The city of Zanesville admits raw sewage flows into the Muskingum River. New EPA regulations have asked sewage plants to post signs at sewage overflow pipes. The signs say that during periods of heavy rain fall, the plant becomes over loaded, and sewage combined with storm water dumps into the river. The overflow happens only 4 to 6 times a year. A new sewage plant will be upgraded by 2003. The bigger plant will be able to hold more rain water when we have a big storm.
