Apart from Binningup and Kemerton, cost estimates for the other sites had only been developed to a very conceptual stage.
The cost to develop a desalination plant at Binningup, including connecting infrastructure is estimated at $955 million (outturn dollars). The cost to develop a desalination plant at Kemerton would incur a cost penalty in the order of $150 million (outturn dollars). Potential desalination sites at Port Kennedy and East Rockingham are now no longer under consideration because of the environmental concerns with the discharge to the Warnbro Sound. Potential desalination sites to the north of Perth have also not been given detailed consideration because of the distance to existing power assets and water supply infrastructure.
(2) The cost breakdown for the Binningup site is:
· $640 million for the desalination plant.
· $233 million for the infrastructure to expand the existing Integrated Water Supply Scheme to accommodate the addition of 45 gigalitres a year.
· $82 million to connect the plant to the Integrated Water Supply Scheme.
As mentioned above, the cost to develop a plant at Kemerton would be approximately $150 million more.
(3) The formal assessment by the Environmental Protection Authority of the Binningup site has not yet commenced.
(4) The discharge pipe will extend approximately 800 metres offshore to a point where the water depth is a minimum of 10 metres.
(5) The Global Positioning System co-ordinates of the end of the discharge pipe will not be known until the final design of the outfall is completed.
