Leave room in the build schedule for the Erath inspection
Erath County's published application checklist calls for at least five working days' notice to the inspector before the construction inspection. It also says excavations must stay open until inspection is complete. Confirm current arrangements with the office before scheduling backfill or the next builder's work.
That makes the inspection part of the site-work sequence, rather than something to arrange after the trenches are covered.

Check usable septic area before buying or splitting an Erath lot
For lots covered by Erath's subdivision rules, the published area calculation excludes drainage easements, wet-weather creek beds and banks, bodies of water, and road-widening easements. The rules refer septic lot requirements back to the OSSF order or designated permitting agency.
Bring the actual plat when discussing a new homesite or acreage split. Ask the office to check usable area with the proposed home, access, and drainfield, rather than relying on the acreage in a listing.

Know who supplies the evaluation and planning materials
The Erath checklist asks for a licensed site evaluation and soil/site report. It distinguishes standard-system planning from non-standard or proprietary planning that needs a PE or sanitarian. Ask who is preparing each part of the package before treating an installation quote as the whole approval process.

Planning an Erath County acreage build
Stephenville, Morgan Mill, Bluff Dale, Huckabay, Dublin, Lingleville, and surrounding communities have entries in the local field guide. The actual property may be a different drive from the town reference point, so send its location and county rather than assuming the mailing town confirms coverage.
If you are still buying land, ask for the survey, existing septic permits and layout, and information about sewer availability before settling on a house location. If you already own the property, tell Tanner what is changing: a new home, a replacement system, or a change to the planned home use. Those are different starting points for an installation conversation.
Gather the site and home information before installation
Bring the proposed bedroom count, house plan, water source, survey or plat, and locations of existing improvements. Mark where the driveway, pad, well if present, and drainage features sit. Leave the potential septic area available for evaluation instead of choosing the field after the other work is finished.
A site evaluation and the required planning materials need to establish that the land can support the proposed system. Tanner is the conventional septic installer; ask who will prepare the evaluation and planning materials, and when the required approvals and inspection need to happen. An installation quote should make those responsibilities clear.

Line up clearing, pad work, and the septic layout
A rural new build can involve several decisions before the septic system goes in. Tell Tanner whether clearing or grading has started, whether the builder has fixed the home elevation, and whether a septic plan already exists. Work outside a planned field still needs to account for access and where water will go.
Tanner can discuss land clearing, excavation, and site prep along with a conventional installation, or take a standalone dirt-work inquiry. Each scope needs to be clear. Photos of the entrance, proposed pad, and work area help him understand what you are trying to accomplish before a site visit and quote.
FAQ
Do you install conventional septic near Stephenville and Morgan Mill?
Tanner considers eligible properties in those parts of Erath County within roughly 50 miles of Santo. Confirm the property location, county, road access, and scope before planning the work.
Which Erath County paperwork should I gather first?
Start with the survey or plat, property location, proposed home plan and bedroom count, water source, and existing septic records if there are any. Use the official planning resources and ask the responsible permitting office which application, evaluation, and planning materials it requires.
Does acreage guarantee room for a conventional drainfield?
No. Acreage alone does not establish suitability or an approved layout. The evaluation, home use, improvements, water features, and applicable requirements need to be considered for the actual property.
