HELENA — You may have noticed discolored water with an odor, but no need to worry; it is part of the city’s water system maintenance project.

The project involves replacing valve components on the water transmission main that connects the Ten Mile Water Treatment Plant to the city of Helena’s reservoirs. Discolored or different-smelling water in Helena? Here's why.

This will be done in a few phases, and we are in the first one right now. This phase limits the water supply from the Ten-Mile Water Treatment Plant and supplements it with water from the Missouri River Treatment Plant until the construction is complete.

Whenever the Missouri River Plant is turned on, it is common that some residents experience slight discoloration or odor in their water.
