December newsletter - Cecil Hills, Liverpool, Elizabeth Hills

Sydney Water has a long-term plan to increase resilience in our network and to extend the city’s water capacity and supply. As part of the Prospect South to Macarthur (ProMac) program we have been constructing a new drinking water pipeline, reservoir and pump station at Cecil Hills to service the Liverpool area. On the same site we are constructing a re-chlorination plant (RCP) due for completion in 2024.

Whilst we do our best at Sydney Water to minimise the impact on the local community, we appreciate the work we do can impact some more than others. We thank the Cecil Hills community for your continued support, patience and cooperation while we complete this essential work, to provide clean, reliable drinking water to the community.

Liverpool, pump station update

Since our August update, our Principal Contractor, Service Stream, has completed the following works:

  • Commissioning activities to bring the new facility into operation.
  • Testing of the pumps.
  • Installation of the bioretention basin.

Service Stream have now left the site as Principal Contractor. New contractor, Ferrycarrig, is currently installing the RCP and works associated with this will continue into 2024. John Holland is also undertaking works on the northern portion of the site relating to the Sydney Water Upper South Creek Pipelines.

Fun Fact!

During construction there was 3,573 tonnes of spoil removed from the site during construction.


Restoration of the site

As ProMac work comes to an end and areas are restored, we will progressively replant to filter views of the new infrastructure and return some of the bush outlook. This work is ongoing during the construction of the re-chlorination plant. Much of this work will be dependant on species availability, weather and the appropriate seasonal planting requirements. We thank you for your patience during the restoration.

Did you know!

Once complete the new pump station is capable of delivering up to 153 mega liters of

clean drinking water to the community every day.


Re-chlorination plant

To improve the management of water quality for our customers, Sydney Water is installing a small re-chlorination plant inside the Liverpool Reservoir facility at Cecil Hills. Located towards the centre of the site, the building is made offsite and delivered as a complete unit on the back of a truck and lifted into position using a crane. In preparation for this, foundations and surrounding access roads have been constructed. This work began in September 2023 along with installation of electrical provisions and control cabling and is expected to be completed by early to mid-2024.


A re-chlorination plant automates the dosing and monitoring of chlorine into the adjacent reservoirs. The building will not be noisy when operational.

The holiday shutdown and work resumption

Work will cease on Friday 22 December 2023 and resume on Monday 8 January 2024. During the shutdown, all ProMac worksites will be regularly inspected to ensure temporary fencing and environmental controls are secure. If you are concerned about the condition of the site during this break, please notify the community team who will be on-call over this period.

Sydney Water would like to take this opportunity to wish everyone Season’s Greetings and all the best for a safe and happy holiday season.
