Prospect South to Macarthur (ProMac)

Share on Facebook Share on Twitter Share on Linkedin Email this link

Under the ProMac project we are building new drinking water pipelines and infrastructure between Prospect South and Macarthur as part of Sydney Water's long-term plan to extend the city’s water capacity and supply.

ProMac will upgrade our existing water reservoirs at Liverpool, Cecil Park and Currans Hill as well as build two new reservoirs at Oran Park. This will allow for an extra 100 Megalitres of additional reservoir capacity in Western Sydney. That’s the equivalent of about 50 Olympic-sized swimming pools!

We’re also building 15 km of additional pipework, three pumping stations and upgrading our existing network to ensure growing communities in South Western Sydney have access to clean drinking water.

Sydney Water is investing in new infrastructure that will support the growing, dynamic South Western Sydney.

ProMac will help Sydney Water deliver on its vision of creating a better life with world-class water services.

    As part of the Prospect to Macarthur project (ProMac) we are replacing the reservoir in Currans Hill so that it can reliably supply water to the community for decades to come. We dismantled the existing reservoir throughout March, April and May. We plan to start demobilising from the area on 16 May 2022, weather permitting. Stage 2 construction of the new reservoir will commence later this year, weather permitting. We will provide an update to the community once this has been confirmed.

    Demobilisation works will involve:

    • removing site facilities
    • removing all remaining plant and machinery • undertaking environmental inspections.

    Construction traffic and impacts

    There will be an increase in construction traffic around Currans Hill while we demobilise. Residents can expect to see truck movements on Turner Road, Ascot Drive and Manooka Road.

    Our work hours

    • 7 am to 6 pm Monday to Friday
    • 8 am to 1 pm Saturday.

We will work in stages to disconnect and remove the existing water main within different areas of the pumping station. Once removed, there will be new pipework installed to accommodate the new pump station. This connection work will be carried out over a 72-hour period. Your wastewater or water services will not be impacted by these shutdowns.

    The location of work for the first two stages will be at the front of our site compound near The Northern Road (please see map overleaf for the location of work). You may also notice some machinery and work vehicles moving around the site during the work.

    Stage 1 connection

    The first connection will commence at 6 pm on Tuesday 17 May to 7 am Friday 20 May 2022, weather permitting.

    Stage 2 connection

    The second connection will commence at 6 pm on Tuesday 31 May to 7 am Friday 3 June 2022, weather permitting.

    We will notify you again when we are ready to complete stages 3 and 4 of the connection works.

    These works are in addition to our standard working hours.

    Standard work hours

    • 7 am to 6 pm Monday to Friday

    • 8 am to 1 pm on Saturdays.

    Construction activities include saw cutting, welding, lifting pipes / fittings and excavation activities.

    As part of the Prospect to Macarthur (ProMac) project we are replacing the reservoir in Currans Hill so that it can reliably supply water to the community for decades to come.

    We are continuing to use a crane to dismantle the reservoir wall panels. To dismantle the final row of panels at the base of the reservoir, we need to remove the grout seal. We plan to undertake this work using an excavator and small hammer attachment from Tuesday 3 May 2022. This activity will take up to four shifts to complete, weather permitting.

    The grout is embedded in a channel in the concrete foundation around the outside of the tank. To give residents respite from noise and vibration, jack hammering works will occur in three-hour blocks, with one hour breaks in between.

    This work will involve:

    • using a 5 tonne excavator with a small cylindrical hammer attachment to break away grout from concrete using elevated work platforms to dismantle the tank in sections
    • lifting sections of panels with the use of a crane
    • transporting components that can’t be re-used or recycled offsite by truck.
