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.

    Work on the ProMac Link began ahead of schedule with the first piece of the 15km long pipeline going into the ground.

    Our deliver contractors are building 750 meter of pipeline along the boundaries of Western Sydney Parklands and Sydney International Shooting Centre.

    The Shooting Centre remains open for its visitors, but the overflow carpark will be closed, and there will be increased construction vehicle traffic on site and on Range Rd.

    The Mountain Bike Track 'Wylde Park' will still be open, but some parts of the trail will be closed during construction to ensure safety of the community. For the latest updates on the track closure, please visit Western Sydney Parkland Wylde website

    The proposed pipeline route between Liverpool and Cecil Park reservoirs

    Liverpool reservoir

    As part of ProMac we’re upgrading existing drinking water infrastructure at the Liverpool and Cecil Park reservoir sites. A new reservoir tank and water pumping station will be added to the site at Liverpool, with a new pipeline connecting the two reservoirs. These upgrades will provide resilience to the local community by

    The proposed route of the pipeline between Liverpool and Cecil Park follows existing roads and public reserve land. To help in the development of our designs, we’re completing geotechnical and survey site investigations in the area. Some private landowners will be contacted to allow us to investigate existing stormwater drains and sewer maintenance holes on their property to allow our design to accommodate these existing services.

    We’ve started constructing the new Liverpool reservoir with our contractors preparing the site for the new water tank. We’re finishing the design of the underground pipeline in discussion with the needs of Liverpool City Council, Western Sydney Parklands, Westlink M7 and Transport for NSW.

    Construction of the Liverpool reservoir to Cecil Park reservoir pipeline is expected to start in December 2020.
