What is the project’s scope?

    The scope of work includes the construction and operation of: 

    • a new Advanced Water Recycling Centre in Kemps Creek 

    • a pipeline to release high quality treated water to the Nepean River at Wallacia 

    • a pipeline to take the plant’s saline by-product (brine) to the existing wastewater network at Landsdowne 

    • associated ancillary infrastructure. 

    Who is delivering the project?

    John Holland, Sydney Water’s delivery partner, is responsible for design and construction, while GHD and Jacobs are providing engineering and design services. Trility is providing operations and maintenance advice during delivery and will be responsible for operating the AWRC during its first five years. 

    What are the project’s benefits?

    This project will deliver sustainable wastewater treatment and high-quality recycled water to create a cooler, greener Western Parkland City, with a wide range of benefits for the entire community including: 

    • providing efficient and cost-effective wastewater services 

    • producing high-quality, recycled water for a range of potential non-drinking reuses 

    • potential to recycle organic waste to generate electricity 

    • helping to protect 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 

    • generating renewable energy within the AWRC 

    • building a centre that can respond to changes in demand as our community grows. 

     

    The AWRC is Sydney Water’s largest investment in infrastructure for Western Sydney and provides a foundation for a circular economy hub in the Parkland City which would investigate the opportunity to develop a future bioenergy hub at the AWRC for waste collection, reuse, resource recovery and renewable energy generation. 

     


    What areas will be serviced by the AWRC?

    The centre will provide wastewater services to the South West Growth Area and Western Sydney Aerotropolis Growth Area as indicated by the servicing catchment as indicated by the red line on our project map.  

    How much water will be processed per day?

    When operating at maximum capacity, the facility will treat around 70 megalitres (approximately 28 Olympic size swimming pools) of wastewater each day and produce high-quality treated water for sustainable, non-drinking water reuse in homes and businesses across western Sydney and biosolid products for use in agriculture.  

    How will wastewater reach the AWRC?

    Wastewater will be transported to the Upper South Creek Advanced Water Recycling Centre (AWRC) for treatment via a network of pipelines, some of which have already been constructed, as well as new pipelines, mains and pumping stations that are under construction or planned to be constructed.

     The AWRC will centralise the treatment of all wastewater generated in the Upper South Creek Servicing Area, which includes homes and businesses in Austral, Leppington North, parts of Leppington, parts of Catherine Fields North, Rossmore, and Kemps Creek.  Some parts of these areas are currently connected to Sydney Water’s Liverpool and West Camden Water Recycling Plants, which are reaching capacity. This, combined with the rapid growth and development of the region support the need to provide additional wastewater capacity by constructing the AWRC.

     When the AWRC is completed in 2026, it will be able to treat a daily wastewater flow of up to 35 megalitres a day. The associated pipelines, however, will cater for up to 70 megalitres a day so that the AWRC can be expanded in the future to treat an increased flow to align with growth in demand in the servicing area.

    How can I connect to wastewater services?

    Sydney Water builds major infrastructure and trunk pipelines as part of its network. Trunk pipes are large water and wastewater pipelines that customers can’t connect directly into. After trunk mains are built, developers or property owners need to build the next stage of pipelines, called reticulation or lead-in pipelines, to connect services to individual properties. For more information visit the Connections page on our website. Developers can find more information on the Plumbing, building and developing page on our website. 





     

    How can I get access to recycled water?

    Sydney Water supports the use of recycled water and/or harvested stormwater to meet non-drinking demands. We are in the early phase of planning and feasibility for recycled water service from the AWRC. The recycling scheme and timing is subject to the outcome of the planning study.  

    You can read more about our indicative servicing plans via Sydney Water‘s Growth Servicing Plan (2022-2027). Further information about potential demand for non-drinking water helps us in our investigations, please email us to register your interest.  

    How can I find out more about water treatment, wastewater and recycled water?

    he AWRC will meet world’s best practice for wastewater treatment through using the highest level of treatment. It uses reverse osmosis (the same technology used by Sydney Water’s desalination plant) in addition to a membrane bioreactor to treat water to a high quality.
