Septic services in Sullivan, Ohio

Operators based within 12 miles of Sullivan

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 Sullivan

The USDA has already rated this ground for exactly one use: a septic tank absorption field. Within 4 miles of Sullivan — 32,048 acres across 93 soil map units — it rates 98.2% 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 Sullivan the leading one is depth to saturated zone on 97.2% of the mapped area, followed by slow water movement on 92.8%. In full:

Limiting featureShare of areaWhat it means on site
Depth to saturated zone97.2%A seasonal water table sits too close to the surface
Slow water movement92.8%Water moves through the soil too slowly for a drain field to keep up
Ponding12.6%Water stands on the surface
Flooding4.3%The site floods often enough to matter
Seepage, bottom layer2.7%The layer beneath the trench is porous enough that effluent could reach groundwater without being filtered

Shares overlap: most soils here are limited for more than one reason at once, so these do not sum to 98.2%.

The soils themselves

The named soils and land types that make up most of the ground around Sullivan. Bennington alone accounts for 43.9% 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 Sullivan (GNIS 2812806, 41.0211, -82.2147), 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: Ashland County, Ohio (2025-08-27), Lorain County, Ohio (2025-09-02), Medina County, Ohio (2025-09-02). 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.
