Watershed Protection and Unfiltered Supply. The production of high-quality water starts at the source: the Cedar River Watershed. The watershed encompasses 90,500 acres of forest land. The land is undeveloped, with no housing, no industry, no agriculture, so the water is not exposed to contaminants from these activities.
How long does water stay in contact with ozone?
The water stays in contact with the ozone for about 10 to 20 minutes to complete the disinfection and oxidation processes, disinfecting pathogens and improving the taste and odor of the water. Rather than build a new ozone contact chamber, the facility uses two 78-inch-diameter pipelines for ozone contact.
