City Of Shelby, Ohio WWTP Eliminates CSOs While Upgrading To A State-Of-The-Art Facility

The City of Shelby, Ohio recently upgraded its activated-sludge wastewater treatment plant to double its capacity to 5 MGD, while expanding its capability to treat and disinfect combined high-volume stormwater and wastewater flows generated by wet-weather conditions. The project, designed to upgrade much of the plant from its original equipment installed in 1953, included improvements to headworks, upgrading primary settling tanks and aeration systems, adding a new final clarifier, replacing chlorination with ultraviolet disinfection, and implementation of a plant-wide SCADA system.
