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 and Cecil Park 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 the Prospect to Macarthur (ProMac) project we are upgrading the existing reservoirs at Liverpool and Cecil Park as well as building two new reservoirs at Oran Park to allow for a total of 100 ML of additional reservoir capacity.

    As part of these works, we will be installing an air valve on the corner of Twenty Fifth Avenue and Twenty Sixth Avenue in West Hoxton which will release any built-up air in the drinking water pipeline. This air valve will ensure the performance of the pipe is maintained. Works will begin on Monday 18 October 2021, expected to finish by the end of October 2021, weather permitting. There will be an interruption to water supply during the final stages of work. Residents will be notified before this occurs.

    Work will involve:

  • Kemps Creek - cathodic protection installation

    We are installing 26 cathodic protection pits and test points along the verge of Cross Street and Western Road. Cathodic protection is a system used to extend the life of the steel water main by minimising corrosion of the pipe. This requires installing sacrificial metals (anodes) alongside the pipeline which corrode at a faster rate than the steel main. These anodes are attached to the pipe with cables which lead up to an above-ground test point mounted on a pole and a cabinet (see image below).

    The work will be happening in localised areas between Monday 11 October and Saturday 30 October 2021, weather permitting.

    Traffic changes

    During the works there will be changes to traffic conditions on Cross Street and Western Road. Lane closures and traffic control will be in place to safely assist motorists around our work areas. Please see map below for location of work.
