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 are building a new re-chlorination plant within the Campbelltown South Reservoir site off Karrabul Road, Bradbury. The new plant will improve the management of water quality in the region.

    The re-chlorination plant will be built next to the Campbelltown South Reservoir in Bradbury. One building will be constructed, covering an area of approximately 16 metres by 3.5 metres x 3.5 metres high. This new plant will automate the dosing and monitoring of chlorine into the adjacent reservoirs, which gives Sydney Water better control over water quality for its customers.

    The building will be constructed offsite and delivered as a complete unit to be installed onsite. Construction of the new facility will start later in the year. The building will be painted green to help it blend in with its surroundings. A new access road will be built between the existing site access gate and the tanker receiving area.

    Investigation works will start in early April within the Reservoir site and along Karrabul Road, Greengate Road and Merino Crescent.


    Residents will see increased construction traffic around the Bradbury area, particularly along:

    • Karrabul Road

    • Greengate Road

    We are offering property condition surveys to households directly adjacent to the plant works in the coming weeks. An inspector would take a photographic record of in interior and exterior of your home. Once you have received your letter of offer, contact the ProMac community team to arrange your appointment.

    An assessment of the equipment required to construct the re-chlorination plant has been completed and limits set for vibration to ensure that any vibration generated is below levels that could cause structural damage to a home.
