Household Sewage Treatment Systems


Program Services:

The Logan County Health District (LCHD) issues the permits for sewage treatment systems with less than 1,000 gallons per day of discharge.

Ohio Administrative Code 3701-29 sets forth the minimum standards for all household sewage treatment systems (HSTSs) in Ohio. This statewide code superseded all local county sewage regulations and became effective on January 1, 2015.


Operation and Maintenance (O&M) Program:


Health districts are required to conduct sewage Operation and Maintenance (O&M) Programs to evaluate the operating conditions of all private sewage systems within their jurisdictions. The LCHD is in the process of implementing its O&M program for Logan County, starting with a 2-year assessment period. All existing HSTSs are required to have renewable operation permits. Existing sewage systems will be classified according to the risk factors of system age, complexity due to mechanical components and risks to public health to determine whether a 1-year, 5-year, or 10-year operation permit will be issued.

The Ohio Department of Health (ODH) has begun conducting surveys of local health districts to determine the extent of their compliance with the sewage code’s requirements and expects to survey every county within three years. ODH’s goal for the program is to prevent pollution of the environment through the repair or replacement of failed sewage systems. Sewage systems that are not creating public health nuisances will not be required to be improved except for the addition of missing inspection risers on septic tanks, distribution boxes and sewage-carrying tiles that leave propertys.

For households that financially qualify, OEPA sewage grant money is available to help pay for the cost of correcting failed sewage systems. The sewage grant application also allows for existing sewage systems to become connected to pubic sanitary sewer. The associated poverty guideline charts have been posted on the LCHD website at loganhealth.org.

A three-tiered division of each sewage system in the county has been created to assign renewable operation permits. 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 renewal period of ten (10) years.

According to the revised Logan County Regulation 26, operation permit applications began to be mailed after January 1, 2019, to all owners of private 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 all unpaid fees can be assessed to the property owner’s taxes.

The Environmental Health Division is continuing, with input received from stakeholders, to develop a process and a timeline for phasing in the inspection and management part of the O&M program. After all of the home sewage systems in the county have been assessed, an inspection will be required during the term of each operation permit. Inspections can be made by the septic pumper, a service provider or a sewage system installer, even the homeowner after proper training. If a system does not get inspected, the LCHD will conduct the inspection for $50 but not provide any service or repair.

Funds available for failing home sewage treatment systems

The Logan County Health District has received a $150,000 grant from the Ohio EPA's Water Pollution Control Loan Fund to help low to moderate income homeowners repair and replace failed home sewage treatment systems. Depending on household income and the number of occupants, homeowners may qualify for 50, 85, or 100 percent of the cost for a 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.
