Brazos County septic services.

Brazos County issues the septic permit for the whole county except the city of Wixon Valley. 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.

The dominant constraint here is clayey subsoil that water moves through too slowly (53.8% of rated soils), followed by flooding (26.6%). NRCS rates 69.7% of rated ground very limited for a standard soil absorption field, 75.8% for subsurface drip and 75.8% for surface application with disinfection.
