How does a septic install actually go, step by step?

1. A licensed site evaluator digs test holes, describes the soil profile, and runs a percolation test.
2. A licensed designer or installer builds a system design sized to the number of bedrooms and the soil.
3. The permit application, plans, and fee are submitted to the Fannin County designated representative.
4. The county reviews the paperwork and either approves the design or asks for revisions.
5. After approval, the crew excavates, sets the tank, builds the drain field or spray field, and wires the control panel on aerobic units.
6. The county performs a final inspection before the system is covered and put into service.
7. Maintenance contract paperwork is filed for aerobic systems.

The dig itself is usually two to four days. Permitting adds one to three weeks depending on the county's caseload. Weather is the biggest variable in the spring.

Do I need a conventional or aerobic system in Fannin County?

The soil test decides. Southern and central Fannin County is Blackland Prairie clay, which almost never percolates well enough for a gravity drain field. On those lots TCEQ rules require an aerobic treatment unit with surface disposal. Northern parts of the county, closer to the Red River bottoms, run sandier and sometimes qualify for a conventional gravity system. There is no shortcut around the site evaluation.

What does the TCEQ permit process require?

Every on-site sewage facility in Texas is regulated under 30 TAC Chapter 285. In Fannin County the county designated representative reviews the site evaluation, the design, and the installer's license before issuing a permit. After the install, the same office performs a final inspection before the system can be covered and used. Trying to install without a permit is a compliance problem that follows the property.

What does a Fannin County septic install include?

A clean estimate covers the tank and (for aerobic) the treatment unit, the drain field or spray field, risers and lids to grade, initial pumping if we are replacing an old tank, county permit fees, and the required first year of aerobic maintenance where applicable. Ask specifically about tree work, rock removal, electrical, and any long pipe runs so nothing shows up as a surprise later.

How should I plan for rural well-and-septic lots?

Most acreage builds in Fannin County have a private well on the same lot as the septic system. TCEQ enforces minimum separation distances between wells and any part of a septic system, and any responsible installer respects them even when it means a longer trench run. Talk to your installer before you drill or before you pour the slab so the two systems do not end up fighting for the same corner of the property.
