The Wimmera Mallee Pipeline Project was one of the largest water infrastructure projects in Australia, replacing 17,500 kilometres of inefficient open channels with 9,159 kilometres of rural pipeline.

Construction of this great engineering feat commenced in November 2006 with the last pipe being laid in April 2010, well ahead of the 10 year timeframe originally proposed and within the $688 million project budget. The pipeline was officially opened by then Premier of Victoria, John Brumby and then Minister for Water, Tim Holding, on 15 April 2010.



The pipeline saves on average 103 billion litres of water a year and provides a continuous water supply to approximately 7,000 rural customers and 36 towns across the Wimmera and Mallee. Thanks to the pipeline project, these customers now receive a high quality and reliable water supply.

More about the benefits of connecting to a rural pipeline.



GWMWater has honoured 13 individuals who have made outstanding contributions towards securing the Wimmera Mallee Pipeline for our region. Completing the project would not have been possible without many years of sustained effort and advocacy by this group of committed pipeline ambassadors.
