ProMac - critical works re-start in a few areas

Following the construction pause implemented by the NSW Government earlier this month, Sydney Water has reviewed the Prospect South to Macarthur Project (ProMac) schedule and identified critical projects that would jeopardise summer water supply in South West Sydney if further delayed.

Locations to resume

From Monday 2 August 2021, ProMac projects which will resume works within restricted Local Government Areas include:

  • Cecil Park Reservoir (Liverpool LGA)
  • Liverpool Reservoir (Liverpool LGA)
  • Pipeline in Western Sydney Parklands (Liverpool LGA)
  • Pipeline in Kemps Creek (Liverpool LGA)
  • Pipeline in Cecil Hills (Liverpool LGA)
  • Pipeline in Mount Annan (Camden LGA and Campbelltown LGA)
  • High Voltage power works in Bonnyrigg Heights (Fairfield LGA and Liverpool LGA)

Currently, the existing reservoir at Cecil Park is offline while our Contractor, Freyssinet Australia, works to upgrade the reservoir. The reservoir can only be offline in the winter months when demand for water is lower. To meet critical program milestones and ensure the reservoir is operational in time for summer we need to continue our works, deemed as critical construction.

What you need to know

Sydney Water will re-commence this work with strict COVID-19 controls in place. Only personnel that are approved to work under the latest NSW Government Guidelines will be permitted onsite. We will have a total of 10 workers attending each site each day. Our workers will travel directly from home to site and back each day and will have no interaction with the local community.

We thank the local community for their patience and cooperation while we deliver these essential works.


While urgent works continue, all crews are adhering to testing, social distancing, and mask requirements.

Sydney Water has a comprehensive process in place to ensure we are only conducting urgent works during this time - works that may cause harm to the community and environment if they are not carried out.

Members of the public can rest easy knowing that Sydney Water's frontline crews are authorised to work safely to continue delivering these essential services for their communities.
