Ohio's HSTS Regulatory Framework

In Hamilton County, the Hamilton County General Health District manages HSTS permits for properties outside municipal sewer service areas.
Ohio's HSTS rules establish minimum statewide standards, but county health districts have authority to adopt additional local rules that may be more stringent than the state minimums. Confirm with the Hamilton County General Health District whether any local supplements to ORC 3718 apply to your project.

Licensed Designer and Contractor Requirements
Ohio ORC 3718 requires that HSTS be designed by a licensed soil scientist or professional engineer for certain system types, and installed by a licensed sewage treatment system contractor or plumbing contractor. Hamilton County enforces these licensing requirements.
For conventional systems on straightforward sites, the process may be relatively direct. For systems requiring advanced treatment, pressure distribution, or engineered solutions on challenging sites, licensed design professionals must be involved before the county will issue a permit.
Common HSTS Types in Hamilton County
Hamilton County's varied terrain includes both flat suburban areas and more challenging hillside properties. Approved system types include:
Conventional gravity systems: The baseline for favorable sites with adequate soil absorption capacity.
Pressure distribution systems: For sites where soil conditions require more controlled effluent distribution than gravity provides.
Mound systems: For sites with high water tables or limited depth to limiting conditions, mound systems elevate the drainfield above natural grade.
Aerobic treatment units (ATUs): For sites where conventional systems can't meet treatment requirements, ATUs provide enhanced treatment before drainfield discharge.
The approved system type for your property depends on the site evaluation results and soil conditions observed during the permit application process.

Ohio's HSTS rules include maintenance requirements that go beyond installation permits. Under ORC 3718:
- HSTS must be maintained by licensed contractors
- Certain advanced systems require maintenance contracts
