Water Treatment Plant


Coldwater's water treatment plant was designed to remove iron and manganese but not soften municipally supplied water. The water utility is protecting the water supply with a wellhead protection program. It is one of the first of its kind in the state of Michigan. The wellhead protection program identifies which lands impact the water producing aquifer and establishes guidelines for informing the public and governmental agencies on protecting the watershed.
