Electoral district of Hayward

Lonsdale is an industrial suburb south of Adelaide, South Australia, within the City of Onkaparinga. Lonsdale was farmed from shortly after European settlement until the 1950s, when the South Australian Housing Trust acquired much of the land for industrial use. Mobil's Port Stanvac Refinery and Chrysler's engine foundry were followed by many other manufacturing and service industries. Subsequent suburban development of surrounding areas has driven demand for a wide range of service-oriented businesses in the area. Port Stanvac Refinery and the Mitsubishi (formerly Chrysler) engine plant closed in 2004, with both sites remaining unused as of 2007. The South Australian Government announced plans to build a seawater desalination plant at the site in 2007, to provide fresh water for Adelaide. The Adelaide Desalination Plant opened in 2013.

In September 2007, South Australian Premier Mike Rann announced that the State Government would fund and build a desalination plant to ensure Adelaide's water supply against drought. The plant was financed and built by SA Water, a state-owned corporation. The plant was initially planned to have a capacity of 50 gigalitres (GL) of water per year but was later doubled in capacity to 100 GL/year with the assistance of funding from the Australian Government. The expanded capacity represents around 50% of Adelaide's domestic water supply.
