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.

    We successfully installed and connected a valve to the water main in the laneway behind 65 Mimosa Road, Bossley Park to control the pressure of the water as it enters homes.

    We are now ready to return to site to install an electrical cabinet and connect the cabling. The cabinet will be installed on the 3 metre by 1.2 metre concrete foundation in the nature strip in front of 2 Quarry Road. We will start these works on Monday 18 July 2022 and will take up to one week to complete the installation, weather permitting. There may be 1-2 days during this week of work that we’ll need to open a pit lid in the laneway behind 65 Mimosa Road to carry out some activities.

    This work will involve:

    • trenching in the nature strip outside number 2, 4 and 6 Quarry Road
    • installing instruments in the laneway at the rear of 65 Mimosa Road shops • installing the electrical cabinet and connecting the cables
    • restoring impacted areas.

    As part of the Prospect to Macarthur (ProMac) project we are building a new re-chlorination plant within our Campbelltown South Reservoir site at Bradbury to improve the management of water quality for our customers (please see map location).

    The re-chlorination plant was being built off site and is now ready to be delivered. To do this, we will need to transport the unit outside of standard construction hours due to busy road conditions during the day. This will involve oversized construction vehicles driving into site between Wednesday 13 July and Friday 15 July from 11pm to 7am, weather permitting. The construction vehicles will park on site with the delivery until work can commence during our standard construction hours.

    Should we not be able to undertake the delivery as scheduled, we will carry out this work between Wednesday 20 July and Friday 22 July as contingency.

    Construction traffic and impacts

    There will be an increase in construction traffic around Bradbury during our work. Residents can expect to see truck movements on Karrabul Road, St Johns Road, Akuna Avenue, Greengate Road and Merino Crescent.

    Sydney Water are building a new water pumping station on The Northern Road in Harrington Park, to provide drinking water services for 84,000 new homes in the South West Growth Area and Western Sydney Aerotropolis Growth Area.

    As part of this work, we need to carry out several watermain connections over the coming months. 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. There will be trucks and other construction equipment with reversing beepers working in the area. We’ll try to do the noisiest work early in the night, but there’ll be some noise after midnight at times.

    Traffic changes

    As we complete this work, a section of the footpath along The Northern Road has been temporarily reduced to one lane. The changed pedestrian conditions will remain in place for the duration of the work.

    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 these works, we successfully installed and connected a valve to the water main in the laneway behind 65 Mimosa Road, Bossley Park to control the pressure of the water as it enters homes.

    Thank you for your support and patience during this work.

    Upcoming work

    We still need to install an electrical cabinet and connect the cabling. The cabinet is currently being manufactured offsite. You may have noticed a 3 metre by 1.2 metre concrete foundation in the nature strip outside 2 Quarry Road, this is where the electrical cabinet will be installed.

    When we are ready to install the cabinet, we’ll notify you again. This work will occur during standard daytime hours.

    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.
