Wimmera Mallee Pipeline

The Wimmera Mallee Pipeline Project is the best thing for 100 years

The Wimmera Mallee Pipeline Project is the largest water infrastructure project in Australia, replacing 17,500 kilometres of inefficient earthen channel with 9,159 kilometres of pressurised pipeline and associated structures.

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 will save on average 103 billion litres of water a year and provide a continuous water supply to approximately 9,000 farms and 34 townships across the Wimmera and Mallee.

Thursday 15 April, 2010 saw the Horsham Soundshell come alive with celebrations for the official opening of the Wimmera Mallee Pipeline.

The Wimmera Mallee Pipeline Project was officially opened by then Premier of Victoria, John Brumby and the Minister for Water, Tim Holding, on 15 April 2010.

Federal and State parlimentarians joined GWMWater's then Chairman Barry Clugston to lower the ‘Piping It’ flag and raise the ‘Piped It’ flag with a crowd of more than 1,100 interested community members cheering them on. The flag ceremony symbolised the completion of all pipes laid and officially opened the Wimmera Mallee Pipeline.

Thanks to the pipeline project, made possible by project partners including the Australian and Victorian governments, 36 towns and our 7,000 rural customers are now receiving a high quality and reliable water supply.

Water restriction levels for these customers were eased from Stage 4 to Stage 1 in October 2009 and subsequently moved to Permanent Water Saving Rules in October 2010 as a result of the improved water security that the project has delivered.
