The BioCEPT facility achieved full operation on December 27, 2021 ahead of the mandated completion date. This facility has the ability to treat an additional 60 million gallons of wastewater per day and allows the plant to provide full biological secondary treatment of wastewater for up to 280 million gallons per day. 

BioCEPT is a high rate, wet weather treatment process where biological microorganisms are used to stabilize untreated wet weather wastewater. After biological treatment, chemicals are added to further treat and purify the water. The excess flows treated by the BioCEPT process are combined with the conventionally treated wastewater prior to disinfection and release to the Cuyahoga River.
