Prospect South to Macarthur (ProMac)

Share on Facebook Share on Twitter Share on Linkedin Email this link

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.

    We previously notified you that we would be working on Rickard Road, Bossley Park at night from Monday 15 August 2022 to locate services that have been covered by recent roadwork. These investigation works are necessary to support the upgrade underway at Prospect Reservoir.

    To reduce the impact to nearby residents, these works have been re-scheduled to daytime. We will now complete these works between 9.30 am and 3 pm starting on Tuesday 16 August 2022, weather permitting. Refer to map overleaf.

    Traffic changes

    As we complete this work, there will be speed reductions in place along Rickard Road and Mimosa Road. All traffic will be managed on a stop-slow arrangement. Traffic controllers will safely assist pedestrians around our work zone. Driveway access will be maintained however, residents may experience minor delays while machinery moves out of the way. Motorists, cyclists and pedestrians are advised to observe all project signage and traffic control directions during construction.

  • Cecil Hills - tree planting community day with Cecil Hills Early Education and Care Centre

    Share on Facebook Share on Twitter Share on Linkedin Email this link

    Principal Contractor Diona Pty Ltd, installed 1.95 km of trunk main through Cecil Hills in 2021-2022 for our Prospect to Macarthur program (ProMac).

    One of the businesses directly impacted by these works was the Cecil Hills Early Education and Care Centre. Following extensive consultation with centre staff, Diona was able to schedule the works to occur outside of their business hours and adjust the pipe alignment to avoid a boom gate and reduce tree loss.

    At the end of June, Sydney Water Delivery Partner ACCIONA Australia and Diona returned to the centre to donate three trees. The trees were presented to centre staff and representatives from Liverpool City Council NSW parks and facilities teams.

    We then had some very keen mini helpers pull on some gloves and help plant the trees. The spotted gums will provide the centre’s backyard with some much-needed shade in the summer months.
