Septic Tanks

The regulation of septic and other sewage tanks in Ohio is governed by the requirements in OAC 3701-29-07 and Amended Substitute House Bill (Am. Sub. HB) 363, Section 120.02 (C)(3). Local health districts that issue STS permits must ensure all sewage component tanks utilized within their jurisdiction comply with these provisions. The link below is to the aforementioned regulations.

Precast Concrete Voluntary Septic Tank Compliance Program

The Ohio Precast Concrete Association (OPCA) and ODH jointly developed a procedure to provide local health departments the access to testing information on precast concrete sewage component tanks. Through the voluntary compliance program, manufacturers of precast concrete sewage component tanks have the option to submit testing data. The data are meant to demonstrate compliance with the requirement in law that all tanks are structurally sound and watertight. This compliance program is strictly voluntary. Below are the links to the guidelines set forth in the program and participating manufacturers.

Prefabricated Septic Tanks

OAC Rule 3701-29-20 allows for household sewage disposal system components or household sewage disposal systems differing in design or principal of operation from those set forth in rules 3701-29-01 to 3701-29-21 of the Ohio Administrative Code to qualify for approval as a special device or system, if comprehensive test and investigations show any such component or system produces results equivalent to those obtained by sewage disposal components or systems complying with such regulations.

Based on the review of the submitted information, the Director of Health approved the following trash traps/pump tanks or septic tanks as a special anaerobic sewage treatment device for use in Ohio.

Pre-2007 Septic Tank Reviews
Prior to rule changes on Jan. 1, 2007, ODH compiled the following list of septic tanks that either met the criteria of Ohio Administrative Code Rule 3701-29-07 or were approved as a special device differing in design from the dimensions specified in the rule. This review process was voluntary for tank manufacturers. The listed tanks were not reviewed for water tightness or structural soundness. Local health districts that issue sewage treatment system permits must ensure the provisions in Am. Sub. H.B. 363, Section 120.02 (C)(3) requiring water tightness and structural soundness are met.
