engaged an international environmental company Emerging Compounds Treatment Technologies, known as ECT2, to provide three water treatment plants that aim to reduce the amount of PFAS on Defence bases and dispersing into the surrounding area.

Moor's Drain

The Moor's Drain Water Treatment Plant (WTP) is treating water before it leaves RAAF Base Williamtown through Moor’s Drain. The WTP was delivered via Australian military aircraft from the United States in late May 2017.

Army Avaition Centre Oakey

The Oakey Water Treatment Plant is treating contaminated groundwater on the Base and reinjecting the treated water back into the aquifer to reduce the amount of contaminated water leaving the Base.

Katherine

The Katherine Interim PFAS Water Treatment plant is treating the bore water component of Katherine's water supply. The plant has been operating since November 2017.

Lake Cochran Water Treatment Plant

The Lake Cochran Water Treatment Plant (WTP) at Williamtown NSW is currently operational as an interim activity to treat water leaving Lake Cochran, ensuring that PFAS levels are below the adopted drinking water screening criteria (HBGV). The Lake Cochran WTP was developed by Synergy Resource Management.

The recovery of PFAS chemicals involves a multi-barrier treatment process utilising a range of different technologies including activated carbon and resin. The Lake Cochran WTP will continue for the short term whilst a long term solution is developed and implemented.

Construction Water Treatment Plant

Defence operates a Construction Water Treatment Plant (WTP)at RAAF Base Williamtown.

The WTP is treating PFAS impacted ground water, which is encountered during construction activities.

The WTP treats 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 allow.

This WTP will continue operations for as long as is required to complement construction activities.

This activity forms an integral part of Defence objectives to decrease contamination levels.
