Septic services in Old Fort, Ohio

Operators based within 12 miles of Old Fort

Listed by where the business is, not by who it says it serves. Every operator here was on the ODH 2026 sewage treatment system bond lists on the date its record shows, and the address it is placed by comes from that same list, so this is a checkable claim rather than a service-area promise. An Ohio bond covers work in any health district in the state, though each district registers its contractors separately, so operators further out can work here too; these are simply the ones closest to you.

Soil and septic suitability around Old Fort

The USDA has already rated this ground for exactly one use: a septic tank absorption field. Within 4 miles of Old Fort — 32,050 acres across 67 soil map units — it rates 88.3% of the land very limited for that use and 0% somewhat limited, and almost none with no limitation at all.

What the limitation actually is

A rating on its own tells you nothing you can act on. The reasons do, and around Old Fort the leading one is depth to saturated zone on 78.3% of the mapped area, followed by slow water movement on 28.2%. In full:

Limiting featureShare of areaWhat it means on site
Depth to saturated zone78.3%A seasonal water table sits too close to the surface
Slow water movement28.2%Water moves through the soil too slowly for a drain field to keep up
Ponding19%Water stands on the surface
Seepage, bottom layer13.2%The layer beneath the trench is porous enough that effluent could reach groundwater without being filtered
Flooding6.9%The site floods often enough to matter

Shares overlap: most soils here are limited for more than one reason at once, so these do not sum to 88.3%.

The soils themselves

The named soils and land types that make up most of the ground around Old Fort. Kibbie alone accounts for 26.6% of it.

“None in profile” means SSURGO records no bedrock or other restrictive layer within the depth it describes, not that none exists.

Area of interest: a 4-mile radius around the USGS Geographic Names centre point for Old Fort (GNIS 2628948, 41.2419, -83.1514), chosen because five of this state's communities are unincorporated and have no boundary to use, and because the lots that need a septic permit are in the ring around a town rather than inside it. Soil from USDA-NRCS Soil Data Access, SSURGO interpretation “ENG - Septic Tank Absorption Fields”, area-weighted by mapped acreage and by each component's share of its map unit. Survey areas: Sandusky County, Ohio (2025-09-04), Seneca County, Ohio (2025-09-08). Retrieved 2026-09-18.

This is a survey, not an evaluation of your lot. The permit decision rests on the site evaluation ODH carries out for the specific parcel.
