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.

Frequently Asked Questions

Q. What infrastructure is required for the ProMac project ?

The following existing infrastructure will be utilised:

  • Pipeline between Prospect WFP and Liverpool
  • Reservoir at Liverpool 
  • Reservoir at Cecil Park 
  • Pipeline along the Northern Road
  • Pipeline from Oran Park to Narellan South
  • Reservoir at Narellan South

Q. What area does the ProMac supply?

In addition to improving service to existing customers, the project will support growth in South West Sydney Growth Area, Western Sydney Aerotropolis, Liverpool CBD and Menangle Park.

Q. What’s the current state?

Currently, Sydney’s Macarthur-Camden area is supplied by water from the Metro Dams and Warragamba Dam.

Kemps Creek, Bringelly, and Rossmore areas currently have very minimal water infrastructure including tanks, rainwater, and farm-dam water.
The additional infrastructure will provide more storage capacity for drinking water to support growth and development within these areas, manage supply and account for future growth.


Q. How will you be engaging the community?

Regular work notifications and newsletters are delivered to residents and businesses to keep them informed of our progress and possible impacts. The community team also regularly door knocks residents who will be directly impacted by upcoming work to explain the impacts and understand if the project team is able to address specific concerns.

 Residents are also encouraged to contact the ProMac community team to provide feedback and ask questions.


Q. How are you working with other agencies to ensure this is delivered on time and on budget?

The construction ProMac pipeline and other assets such as chlorination plants and pump stations have implications for utility assets and land-use.

We have engaged with Local Councils, Endeavour Energy, TransGrid, AGL, APA, Jemena, major developers, private property owners, Western Sydney Parklands Trust, National Parks, Australian Botanic Garden and Water NSW to ensure that the project is coordinated with other activities and infrastructure projects. 

We are working particularly closely with Transport for NSW to coordinate our works with the M12 and Elizabeth Drive upgrade projects.


What hours can construction activity occur?

ProMac's standard construction hours are 7am to 6pm Monday to Friday and 8am to 1pm Saturday.

Where possible, we do not work on Sundays or public holidays.

We may work outside of these hours from time to time, but we will always notify you before this occurs.

  

Q. Why is access restricted through Western Sydney Parklands (WSP)?

From Thursday 11 February 2021 until November 2021 the southern pedestrian bridge over the M7 into Western Sydney Parklands will be closed.

Some pathways inside the Parklands will also be closed for this period.

These changes are necessary to ensure park users are kept away from heavy machinery that will be used to build the new pipeline in WSP.

Signage has been installed to direct park users around path closures.

 We appreciate the Parkland's tracks are well utilised and we apologise for the disruption caused by this temporary change to access.
