Greater Southern Sydney to receive major water upgrade

Sydney Water has commenced work on a major $80 million upgrade to its Nepean Water Filtration Plant (WFP) south of Sydney. The upgrades will meet future growth demands and continue to deliver drinking water in line with Australian Drinking Water Guidelines.

Over three years, the initiative will increase water production capacity at the plant to 33 ML a day, the equivalent of 13 Olympic-sized swimming pools catering for over 50,000 people.

The Nepean Water Filtration plant is situated south of Sydney and draws from the Nepean dam. Treated water is supplied to the townships in the Wollondilly Local Government Area.

More upgrades will include a new water filtration and treatment system, including a new clarifier and dual media filters. Both process technologies will maintain the water quality.

Darren Jackson, Sydney Water Area Delivery Manager, said the upgrades will help futureproof the growth area in Sydney’s south for the next 30–40 years.

“These upgrades are part of Sydney Water’s commitment and vision to meet the needs of a growing population and continue to provide world-class water services to southern Sydney,” Jackson said.

Upgrades to the Nepean Water Filtration Plant are set to be completed by mid-2025.
