The plans were presented to Parliament's Public Works Committee last week.

The Government says the pipelines will deliver water from Tailem Bend and Strathalbyn to households and properties in the Raukkan, Narrung, Meningie and Langhorne Creek districts and along the Poltalloch Peninsula.

Minister for Water Security Karlene Maywald says about 120 kilometres of pipeline will be built which will improve water security and guarantee consistent water quality for communities currently sourcing water from the Lower Lakes.

"Tenders will be called shortly for companies to build the pipelines with construction scheduled to start by the end of September," she said.

"First water will be delivered to communities by early 2009.

"The Langhorne Creek and Currency Creek irrigation communities are also working on the proposal to build a pipeline network to supply irrigation water to the region by 2009-10."
