The work over a week and a half will be undertaken by council contractor Suez using the innovative technology known as ice pigging.
The cleaning process involves semi-solid ice slurry being pumped into a section of the water mains, which is then pushed along the pipe using the natural pressure in the network.
As the ice flows through the pipe, it passes over every surface and collects sediment.
Ice pigging is a much quicker and more effective way to clean pipes than traditional flushing techniques. It uses 50 percent less water, and means interruption to water supply for residents and businesses is relatively short.
Water efficient cleaning techniques are critical during times of water restrictions and council uses this technology to reduce the water required while effectively cleaning water mains and improving water quality.
The Greenmeadows area, Town Beach area (north of Burrawan St and east of Lord St) and the Lake Rd area (in the vicinity of the Private Hospital) will be cleaned.
Council director Jeffery Sharp said there may be an impact on businesses and residents during the water pipe cleaning, however work will be scheduled to minimise any disruption, including conducting the cleaning outside of peak usage times, or at night where required.
"We understand that some businesses rely on a constant water supply, and we will be contacting businesses within the cleaning area to provide an indication of when cleaning will take place and discuss options to minimise the impact," Mr Sharp said.
"In addition, council will be writing to residents and businesses in the areas to be cleaned at least 24 hours before the interruption occurs."
Homes and businesses impacted by the cleaning can expect minor interruptions to their water supply lasting approximately two hours. During the cleaning, it is advisable not to operate any device that uses water, such as dishwashers and washing machines. If discoloured or cloudy water is experienced after the interruption period, an outside tap should be run until the water runs clear.
"While the impact on homes will be minimal, council encourages businesses to contact us directly should they have any specific questions or concerns," added Mr Sharp.
