Cecil Hills - site investigation and surveying works, corner of Green Valley Road and Wilson Road

Sydney Water is working to expand our network to meet increased demands from growth in South West Sydney. As part of this work we are building a water pumping station, a reservoir and water pipelines within our Liverpool Reservoir facility in Cecil Hills to provide drinking water services for 84,000 new homes in the South West Growth Area, Western Sydney Aerotropolis Growth Area, Liverpool CBD and Menangle Park.

As part of these works, we need to use a vacuum truck to locate the existing watermain under Green Valley Road, Cecil Hills (near the corner of Wilson Road). Please refer to map for location of work. These investigation works are necessary to support planning for a new pipe valve to be installed in the roadway in 2022.

Upcoming work

Site investigation and surveying activities will begin on Monday 29 November 2021. This work will take two days to complete, weather permitting.

Traffic changes

As we complete this work, there will be speed reductions in place along Green Valley Road and Wilson Road. There will be a temporary closure of the westbound lane along Green Valley Road near the corner of Wilson Road. All traffic will share use of the eastbound lane on a stop-slow arrangement. Traffic controllers will safely assist pedestrians around our work zone.

The health and wellbeing of Sydney Water crews are our top priority. All crews are adhering to testing, social distancing, and mask wearing requirements.
