Our access road crosses the eastern end of Gabrugal Yana, and signage and barriers have been installed to direct visitors to a safe crossing. Please check both directions carefully for approaching trucks before crossing.

About Gabrugal Yana
Opening to the public on 22 February, Gabrugal Yana boasts spectacular views to the city and Blue Mountains, as well as a series of unique Aboriginal artwork trees. The new bushwalk is an 11-kilometre return walk from Cecil Park to Middleton Grange that celebrates local Dharug Aboriginal culture by transforming 6 landmark trees into Aboriginal artworks that represent Dharug seasons. Gabrugal Yana means walk of the Gabru or Cabro people, who traditionally lived in the Fairfield and Liverpool area.
First Nations artists Shay Tobin and Djon Mundine OAM worked with Dharug community members to bring the change of seasons to life through artworks that depict well-known Sydney plants and animals such as the blue tongue lizard and the eel, as well as fire. The trees share Dharug names and language, which is accessible through audio that can be heard along the route.
The walk begins at the Wylde Mountain Bike and BMX club in Cecil Park before winding south through Cumberland Plain woodland and old farmland to Middleton Grange.
For more information and updates before your visit, check the Western Sydney Parklands website.
In choosing the route for the brine pipeline, we have minimised the impact on busier areas of the Parklands. However, visitors may come across our construction. Please take care around our construction areas and look out for signage that will direct you to safe crossing points.

We'll work from Monday 3 July until Friday 14 July 2023, weather permitting. Our working hours will be from 8pm to 6am Monday to Friday. We're 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 2 consecutive nights, or more than 3 nights in total in one week.
We will be potholing in the following locations:

• Cross Street at the intersection of Devonshire Road, Kemps Creek

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.

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.
We 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.

As part of our commitment to keep everyone informed, we will produce a general project update newsletter every 6 months, with more frequent, targeted updates posted to the news feed of this webpage.
The first newsletter is the Community update – April 2023.

The contract to construct and operate the Upper South Creek AWRC has been awarded to a consortium of John Holland, Trility, GHD and Jacobs.
Operating at full capacity, the facility will treat around 70 megalitres of wastewater each day and produce high quality treated water for sustainable use in homes and businesses across Western Sydney, and biosolid products for use in agriculture.
Sydney Water Managing Director Roch Cheroux said the plant is an important piece of infrastructure for the region and will leave a positive legacy for the communities of Sydney.
“AWRC will produce high-quality water suitable for a wide range of non-drinking uses for homes, businesses, industrial sites, agriculture and for the watering of public open spaces,” Mr Cheroux said.
The world-class leading facility will be located between Kemps and South Creek and service the Aerotropolis and Western Parkland City.
John Holland will be responsible for the design and construction. GHD and Jacobs will provide engineering and design services, while Trility will provide operations and maintenance advice as the project is delivered.
In a joint venture with John Holland, Trility will be responsible for the operations and maintenance of the facility for up to a 10-year period once completed.
John Holland's General Manager of Water and Optimisation Margaret Riley said she's thrilled to continue a long-term collaboration with Sydney Water alongside partners Trility, GHD and Jacobs.
"It's exciting to launch a project with such industry-leading circular economy ambitions and Sydney Water is to be congratulated on its vision,” Ms Riley said.
Trility’s Managing Director, Francois Gouws, echoes the sentiments of its joint venture partner.
“It's a real privilege to be working in collaboration with Sydney Water and alongside our partners John Holland, GHD and Jacobs on such an exciting project, and one with motivations to drive innovation and a circular economy,” said Mr Gouws.
The Upper South Creek Advanced Water Recycling plant is due to be operational in 2026.

Sydney Water is planning to construct the Upper South Creek Advanced Water Recycling Centre (AWRC) in Kemps Creek and associated pipelines to support predicted population and economic growth in Western Sydney, including designated growth areas known as South West Growth Area and Western Sydney Aerotropolis Growth Area.
We need to survey the land, locate underground services and confirm ground conditions to inform the detailed design of the project. Our investigations will happen at the AWRC site off Clifton Avenue in Kemps Creek and along two pipeline corridors, from Kemps Creek to Wallacia in the west and from Kemps Creek to Lansdowne in the east.
From November 2022 until early 2023, you may see us working in public spaces like footpaths, parks and road reserves. Our work hours are 7 am to 6 pm Monday to Friday and 8 am to 1 pm on Saturdays. We will not work on public holidays.
We will also need to enter a small number of private properties to complete our investigations. Our delivery partner, John Holland Group, will contact directly affected landowners and residents at least 14 days before work needs to happen on private property. We will work with you to confirm access arrangements and suitable times.
To reduce traffic disruption and to ensure the safety of our workers and the community, we may need to work in some busy roads at night for short periods. We will provide advanced notice to nearby residents and will explain how we will reduce impacts from our work.
To know more, please email us at uppersouthcreek@sydneywater.com.au or call our friendly community relations team on 1800 064 127.
Thank you for your understanding during this work.

The Amendment Report reflects seven minor amendments to the project that were made based on feedback from partners and stakeholders. They include minor realignments of the treated water and brine pipelines, and a change to the AWRC site boundary.
DPE will consider any submissions received about the Amendment Report when making a decision about the project.
Please note, Sydney Water’s Amendment Report is not a response to EIS submissions. A separate Submissions Report is currently being prepared by Sydney Water to address submissions received during last year’s EIS exhibition period.
All Upper South Creek AWRC EIS documents are still available at the Upper South Creek Planning Portal page if you wish to review them.

We have also translated the brochure into Arabic, Simplified Chinese and Vietnamese.

Luddenham Village Café (3035 The Northern Road, Luddenham NSW 2745) that was scheduled for Saturday, 3 July due to the Sydney Lockdown.

We postponed the following community pop up information sessions:

• Saturday, 26 June at Settlers Café in Mulgoa
• Tuesday, 29 June in Cabramatta Plaza
• Thursday, 1 July in Cabramatta Plaza

The centre in Kemps Creek, just north of Elizabeth Drive, will provide essential wastewater services for West and South West Sydney for generations to come.
To do this we also need to install two new pipes, one running 17km west and another 24km east.
The 'pop-up' information sessions were critical in allowing us to minimise any potential disruptions in the neighbourhood.
If you missed these sessions and still want to tell us what you think, email us at uppersouthcreek@sydneywater.com.au or call 1800 064 127.

Online session 1: Thursday 18 February 2021.
This session was designed for community interested in the proposed Upper South Creek Advanced Water Recycling Centre. This included community who live and work close to the future centre in Kemps Creek, near Mamre Road and Elizabeth Drive, and the surrounding suburbs of Badgerys Creek, Luddenham and Penrith.

Online session 2: Friday 19 February 2021.
This session was designed for community who live and work in Mulgoa, Wallacia and Warragamba.

Online session 3: Monday 22 February 2021.
This session was designed for community who live and work near the M7 and Western Sydney Parklands, Abbotsbury, Cecil Park, Cecil Hills and nearby suburbs.

Online session 4: Tuesday 23 February 2021.
This session was designed for community who live and work at Bonnyrigg, Bonnyrigg Heights, Busby, Cabramatta, Cabramatta West, Edensor Park, Fairfield, Lansdowne, Mount Prichard, and nearby suburbs.

The centre will be delivered in stages to meet changing customer needs at the right time and support the community as it grows from 25,000 today to 650,000 by 2056.
We expect the first stage to be finished in 2025. When completed in 2036, the plant will treat up to 100 million litres of wastewater daily, producing high quality recycled water that is suitable for a range of uses.
See why our Managing Director, Roch Cheroux is seeking your early feedback about the proposed Advanced Water Recycling Centre project.
In a letter to the community Roch explains why this project will be so important to making every drop of our water resources count to help shape a cooler, greener Western Sydney Parkland City. Read Roch’s letter to the community.
You can also view maps and graphics in our January 2021 newsletter showing how and where the proposed Advanced Water Recycling Centre will operate. Tell us what you think by providing your feedback in this 5min survey.

This formally triggered the start of the Environmental Impact Statement process for one of our largest investments in wastewater management and water resilience in a decade, supporting growth in the South West and Western Sydney Aerotropolis Growth Areas.
The Centre will be located north-east of Elizabeth Drive in Kemps Creek, near the upper Wianamatta-South Creek. When complete the Upper South Creek AWRC will go well beyond existing recycling schemes, moving away from the traditional way of building water infrastructure, and will help redefine the way we value and how we use water more sustainably.
The modular design of the AWRC allows it to be developed in stages to support growth, with wastewater treatment plant to be completed in 2026. The Centre will use industry-leading water and resource recycling technology to harness renewable energy, making this also one of the greenest infrastructure investments in NSW.
The Scoping Report was developed to provide more information on the proposed project, including the development of the Secretary's Environmental Assessment Requirement's (SEARs). Significant stakeholder engagement occurred, keeping a strong focus on creating a world-class customer experience.
The Planning Secretary issued the SEARs in August 2020.

These investigations include general site walkovers, investigation of heritage and ecology, surveying of the area and location of services. it also includes drilling boreholes and excavating test pits to better understand ground conditions and monitoring noise.
Our project team requires access to some properties across Western Sydney, and have been in touch with tenants and owners to conduct these investigations.
We expect we will complete the current phase of investigations by around August and will carry identification and a Certificate of Authority which we will show you at your request.
You may notice us doing these investigations on site between 7 am and 5 pm, Monday to Friday.
You do not need to be at the property during the investigations however if you do have requirements on how we should leave the property, please let us know.

We try to avoid the need to access properties to conduct our investigations, however there may be noise due to our drilling and excavation activities nearby.
