Coliban Water is undertaking water mains cleaning at the Echuca Water Treatment Plant this week.

Manager Infrastructure Corey Bourne said the cleaning is part of pump station valve replacement works being undertaken at the Treatment Plant this month.

“The mains will be cleaned by a process called flushing, which pumps a high volume of water at high pressure through the pipes to remove the sediment,” Mr Bourne said. 

It’s part of a wider project in which large valves have been replaced within the water mains at the treatment plant to improve its reliability.

“These works are part of a $15 million investment into water and waste water services in Echuca, which will result in greater network efficiency, better water pressure and cater for the growing region,” he said.

The sections of mains that is being flushed will be isolated from the rest of the treatment plant during the works.

The sediment from the flushing is removed, before mains are reconnected to the system. However, there is the small potential for some of the sediment to reach the water supply network as a result of the flushing and cause some minor discolouration.

“The potential is low; however, the water is safe to drink and does not pose a risk to health, remaining compliant with the health-based guideline values in the Australian Drinking Water Guidelines. 

“If you do notice discolouration try running your taps for up to several minutes. If the problem persists, please contact us to report,” he said.

We plan to complete the flushing work on Wednesday 24 June 2020 and the system will be put back online from Thursday 25 June 2020. It may take several days to make its way into the network.

There will be no interruptions to water supply during the works.
