Helena's tap water will soon taste and smell different than usual, as the city is switching to a different supply from Oct. 1 to mid-November.
The city's water will come from the Missouri River instead of the pristine Tenmile Creek west of Helena as officials shut down the Tenmile Water Treatment Facility for about eight weeks for maintenance to the system.
Though the algae in the Missouri River will change the taste and smell of Helena's water, it will remain safe to drink and meet all water quality standards.
Anyone with questions or concerns can call city officials at 457-8555.
"We are fortunate to have two water sources for our city, and we want to be sure our Tenmile pant is in the best possible condition for many years into our future," the city wrote in a press release.
"We appreciate the patience of our residents and businesses as we complete this important maintenance to the Tenmile Plant. This upgrade will allow us to continue to provide quality drinking water to our residents and businesses."
