Nepean Water Filtration Plant

Sydney Water has begun work on an $80 million upgrade to its Nepean Water Filtration Plant, located south of Sydney. 

The upgrades over three years will meet future growth demands and continue to deliver world-class drinking water in line with Australian Drinking Water Guidelines.

The initiative will increase water production capacity at the plant to 33ML a day. It’s the equivalent of 13 Olympic-sized swimming pools catering for more than 50,000 people.

Sydney Water Area Delivery Manager, Darren Jackson, said the upgrades will help future-proof the rapidly expanding growth area in Sydney’s south for the next 30 to 40 years, as well as increase the supply of precious drinking water.

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

Situated south of Sydney, the Nepean Water Filtration Plant draws from the Nepean dam and treated water is supplied to the townships in the Wollondilly Local Government Area.

Upgrades to the plant include a new water filtration and treatment system including a new clarifier and dual media filters. Both process technologies are used to maintain the quality of water.

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