Under the ProMac project we are building new drinking water pipelines and infrastructure between Prospect South and Macarthur as part of Sydney Water's long-term plan to extend the city’s water capacity and supply.

ProMac will upgrade our existing water reservoirs at Liverpool, Cecil Park and Currans Hill as well as build two new reservoirs at Oran Park. This will allow for an extra 100 Megalitres of additional reservoir capacity in Western Sydney. That’s the equivalent of about 50 Olympic-sized swimming pools!

We’re also building 15 km of additional pipework, three pumping stations and upgrading our existing network to ensure growing communities in South Western Sydney have access to clean drinking water.

Sydney Water is investing in new infrastructure that will support the growing, dynamic South Western Sydney.

ProMac will help Sydney Water deliver on its vision of creating a better life with world-class water services.

    As part of ProMac, we are building a new water pumping station at the Liverpool Reservoir facility in Cecil Hills.

    Since our April newsletter update, we have completed pre-commissioning activities for the pumping station. This involved testing of pumps, fans and motors inside the pumping station, as well as pressure testing and disinfection of the newly installed pipe work.

    Upcoming work

    We are now ready to start commissioning activities to bring the new facility into operation. This work will be completed over 12 weeks from Monday 8 May 2023.

    This work will involve:

    • disinfecting and flushing pipework at the new pumping station facility
    • connecting the new pumping station to the live Sydney Water network
    • pumping water from the new Cecil Hills pumping station to the Bonnyrigg and Cecil Park Reservoirs intermittently throughout the day.

    Once the facility is operational, the pumps will facilitate water flow day and night, intermittently. The pumping station is lined with sound absorbing material and when commissioning is complete, a door will be installed on the pumping station to further minimise operational noise.

    What you need to know

    There will be no interruptions to your water services while we complete this work. All work associated with the new reservoir, pumping station and pipework will not affect the supply of water pressure to your property.

    In Cecil Hills, we installed 1.95km of new water main. As part of this work, we installed a valve in the grass verge along Prince Close in 2021 to control water flow across the Sydney Water network. In February 2023, we completed critical maintenance work on the valve. Investigation work determined that the valve will need to be replaced.

    Upcoming work

    From Monday 1 May 2023, we will return to the same location to complete a full replacement of the valve. This work will take up to two weeks to complete, followed by a further one week of testing and commissioning, weather permitting. Please see map overleaf for the location of work.

    There will be no interruptions to your driveway access or water service during this work.

    Traffic changes

    As we complete this work, traffic control will be used to assist with the management of traffic, however no road closures are planned along Prince Close. A small crew of workers will park on the grass verge off the corner of Prince Close and Sandringham Drive. Refer to map for location of parking.
