Water main upgrades flow across regional SA

Regional communities across South Australia will benefit from around 40,000 metres of water main upgrades in 2022-23, as SA Water continues to deliver its $155 million water main management program.

Among the regional centres receiving pipe renewals are Whyalla, Tanunda and Yankalilla, along with smaller towns such as Hamley Bridge and Curramulka, securing a safe and reliable supply of water for local residents and businesses.

SA Water’s General Manager of Sustainable Infrastructure Amanda Lewry said this year’s program builds on the 60,000 metres of water main that were replaced across country areas of the state during 2021-22.

“Our ongoing program of works aims to maintain the structural integrity of the water network, including helping to reduce the potential for water main leaks and breaks,” Amanda said.

“Water main breaks can happen as a result of several reasons, including the age of the pipe, condition of the soil, temperature of the ground and pressure changes.

"While it isn't possible to completely prevent a water main leak or break, our management program is a proactive way of reducing the frequency of these incidents and mitigating any impact to customers.

“A comprehensive prioritisation system helps to identify which water mains need replacing, based on factors including likelihood of future breaks and the potential impact of a break on customers and commuters.

“Our 2022-23 regional program also includes the installation of network valves, to help minimise the number of properties affected when water is temporarily disrupted during any pipe repairs.”

Water mains have long service lives of up to around 100 years, helping to maintain a reliable supply of drinking water for regional and metropolitan communities well into the future.

“Investing in a reliable water network supports the needs of current residents as well as future population growth, benefitting the local economy and protecting public health," Amanda said.

As each water main replacement is planned and carried out, SA Water will ensure local residents are given advance notice of any temporary water supply interruptions, which can be necessary when their connection is moved over to a new water main.
