A $13.7 million upgrade to Prospect Dam has been completed to boost Sydney’s water security.

“I am very pleased to announce that the upgrade and improvements to Prospect Dam that began in October last year have been completed, on schedule and on budget,” said NSW Minister for Natural Resources, Lands and Water Kevin Humphries.

Prospect Dam is an integral part of Sydney’s water supply system and for the past 125 years has helped provide residents of Sydney with a continuous and dependable water supply.

The upgrade included reshaping work along the crest of the dam and the dam wall, as well as improvements to the sand filter within the dam wall and will allow Water NSW to continue to source the best quality water available to send to homes and businesses across Sydney.

This range of works is one of the most significant upgrades to Prospect Dam since the Upper Nepean water supply system was completed in 1888.

Member for Smithfield Andrew Rohan said Prospect Dam was Australia’s first earth fill dam and was designed as the centrepiece of the Upper Nepean Scheme to provide Sydney with water collected south of the city.

Prospect Reservoir is an important part of Sydney’s back-up water supply and plays an important role in ensuring we continue to supply the highest quality water possible to the people of Sydney, Mr Rohan said.

These improvements were undertaken as part of Water NSW’s ongoing works program to ensure that all of our dams are structurally sound, well maintained and meet customers’ needs into the future.

This work will ensure that Prospect Dam remains secure and reliable for many years to come.
