A $1.45 MILLION upgrade to a water main will help shore up future water supplies to Nemingha, Moonbi and Kootingal.
The major pipe, which connects the city's water with the villages along Armidale Road between East and Crawford streets, is being renewed with a new polyethylene pipeline within the existing pipe.
The council's manager of water operations Daniel Coe said recent issues with the existing pipe had highlighted the need for the upgrade.
"There was a pipe that broke up near the Quest Apartments two years ago and after we did a condition assessment of the pipe, we determined that it needed to be replaced," Mr Coe said.
"The pipeline was originally installed in the 1950s and was actually part of the old Dugowan Dam pipeline that was sent into the old paradise wells.
"It's at the end of its life and we are trying to make sure we have a continual water supply to Kootingal, Nemingha and Moonbi for the next 50 to 80 years."
Construction is expected to be complete in November and Mr Coe said nearby homes and businesses would be minimally impacted.
"The primary reason we have decided to go with a a new polyethylene pipeline was to minimise the impacts on the road construction and the neighbouring properties," he said.
"It's also the cheapest way for this pipeline to be renewed.
"There is a couple of properties we have supplied temporary connections to, so we expect everyone to be in water while the construction occurs."
Construction begins as the city's water catchements continue to rise.
The council's weekly water update shows Dugowan Dam still sits at 100 per cent, while Chaffey Dam has risen to 22.63 per cent and Split Rock Dam has risen to 4.62 per cent.
The rises come after a prolonged rain event across the region last week.
"It's always good news when it rains over Chaffey Dam," Mr Coe said.
"Chaffey is currently just sitting under 23 per cent and I think they are expecting 20mm of rain later this week, which hopefully means more in flows into Chaffey over the weekend."
