Household Sewage Treatment Systems


Program Services:

The Logan County Health District performs soil evaluation, designs systems, and permits sewage treatment systems with less than 1,000 gallons per day discharge.

Ohio Administrative Code 3701-29 sets forth the minimum standards for household sewage treatment systems in Ohio. This is a new statewide code that became effective on January 1, 2015.


Operation and Maintenance (O&M) Program:


A statewide sewage code that superseded local county sewage regulations went into effect on January 1, 2015. Health districts have been required to develop a sewage Operation and Maintenance (O&M) Program to assess the operating conditions of all private sewage systems within their jurisdictions. The Logan County Health District (LCHD) is in the process of implementing an O&M program for Logan County.

The Ohio Department of Health (ODH) has begun conducting surveys of local health districts to determine the extent of their compliance with the new code’s requirements and expects to survey every county within three years. The state does allow for some variation for each county to accomplish ODH’s stated goal of preventing pollution to the environment by repairing or replacing failed sewage systems. All existing home sewage treatment systems (HSTS) are required to have renewable operation permits. The sewage code gives a maximum limit for the length of an operation permit but health districts can vary renewal times based on the type of sewage system. Sewage systems that are not creating public health nuisances will not be required to be improved.

An OEPA sewage grant program is available to help pay for the costs of  correcting failed sewage systems. The present sewage grant application states that sewer line connections and repairs also now qualify for assistance. The associated poverty guideline charts have also been posted on the LCHD website (loganhealth.org). The Environmental Health Division is continuing with the input
received to date from stakeholders to develop a timeline and process for phasing in O&M management for all prior installed home sewage systems according to the risk factors of system age, complexity due to mechanical components and risks to public health.

A three-tiered division of renewable operation permits is being considered for each sewage system in the county. Annual operation permits will be required for each system that utilizes mechanical components such as pumps and blowers. Operation permits with five (5) year limits will be required for systems that utilize off-lot discharging of wastewater (clear water curtain drains are exempt). This keeps timeframes in line with the five (5) year time limit mandated in the required National Pollution Discharge Elimination System (NPDES) permits already enforced by the OEPA for all wastewater discharged to the waters of the state. All other systems that treat wastewater on lot will have the maximum allowable ten (10) year renewal period.

Following three readings of the revised Logan County Regulation 26, operation permit applications would begin to be mailed after January 1, 2019, to all owners of sewage systems installed prior to January 1, 2015. The operation permits of systems installed after the adoption of the new state sewage code will be honored until their expiration dates. Failure to pay the $50 operation permit
will result in a 25% penalty fee and could eventually be assessed to the property owner’s taxes.

Funds available for failing home sewage treatment systems

The Logan County Health District has received an $84,000 grant from the Ohio EPA's Water Pollution Control Loan Fund to help low to moderate income homeowners repair and replace failing home sewage treatment systems. Depending on household income and the number of residents, homeowners may qualify for 50 to 100 percent of the total costs for home sewage system repair or replacement.

Constructed Wetlands

In an attempt to promote innovative sewage treatment technology, and provide homeowners with more options, some experimental systems such as CONSTRUCTED WETLANDS have been permitted on an experimental basis in Logan County since 1994.

Constructed wetlands are beds of water tolerant plants saturated with sewage and covered with mulch material. The root systems put down by these types of plants maintain oxygen levels in the saturated zone, which allows for much greater "cleaning" of the sewage.

Systems such as constructed wetlands are attractive to homeowners because of their low maintenance requirements and their lack of mechanical devices.
