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.

    Sydney Water has been working to expand our network to meet increased demands from growth in Southwest Sydney, ensuring our existing and future customers continue to have reliable access to clean drinking water.

    To service the ongoing development within Western Sydney including the Western Sydney Airport (WSA), a new drinking water pipeline has now been laid from Western Road through Overett Avenue, Kemps Creek. The pipeline crossed under South Creek continuing up to and along Martin Road, crossing Elizabeth Drive onto the WSA site at Badgerys Creek.

    Some additional construction work along Elizabeth Drive is still being undertaken. Particularly that of a valve arrangement near the intersection of Elizabeth Drive and Badgerys Creek Road, there will be no disruption to road users. Remaining work along Martin Road is also nearing completion with temporary restoration work planned before the shutdown on Friday 20th December 2024.

    Sydney Water has a long-term plan to increase resilience in our network and extend the city’s water capacity and supply. As part of the Prospect South to Macarthur (ProMac) program, since 2020 Sydney Water have constructed 22km of water trunk mains, 3 pump stations, 4 new reservoirs, 5 rechlorination plants (RCP) and rebuilt the reservoir at Currans Hill.

    We are pleased to advise the 6 megalitre reservoir project at Currans Hill is complete and now in operation, providing essential drinking water to the Macarthur community. Our contractors have demobilised from the site with only minor restoration work around the site to continue in November and December, followed by general maintenance.

    Sydney Water and its contractors extend their heartfelt thanks to the Currans Hill community for your patience and cooperation during this crucial project, especially to those residents on Manooka Road. We also appreciate the broader Currans Hill community residing on the route taken for the delivery of the stair tower, and the out-of-hours work that was necessary.

    We recognise the inconvenience these operations can cause and are grateful for your support. Sydney Water would like to take this opportunity to wish you and your families well for the upcoming festive season and new year.

    Stay safe and be water wise.

    Sydney Water has a long-term plan to increase resilience in our network and extend the city’s water capacity and supply. As part of the Prospect South to Macarthur (ProMac) program we have now completed construction of two 24 megalitre drinking water reservoirs at Oxley Ridge Cobbitty, (Oran Park Reservoirs).

    The final preparations for filling the reservoirs and demobilising from site is now underway. Testing, cleaning and disinfection of the reservoirs is currently occurring on site to enable the reservoirs to be filled with clean drinking water. Minor civil and restoration work is also being undertaken around the site and will continue into 2025.

    Reservoirs out of hours work - 24 / 7

    From Wednesday, 4 December 2024 to Friday, 20 December 2024 we will commence filling the two reservoirs. Filling will be assisted by the booster pump located on the corner of The Northern Road and Brunsdon Road, Cobbitty (corner of Oxley Ridge Estate.)

    Christmas Shut Down Period Our reservoir construction team will close the reservoir site from 20 December 2024 to 5 January 2025, resuming work on 6 January 2025. No work will occur during this time.

    While we do our best to minimise the impact on the community, we do appreciate the work we do can impact some more than others. We thank the Oxley Ridge and Oran Park communities for your patience and cooperation as we build this critical infrastructure.

    We take this opportunity to wish all of the community a safe, healthy and happy holiday season.

    Sydney Water Corporation (Sydney Water) is working to expand our network to meet increased demands from growth in South West Sydney, ensuring our existing and future customers continue to have reliable access to clean drinking water.

    To service the ongoing development within Western Sydney including the Western Sydney Airport (WSA), a new trunk water main is being constructed from Western Road, along Overett Avenue under South Creek to Martin Road and onto the WSA site at Badgerys Creek, along Elizabeth Drive.

    Work is about to commence on the eastern verge of Martin Road, near the intersection of Elizabeth Drive at 10 Martin Road. This will involve the construction of a microtunnel pit. To avoid road closures and maximise the safety of our construction team we will be working nights and all-day Saturday and Sunday this week.

    Upcoming work - out of hours.

    Monday 19 August to Saturday 24 August 9pm–5am (Night crew)

    Saturday 24 August and Sunday 25 August. 7am–8pm (Day crew)

    Our standard work hours are:

    Monday to Friday 7am - 6pm

    Saturday 8am - 1pm

    This work will involve:

    • Construction of the microtunnel receival pit.

  • Currans Hill Reservoir update

    Further to our notification in July, we can now confirm the four sections of the stair tower for the Currans Hill Reservoir will arrive on Monday 19 August at 5am.

    As the stair tower is ‘oversize’, two 40 foot semi-trailers are required to deliver it to site outside peak hours to minimise impacts on traffic. Four ‘wide load’ escort vehicles will also accompany the semi- trailers.

    An approved traffic route issued by Camden Council is included for your reference. All appropriate out of hours permits have been lodged and approved by Transport for NSW and Sydney Water.

    We ask all residents who live on the approved route to consider the following on Sunday (18 August) night:

    • Avoid street parking where possible.

    • Street parking should avoid vehicles parking opposite (parallel) another vehicle. As mentioned, the two trucks are wide loads, two vehicles parked on either side of the road will prevent the trucks access. Please stagger vehicles or park on the same side of the road. Particularly those residents in Manooka Road.

    Out of Hours delivery:

    • The complexities of this delivery requires an out of hours delivery to site in Manooka Road at 5am. Residents in Manooka Road may notice some noise associated with the trucks arrival and delivery to site. We will do our best to minimise noise and light disturbances.

    • Site managers will be placing traffic cones where possible along the route on Sunday evening to avoid cars parking in those areas. Please do not remove these cones and make alternative arrangements to park your vehicle.

    Where do I get more information and help?

    If you would like to know more, please contact our community engagement team on 1800 678098, email us at ProMac@sydneywater.com.au or visit sydneywatertalk.com.au\ProMac.. For 24-hour service difficulties or emergencies, please call Sydney Water on 13 20 90.

    Sydney Water is working to expand our network to meet increased demands from growth in South West Sydney, ensuring our existing and future customers continue to have reliable access to clean drinking water.

    As part of the Prospect to Macarthur (ProMac) project we have been replacing the old reservoir (off Manooka Road) in Currans Hill, including associated pipework and connections so that it may reliably supply water to the community for decades to come.

    We are pleased to advise work at the Currans Hill reservoir is nearing completion. The painting and blasting of the reservoir is finished, as are civil works required for the installation of the stair tower.

    The next major milestone is the delivery of the stair tower. This will arrive on a 40 foot semi-trailer across four separate deliveries. The stair tower will be “oversize” on the semi-trailer so will have a “wide load” escort vehicle accompanying it. This will occur the week beginning 22 July until mid August 2024. Specific dates and times are to be confirmed, this notice is to inform the community in advance and to advise you there may be further information with short notice.

    An approved traffic route issued by Camden Council is included for your reference.

    We encourage those residents who live on this route to consider the following:

    • Avoid street parking where possible.
    • Any street parking should avoid parking opposite (parallel) another vehicle. The truck is a wide load, two vehicles parked on either side of the road may prevent the trucks access. Please stagger vehicles or park on the same side of the road.
    • Those residents on the transport route please register your email with us (ProMac@sydneywater.com.au) to allow us to provide more information on times and dates of this delivery.

    Our standard work hours:

    • 7:00 am to 6:00 pm Monday to Friday
    • 8:00 am to 1:00 pm Saturday. We will not work public holidays.

    Out of Hours delivery:

    • The complexities of this delivery may require out of hours delivery to site. We will inform residents on the transport route more details in the coming weeks if this is required.
