Permit fees, forms & process

New installs and major repairs need a permit from the local authorized agent — usually the county, sometimes a city — and the rules that bind are the local ones.

This county’s full guide is still in production — the authority contact shown here is the official source in the meantime.

Local rules

What’s different in Walker County.

Four things decide what you can build and what it costs: zoning, environmental protections, power for aerobic systems, and the ground itself. We publish each one only where we have checked it — and say so plainly where the answer is “same as the rest of Texas”.

Zoning & land use

Walker County issues the septic permit for the unincorporated county. It holds that job only because the commissioners court adopted an on-site sewage facility order and TCEQ approved it (Health and Safety Code § 366.031), and § 366.032(b) makes that order prevail wherever it is stricter than 30 TAC Chapter 285. Ask the office for its current order — Texas counties have no general zoning power, so the order, not zoning, is where a local siting rule sits.

Environmental protections

Nothing in Walker County changes this. Texas adds a separate approval path over the Edwards Aquifer recharge, transition and contributing zones, where TCEQ requires an Edwards Aquifer Protection Plan under 30 TAC Chapter 213. Elsewhere the Chapter 285 rules stand on their own.

Checked against TCEQ, 30 TAC Chapter 213 (Edwards Aquifer), Subchapters A and B — Edwards Aquifer and Contributing Zone in Medina, Bexar, Comal, Kinney, Uvalde, Hays, Travis and Williamson Counties (chapter review date 8 March 2024) ↗ · retrieved Aug 7, 2026

Geology & soil

The dominant constraint here is clayey subsoil that water moves through too slowly (44.2% of rated soils), followed by a seasonal high water table (41.6%). NRCS rates 64.0% of rated ground very limited for a standard soil absorption field, 93.8% for subsurface drip and 86.4% for surface application with disinfection.
