Valve replacement works underway at Echuca WTP

Water mains clearing is taking place at the Echuca Water Treatment Plant as part of pump station valve replacement works.

The mains will be cleaned by flushing – pumping a high volume of water at high pressure through the pipes to remove the sediment.

The cleaning is part of a wider project by Coliban Water, in which large valves have been replaced within the water mains at the treatment plant to improve its reliability.

The sections of mains that are 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, Coliban Water Manager Infrastructure, Corey Bourne, said there was a 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,” Mr Bourne said.

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

These works form part of a $15 million investment into water and wastewater services in Echuca, which aim to create greater network efficiency, better water pressure and cater for the growing region.

Coliban Water planned to complete the flushing work on 24 June 2020 and put the system back online from 25 June 2020.
