Cecil Hills/Bonnyrigg Heights - Cowspasture Road night work from Sunday 6 March 2022
As you are aware, we are building a new water pumping station and new water pipelines within Sydney Water’s 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 this work, we need to connect new pipes to the existing network by tunnelling under Cowpasture Road. We plan to start work on Sunday, 6 March 2022, and expect to finish by the end of June 2022, weather permitting.
Our work hours
Due to busy traffic conditions during the day, we will need to do this work at night between 9.30 pm and 5 am, Sunday, Monday, Wednesday and Thursday night only. We know this is not ideal, but we’ll do everything we can to keep noise to a minimum including where possible loading materials during the day shift, using noise blankets to enclose our work area and completing the noisiest activities at the beginning of a shift.
We will also continue working extended Saturday hours, 8 am to 5 pm, with low noise impact works to be scheduled while night works are in progress. We ask that you bear with us while we get this work completed as quickly as possible.
This work will involve
- establishing a work area within the median strip on Cowpasture Road using barriers, fencing and noise blankets (see attached map for location)
- closing one southbound lane of Cowpasture Road and reducing the speed limit
- digging an exit shaft for the Cowpasture Road micro-tunnel using an excavator
- installing pipework, valves and valve pits
- use angle grinders and welding to build steel reinforced cages
- pouring concrete
- backfilling and compaction using an excavator and whacker plate
- testing and chlorination of the new pipework
- exposing the existing water main using a vacuum truck and connecting to the new main
- loading of materials from the Liverpool Reservoir site and transporting spoil back and tipping
- restoring affected areas.
