Windibri Water Treatment Plant

The Windibri Water Treatment Plant (WTP) is owned and operated by Queensland Gas Corporation (QGC), a British Gas (BG) Company and is located in the Surat Basin in Queensland, Australia. The WTP processes 6 million litres of coal seam gas waste water per day using membrane-filtration, ion exchange and reverse osmosis technology.
