Warren County Combined Health District, Lebanon Ohio

Environmental Health — Sewage Treatment Systems

Many residents of Warren County utilize individual home sewage treatment systems, since sanitary sewers are not accessible to a large part of the County. Our Environmental Health Staff issue installation permits and conduct inspections of all new, replacement, and altered (repaired) sewage treatment systems (STS) within Warren County in order to assure the installation was completed correctly and to code.

The Warren County Combined Health District (WCCHD) works to prevent disease transmission and to protect the quality of surface and ground water by enforcing sewage treatment system rules and regulations. This is done by conducting inspections and providing education to homeowners and registered sewage installers.

When purchasing a lot to build a new residence, a soil evaluation must be completed by a soil evaluator who meets the requirements set forth in Ohio Administrative Code Chapter 3701-29. Once a soil evaluation is completed a system design must be made that also meets requirements set forth in the Ohio Administrative Code. System design based on soil characteristics protects ground and surface water resources, helps to prevent residents and neighbors from exposure to sewage-borne disease, and maximizes the life of the system. After the soil evaluation and system design an application for a site review must be filled out with this office to verify that the system design is appropriate for the lot.

After the soil conditions, lot size, and house location are evaluated potential systems available for installation include: septic tank with leaching tile field; aeration tank with leaching tile field; septic tank or aeration tank with mound system; or a drip distribution system. A Sewage System Permit to Install and operating permit must be obtained from the WCCHD prior to installation. The registered sewage system installer must call to schedule an inspection prior to backfilling the system.

Following installation and final approval of the sewage treatment system, the system is placed in the Operation/Maintenance Program whereby the sewage system is inspected by the WCCHD staff within one year of installation and every three years thereafter.

The WCCHD staff also provides free consultative services to homeowners who are experiencing problems with their existing sewage treatment system upon receipt of a consultation request.

Draft statewide sewage treatment regulations have recently been proposed and are currently going thru the adoption process with a potential implementation date in early 2014. To obtain a copy of the rules and stay informed during the rule adoption process, an individual can go to the Ohio Department of Health website.
