Prospect South to Macarthur (ProMac)

As part of the Prospect to Macarthur (ProMac) program we are building a new water pumping station and new water pipelines within our Liverpool Reservoir facility to provide drinking water services for 84,000 new homes in the South West Growth Area and Western Sydney Aerotropolis Growth Area.

The contractor has completed the installation of all civil, electrical and mechanical work at the Liverpool Reservoir site in preparation for the final stages of construction. The final stages of work will commence from Monday 10 July 2023, weather permitting.

To meet critical project milestones, we will be working extended Saturday hours from 8 am to 5 pm from Saturday 15 July until 30 September 2023 (refer to map overleaf for location of work).

Location of work

Construction of the new water pumping station inside the Liverpool Reservoir facility is nearly complete. We are currently completing commissioning activities to bring the facility into operation.

As part of the work, we need to decommission the existing Bonnyrigg Water Pumping Station along Cowpasture Road, between Cecil Hills and Green Valley. This work will take 16 weeks to complete between Saturday 15 July and Monday 30 October 2023, weather permitting.

We will notify you if there will be interruption to your water supply.

This work will involve

• work inside the Bonnyrigg Pump Station within standard work hours
• excavations along council verge on the west end of Rodeo Drive within standard work hours
• excavations parallel to Cowpasture Road outside of standard work hours at night
• commissioning works on Rodeo Drive outside of standard work hours at night
• installation of new electrical cables
• restoration of all impacted areas.

Location of work

As part of ProMac we are building a new water pumping station at the Liverpool Reservoir facility in Cecil Hills.

Upcoming work

We are currently undertaking commissioning activities to bring the new pump station into operation. As part of this work, we have been testing the newly installed pumps inside the facility. A portion of this testing will need to be completed at night between 9 pm to 7 am from Monday 5 June to Friday 9 June 2023.

There will be minimal noise impacts and no interruptions to your water services while we complete this work.

This work will involve

• flushing water through newly installed pumps outside of standard work hours (refer to map overleaf for location of testing)
• monitoring noise output
• operating lights at the site outside of standard work hours
• vehicle and worker movements around the site outside of standard work hours.

Standard work hours

• 7 am to 6 pm Monday to Friday
• 8 am to 1 pm Saturday. We will not work on Sundays or Public Holidays.

Location of work

We are building a new re-chlorination plant at our Narellan South Reservoir site at Mount Annan, to improve the management of water quality for our customers.

Upcoming work

The re-chlorination plant has been built off site and is now ready to be delivered in three units. A crane will arrive to site during standard work hours on Monday 15 May 2023.

Due to busy road conditions during the day, we will need to transport the re-chlorination plant units outside of standard work hours. The units will be transported to site using three heavy vehicles on Tuesday 16 May 2023 between 2 am and 7 am, weather permitting.

The heavy vehicles will park on site with the delivery until work can commence during our standard construction hours.

Our standard work hours

• 7 am to 6 pm Monday to Friday
• 8 am to 1 pm Saturday. We will not work on Sunday or Public Holidays.

This work will involve:

• a crane mobilising to the site during standard construction hours
• multiple oversized construction vehicles entering the site outside of standard construction hours
• unloading the re-chlorination plant using a crane during standard construction hours.

Construction traffic and impacts

There will be an increase in construction traffic around Mount Annan during this activity (refer to map overleaf). Residents can expect to see truck and crane movements along Mount Annan Drive, Swansona Avenue, Commelina Drive, Moyengully Avenue and Indigofera Circuit (northern access route).

Location of work

As part of foundation works in preparation for construction of the new Oran Park Reservoirs, our contractor Vaughan Civil has completed site establishment and commenced concrete piling.

Upcoming work

Extended weekend hours will occur from Saturday 6 May 2023 until 30 September 2023 to complete piling and concrete works. Refer to map overleaf for location of work.

As works progress, we may need to complete night work. We will notify you before this occurs.

Extended weekend hours

• 7 am to 6 pm Saturday and Sunday. These hours are additional to our standard work hours.

Standard work hours

• 7 am to 6 pm Monday to Friday
• 8 am to 1 pm Saturday. We will not work on Public Holidays.

Construction traffic and impacts

Heavy vehicles will enter the site via our northern access road (off The Northern Road). Heavy vehicles will exit the site via our southern access road (off Brundson road). Refer to map overleaf.

Location of work

As part of ProMac, we are building a new water pumping station at the Liverpool Reservoir facility in Cecil Hills.

Since our April newsletter update, we have completed pre-commissioning activities for the pumping station. This involved testing of pumps, fans and motors inside the pumping station, as well as pressure testing and disinfection of the newly installed pipe work.

Upcoming work

We are now ready to start commissioning activities to bring the new facility into operation. This work will be completed over 12 weeks from Monday 8 May 2023.

This work will involve:

• disinfecting and flushing pipework at the new pumping station facility
• connecting the new pumping station to the live Sydney Water network
• pumping water from the new Cecil Hills pumping station to the Bonnyrigg and Cecil Park Reservoirs intermittently throughout the day.

Once the facility is operational, the pumps will facilitate water flow day and night, intermittently. The pumping station is lined with sound absorbing material and when commissioning is complete, a door will be installed on the pumping station to further minimise operational noise.

What you need to know

There will be no interruptions to your water services while we complete this work. All work associated with the new reservoir, pumping station and pipework will not affect the supply of water pressure to your property.

Location of work

In Cecil Hills, we installed 1.95km of new water main. As part of this work, we installed a valve in the grass verge along Prince Close in 2021 to control water flow across the Sydney Water network. In February 2023, we completed critical maintenance work on the valve. Investigation work determined that the valve will need to be replaced.

Upcoming work

From Monday 1 May 2023, we will return to the same location to complete a full replacement of the valve. This work will take up to two weeks to complete, followed by a further one week of testing and commissioning, weather permitting. Please see map overleaf for the location of work.

There will be no interruptions to your driveway access or water service during this work.

Traffic changes

As we complete this work, traffic control will be used to assist with the management of traffic, however no road closures are planned along Prince Close. A small crew of workers will park on the grass verge off the corner of Prince Close and Sandringham Drive. Refer to map for location of parking.

Thank you for your cooperation and patience during this essential work.
