Water Quality & Treatment

Water Quality

The health of our customers and community is of vital importance to us. Cleveland Water works hard to ensure that our customers receive the highest quality water at all times.

Drinking water in the United States is regulated by the U.S. Environmental Protection Agency (EPA). To ensure your tap water is safe to drink, the EPA prescribes regulations limiting the amount of certain contaminants in your water. The Partnership for Safe Drinking Water (Partnership) is a voluntary effort between the EPA and 200 drinking water utilities across the United States. As a member of the Partnership, Cleveland Water holds itself to higher water quality standards than those required by the EPA. We perform self-assessments of our water treatment operations, identify performance limiting factors, and take corrective actions to improve water quality.  We have completed the required self-assessment and optimization programs at each of our four water treatment plants. This large effort ensures that our customers receive great-tasting water with a higher degree of protection.

Water Quality & Treatment

Our Source Water

Our source for drinking water is Lake Erie, which is one of the five Great Lakes. Over 90% of the water entering Lake Erie comes from the upstream lakes - Superior, Michigan and Huron - as well as the rivers and streams that flow into these lakes. The remaining water comes from rain and snow in the Lake Erie drainage basin, including the streams and rivers that flow into Lake Erie. As water travels over the land or through the ground, it can pick up substances that are harmful to humans.

We use surface water drawn from four intakes in Lake Erie. Our intake systems are located a considerable distance offshore to protect our water from possible contamination. Your water goes through a thorough treatment process that includes removing small debris, filtering, and disinfecting the water to meet drinking water quality standards.

Cleveland Water regularly collects and tests about 300 water samples a day to ensure that the water our customers receive exceeds federal and state drinking standards.
