Western Corridor Recycled Water Project

The Western Corridor Recycled Water Project, part of the South East Queensland Water Grid, is a water supply network designed to diversify the region’s water supplies. It consists of more than 200 kilometres of large-diameter underground pipeline, three advanced water treatment plants, eight storage tanks and nine pumping stations.

The $2.4 billion project is being delivered in three stages and will be complete in December 2008.

Stage 1A

Stage 1A of the Western Corridor Recycled Water Project was completed in August 2007. It involved construction of the Bundamba Advanced Water Treatment Plant, a pipeline to transport secondary treated wastewater from Goodna Wastewater Treatment Plant to Bundamba and a pipeline to supply purified recycled water to Swanbank Power Station. The Stage 1A plant at Bundamba has the capacity to produce up to 20 million litres per day of purified recycled water. It has been supplying water to Swanbank Power Station since 27 August 2007.

Outcome: Supply of purified recycled water to Swanbank Power Station

Stage 1B

The Stage 1B upgrade of the Bundamba Advanced Water Treatment Plant is expected to be completed by mid 2008. Combined, Stages 1A and 1B will have the capacity to produce up to 66 million litres per day of purified recycled water.

Stage 1B of the project also involves construction of more than 100 kilometres of large-diameter underground pipeline–the Eastern Pipeline from Oxley to Bundamba linking wastewater treatment plants to Bundamba Advanced Water Treatment Plant and the Western Pipeline from Bundamba to Caboonbah transporting purified recycled water to power stations and Wivenhoe Dam

Stage 1B of the Western Corridor Recycled Water Project will be complete in June 2008.

Stage 2

Stage 2 of the Western Corridor Recycled Water Project involves constructing the Gibson Island and Luggage Point advanced water treatment plants, a 56-kilometre pipeline connecting them to the system at Bundamba and a pipeline to Wivenhoe Dam.

The advanced water treatment plants and pipelines will be complete in October 2008, with a further upgrade of Gibson Island Advanced Water Treatment Plant to be completed in December 2008.

Once complete, Stage 2 will have the capacity to contribute up to an additional 166 million litres per day of purified recycled water to the South East Queensland Water Grid.

Outcome: The total project will be able to supply up to 232 million litres per day of purified recycled water will be available for use by power stations, industry, agriculture and to supplement drinking supplies in Wivenhoe Dam.
