Official septic information ↗

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 Washington 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

Washington County issues the septic permit for the whole county, under an on-site sewage facility order the commissioners court adopted and TCEQ approved (Health and Safety Code § 366.031). Section 366.032(b) makes that order prevail wherever it is stricter than 30 TAC Chapter 285. Texas grants county zoning power only in named places, and Washington County is one: Local Government Code Chapter 231, Subchapter J, covers Lake Somerville.

Environmental protections

Nothing in Washington 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.

How Texas permitting works

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 (57.6% of rated soils), followed by bedrock close to the surface (22.9%). NRCS rates 68.7% of rated ground very limited for a standard soil absorption field, 40.3% for subsurface drip and 40.0% for surface application with disinfection. Where a conventional field will not pass, surface application is usually the route that does.
