Sewage Operation & Maintenace
(O&M) Program

Program Overview

In January 2015, the Ohio Department of Health adopted new rules regarding private sewage treatment systems (STSs) in Ohio (Ohio Revised Code: 3718 and Ohio Administrative Code: Chapter 3701-29). These rules require each health department and/or district across the state to implement a local Operation and Maintenance (O&M) program to monitor and ensure the proper function of STSs in their jurisdictions. ​


For questions about HCPH's O&M Program, please call 567-244-3239.

Program Effective Date: March 25th, 2019

The Sewage O&M program will require every STS in the county to have an O&M permit. Permits will ensure systems are monitored and maintained on a regular basis so that failing systems may be identified and addressed. A STS that is not properly functioning can release bacteria, viruses, and chemicals into the groundwater and local waterways. This poses a risk of spreading various diseases in the community, as well as, polluting drinking water and the environment.

A general overview of the O&M Program can be found below.

Public Health Nuisance

If a STS is found to be causing a public health nuisance according to Ohio Revised Code 3718, the property will be entered into the program.

Risk Priority

HCPH will use risk factors such as the age of the system, potential waterway contamination, and other factors to determine the order in which all other STSs in the county will be entered in the program.

Existing Installation Permits

Once a property is entered into the O&M program, HCPH will determine if an existing installation permit is on file for the property. If no permit is on file, property owners may choose to have a STS component verification completed. 


To find out if you have an existing installation permit on file for your property call 567-244-3239.


If a property's STS does not have an existing installation permit, property owners choose not to verify components, or components cannot be verified, a STS will need to be installed on the property.


STSs that have an existing installation permit or whose components are able to be verified will be evaluated to determine if the system is causing a public health nuisance according to Ohio Revised Code 3718. 

If no nuisance is found, an O&M permit will be issued. If a nuisance is found to be occurring, the property owner will need to work with HCPH to repair and/or replace their STS to eliminate the public health nuisance.
