Western Corridor Recycled Water Project (Qld, Australia)

Share on:

The AUD$2.5 billion Western Corridor Recycled Water Project is Australia’s largest water recycling scheme and the third-largest advanced water treatment project in the world.

It uses secondary wastewater from Brisbane and Ipswich, to produce 232Ml of purified recycled water a day. The project is the Queensland State Government’s response to unprecedented demand on its water supply due to population growth, climate change and the worst drought in recorded history.

As an active member of both the collaborative Western Pipeline Alliance and Eastern Pipeline Alliance teams, GHD informed the early development, strategic framework, leadership, and governance of the project land acquisition, design and construction. GHD also formed part of the owner’s project management group, providing engineering and environmental management services across the pipeline and advance water treatment plant alliances.

As a climate-independent water source, the scheme reduced pressure on region dams and waterways, securing water supply to South East Queensland for current and future domestic, commercial, industrial and rural users.

GHD also provided an environment and approvals team to Department of Infrastructure and Planning to undertake Environmental and Social Impact Assessments (ESIAs) in early project stages. These documented the full range of environmental impacts and required mitigation measures, and formed the basis of community engagement activities around the project. Over 100 development approvals were obtained for the project with no delays to construction or commissioning.



As the world’s population grows and our standards of living improve so does our need to manage the water in our environment. We need to maximise its application for human well-being and minimise impact on the environment. GHD engineers, scientists and planners can provide sustainable, cost-effective and innovative water solutions.  We assist water utilities and others who provide water services to optimise infrastructure and adapt to environmental changes in ways that balance the needs of our communities. And we enable clients to meet compliance, improve profitability and maintain their commitment to sustainability.

GHD continually expands the boundaries by engaging in research, enhancing existing systems and strategies, evaluating new procedures and transferring technology from other industries into the water industry. We work with our clients through all project stages planning, investigation, design, delivery, operation and renewal.

Water Treatment & Desalination


All untreated water sources have unique water quality characteristics. So we’ve assembled a team with extensive practical experience in water treatment covering chemistry, biology, hydraulics, process selection, control, residuals handling and plant layout.

Our track record includes plant capacities of 0.1 MLD to over 2500 MLD. We’ve dedicated our efforts to more than 300 treatment plants over the past 60 years. Our services include design of water treatment process solutions as diverse as Dissolved Air Floatation Filtration (DAFF), Ozone/Biological Filtration and Desalination (using Reverse Osmosis or Electrodialysis Reversal).
