Proposed Wyaralong Water Treatment Plant
To support a safe, reliable and resilient water supply for South East Queensland into the future, Seqwater is currently planning for a new water treatment plant to connect Wyaralong Dam to the SEQ Water Grid.
South East Queensland’s (SEQ) population is set to grow, putting greater demand on existing water supply assets.
Under current levels of demand, the region has enough spare water supply to manage through a severe drought, however it’s important we remain vigilant and prepare now for future changes to keep pace with population growth.
Seqwater is always looking at ways to optimise the use of the SEQ Water Grid and existing assets.
To prepare us for the future, we have started planning for a new water treatment plant downstream from the existing Wyaralong Dam and a connection to the SEQ Water Grid as an additional drinking water source.
Wyaralong Dam is the newest dam in South East Queensland, completed in 2011 in response to the Millennium Drought. Its connection to the SEQ Water Grid would assist in meeting future water demand for the growing communities in Beaudesert and southern Logan areas.
About the project
Seqwater is currently undertaking a business case to explore a new Water Treatment Plant downstream from Wyaralong Dam and connection to the SEQ Water Grid.
The proposed plant would support the growing Beaudesert and surrounding communities.
The business case is expected to be completed in 2024.
Seqwater is committed to keeping the local community informed as planning progresses.
The project is in business case stage, which is expected to be completed in 2024.
Why are you proposing to use water from Wyaralong Dam for drinking water supply?
Wyaralong Dam and the Cedar Grove Weir were built during the Millennium Drought to provide an additional drinking water source for South East Queensland. The drought broke around the same time construction was completed on these projects, and construction of the new water treatment plant and bulk water pipeline were deferred. The completion of these projects is being explored through a detailed business case, in line with Seqwater’s Water Security Program 2023 – a 30-year strategy which sets out bulk water supply for the region to cater for population growth and other factors.Where will the new water treatment plant be built?
Subject to business case approval, a proposed new water treatment plant would be built adjacent to the Cedar Grove Weir, with water supplied from Wyaralong Dam and the Logan River.

Subject to business case approval, the new water treatment plant would supply Beaudesert as well as the growing communities of Flagstone and Yarrabilba. This will reduce the existing demand on the SEQ Water Grid from the Logan area.
