  Approved Pretreatment Components

Pretreatment Component Approvals

The Ohio Revised Code (ORC) authorizes the Ohio Department of Health and the Sewage Treatment Technical Advisory Committee (TAC) to review and make recommendations to the Director of Health for the approval of Sewage Treatment Systems (STS) components that achieve different levels of sewage treatment. The ODH and TAC review and approval process is intended to ensure that pretreatment component reliability and effluent quality is achieved and maintained. Effluent quality standards from an STS or a pretreatment component are established through various means. These standards are based on water quality requirements in the National Pollutant Discharge Elimination System (NPDES) permit as required by the Clean Water Act for discharging systems, state-established standards for discharge into the soil, local health district requirements for nutrient reduction (nitrogen and phosphorous), and rule provisions related to high-strength waste reduction (small flow or commercial systems).

A complete listing of approved pretreatment systems and components lists components that are approved for one or more of the following: sizing reduction, soil depth credits and NPDES-permitted discharge along with system schematics, system installation and inspection checklists, and operation and maintenance manuals are provided below for each manufacturer authorized for use in Ohio.
