Sydney Water is building the Upper South Creek Advanced Water Recycling Centre (AWRC) in Kemps Creek and associated pipelines to support population and economic growth in Western Sydney.

Construction Information

Our delivery partner, John Holland, is building the AWRC, a treated water pipeline from Kemps Creek to the Nepean River at Wallacia and a brine water pipeline from Kemps Creek to our existing wastewater network at Lansdowne. The pipelines are built underground, mostly in road reserves and public spaces. Some sections of pipeline will need to be installed across private properties.

Construction is underway in parts of Badgerys Creek, Bonnyrigg, Bonnyrigg Heights, Cabramatta, Cabramatta West, Canley Heights, Canley Vale, Cecil Hills, Cecil Park, Elizabeth Hills, Fairfield, Green Valley, Kemps Creek, Lansdowne, Lansvale, Luddenham, Mount Pritchard, Mulgoa and Wallacia.

Our standard working hours are 7 am to 6 pm Monday to Friday and 8 am to 1 pm Saturday. We will notify affected people in advance if we need to work outside these hours.

John Holland is working hard to minimise disturbance however some people may experience temporary traffic changes and construction impacts, mostly from machinery that will be used to dig trenches and lay pipes. Construction of the pipelines will occur until late 2025.

When completed in 2026, the AWRC will deliver sustainable wastewater services and high-quality recycled water to support a cooler, greener Western Parkland City, with a wide range of benefits for the entire community.

Community Benefits

Key benefits for the local community include:

  • efficient and cost-effective wastewater services
  • producing high-quality, recycled water for a range of potential reuses
  • potential to recycle organic waste to generate energy
  • protecting local waterways and aquatic ecosystems via environmental flows
  • producing biosolids for an alternative to chemical fertilisers in agriculture
  • enhancing biodiversity by greening Western Sydney with recycled water
  • supporting the vision for the Western Parkland City, to create quality places for the community, keep water resources in the catchment to support greening and reduce heat island effects
  • generating renewable energy within the AWRC
  • a centre that can respond to changes in demand as our community grows.

The AWRC is Sydney Water’s largest infrastructure investment in Western Sydney and when competed will provide a foundation for a circular economy hub in the Parkland City.

Planning Process

In 2021, Sydney Water prepared an Environmental Impact Statement (EIS) to describe the project and assess its environmental and community impacts.

The EIS was submitted to the Department of Planning and Environment (DPE) and put on public exhibition from 21 October to Wednesday 17 November 2021, giving the community an opportunity to review and make submissions on the findings presented in the document. DPE provided planning approval on 28 November 2022.

    As detailed design and construction planning progressed, Sydney Water and its delivery partner, John Holland, identified several opportunities to reduce the project’s environmental and community impact. This included avoiding some impacts to threatened biodiversity and heritage as well as reducing impact to the community by simplifying some construction activities.

    Eight alignment changes were proposed, located in the local government areas of Wollondilly, Penrith, Fairfield and Canterbury-Bankstown. These include:

    • relocation of the flow control valve station (Bents Basin Road, Wallacia)
    • realignment of the treated water pipeline at Golfview Drive, Wallacia and Elizabeth Drive, Badgerys Creek
    • realignment of the brine pipeline at Bartley Street, Canley Heights
    • realignment of access to Lansdowne Reserve
    • temporary implementation of three underbore return lines at Nepean River, Jerrys Creek and Badgerys Creek.

    Sydney Water prepared a Modification Report to assess the potential impacts of the proposed changes. This was publicly exhibited by the Department of Planning and Environment (DPE) for 14 days from 18 July to 31 July 2023. A total of 12 submissions were received. We responded to each submission via a Submissions Report.

    The modification application was approved by the DPE on 10 October 2023.

    Our delivery partner, John Holland, will be completing investigation work by potholing to confirm the location of underground utilities along the route of the brine pipeline in Kemps Creek, Cecil Hills, Green Valley, Bonnyrigg, Bonnyrigg Heights, Cabramatta West and Canley Vale.

    We will work from Monday 3 July until Friday 14 July 2023, weather permitting. Our working hours will be from 8 pm to 6 am Monday to Friday. We are completing this work at night to maintain safety for road users and workers and to keep people moving during peak travelling times.

    We will use concrete saw cutters, excavators and vacuum trucks to form a pothole and confirm the location and depth of underground utilities. If required, jack hammers will also be used. We will also use lighting towers to light our work area. We will then fill and compact the pothole and restore the road or footpath surface.

    This work will be noisy however we will coordinate our work so that residents do not experience noise for more than two consecutive nights, or more than three nights in total in one week.

    We will be potholing in the following locations:

    • Cross Street at the intersection of Devonshire Road, Kemps Creek
    • Western Road between Elizabeth Drive and Overett Avenue, Kemps Creek
    • Feodore Drive near Spencer Road, Cecil Hills
    • North Liverpool Road between the Liverpool-Parramatta Transitway and Whitford Road and at Currawong Street, Green Valley
    • North Liverpool Road at the intersection of Montgomery Road, Bonnyrigg
    • Montgomery Road near Kincumber Road and Brown Road, Bonnyrigg
    • Montgomery Road near Holdin Street, Bonnyrigg

  • Draft Urban Design and Landscape Plan (UDLP)

    Share Draft Urban Design and Landscape Plan (UDLP) on Facebook Share Draft Urban Design and Landscape Plan (UDLP) on Twitter Share Draft Urban Design and Landscape Plan (UDLP) on Linkedin Email Draft Urban Design and Landscape Plan (UDLP) link

    We have prepared a draft UDLP to set the strategy and design for the urban landscape and design at the AWRC. The UDLP focuses on the development of Stage 1 of the project (operational site) however considers opportunities for engagement around the future masterplan for green space (Stage 2) with relevant stakeholders.

    Landscape design is important for the AWRC as it will help us achieve place-based outcomes through designing and caring for Country (in partnership with our Aboriginal stakeholders) and to support biodiversity through providing a restored landscape and a sustainable wastewater service now and into the future.

    The plan will be submitted to the Department of Planning and Environment in late July 2023. You can review the plan here. For more information or to provide feedback, email us at uppersouthcreek@sydneywater.com.au or call our community relations team on 1800 064 127.

    The environmental flows pipeline was initially planned to support waterway health by releasing highly treated water into the Nepean and Hawkesbury Rivers. However, this will now be achieved by releasing the same water via the Treated Water pipeline, removing the need to build the environmental flows pipeline.

    Descoping this pipeline from the project will avoid the environmental and community impacts associated with its construction and operation. This includes potential impacts on some threatened biodiversity and heritage and avoids impacts from construction-related noise and traffic around Wallacia and Warragamba.

    Sydney Water prepared a Modification Report to assess the potential impacts of the proposed change. This was publicly exhibited by the Department of Planning and Environment (DPE) from 5 April to 18 April 2023. A total of 10 submissions were received, none of which objected to the proposed modification. We responded to each submission via a Submissions Report.

    The modification application was approved by the DPE on 26 May 2023.
