This involved acting as adviser during the design and construction phase and taking over responsibility from client Seqwater for the long term operations and maintenance as construction was completed.
This is the largest advanced recycled water scheme to be constructed in Australia and the third largest advanced water treatment project in the world.
The scheme is part of the Queensland Government's South East Queensland Regional Water Strategy and Water Grid to supply south east Queensland with a reliable, long term water supply not dependent on rainfall. It has the capacity to provide up to 232 million litres a day of purified recycled water.
Construction on the Western Corridor Recycled Water Project began in 2007. The project involved building a network of more than 200 km of pipeline to take treated water from six existing wastewater treatment plants (located throughout Brisbane and Ipswich) to three new advanced water treatment plants:
- Bundamba - 66 million litres per day
- Gibson Island - 100 million litres per day
- Luggage Point - 66 million litres per day
There are seven stages of water treatment to ensure safe drinking water is supplied through the Western Corridor Recycled Water Project.
Three of these stages are within the Advanced Water Treatment Plants operated by Veolia Water.
These plants create purified water to a quality that can be reused by industry (such as the nearby Tarong and Swanbank Power Stations). It can also be returned to Wivenhoe Dam, the main drinking reservoir for south east Queensland if the combined levels of Wivenhoe, Somerset and North Pine Dams drop to below 40 per cent.
