Oran Park Reservoir update | November 2024

Sydney Water has a long-term plan to increase resilience in our network and extend the city’s water capacity and supply. As part of the Prospect South to Macarthur (ProMac) program we have now completed construction of two 24 megalitre drinking water reservoirs at Oxley Ridge Cobbitty, (Oran Park Reservoirs).

The final preparations for filling the reservoirs and demobilising from site is now underway. Testing, cleaning and disinfection of the reservoirs is currently occurring on site to enable the reservoirs to be filled with clean drinking water. Minor civil and restoration work is also being undertaken around the site and will continue into 2025.

Reservoirs out of hours work - 24 / 7

From Wednesday, 4 December 2024 to Friday, 20 December 2024 we will commence filling the two reservoirs. Filling will be assisted by the booster pump located on the corner of The Northern Road and Brunsdon Road, Cobbitty (corner of Oxley Ridge Estate.)

Christmas Shut Down Period Our reservoir construction team will close the reservoir site from 20 December 2024 to 5 January 2025, resuming work on 6 January 2025. No work will occur during this time.

While we do our best to minimise the impact on the community, we do appreciate the work we do can impact some more than others. We thank the Oxley Ridge and Oran Park communities for your patience and cooperation as we build this critical infrastructure.

We take this opportunity to wish all of the community a safe, healthy and happy holiday season.
