Wastewater Treatment Department
The City of Norwalk's Wastewater Treatment Plant, located at 201 Plank Road, is designed to treat an average flow of 3.5 million gallons of wastewater a day, with a peak flow of 8.2 million gallons a day. The plant operates around the clock. 2022 average daily flow is 2.26 mgd.
Wastewater from throughout the city travels through a series of pipes and pumping stations into two 24-inch interceptor sewers that lead to the plant. The wastewater is subjected to a complicated treatment process before being released as clean water into the west branch of Rattlesnake Creek.
The City of Norwalk is aware of the taste and odor complaints regarding the water. Personnel from multiple departments have been responding to, sampling, and testing many locations. All tests completed have met or exceeded Ohio EPA standards. Actions have been taken in an attempt to alleviate the issues. Additionally, you may see hydrants being flushed to bring fresh water to the area. The water is completely safe and poses NO THREAT TO PUBLIC HEALTH. We appreciate your patience while we determine the source.
If you have additional concerns, please contact the General Services Department at 419-663-6715.
