Quick answer

Before a septic system is installed in Texas, the site is evaluated, a system is designed to fit the soil and the home, and a permit is obtained from the county's authorized permitting agent. Brown Aerobic handles design and permitting, then installs the system. Call 832-789-5357 to start with a site visit.

Before a septic system can be installed in Texas, the site has to be evaluated, the system designed for it, and a permit approved. Brown Aerobic Septic Specialists handles all of it: we coordinate the site evaluation, design, county permit and installation so you deal with one company from the first visit to the final inspection. We work with homeowners and builders across Harris, Montgomery, Waller, Fort Bend, Austin, Grimes and Brazoria counties.

What septic design and permitting involves

Septic permits in Texas follow the state's on-site sewage facility rules (TCEQ, 30 TAC Chapter 285). In most counties a local authorized agent issues the permit and inspects the work.

A licensed site evaluator examines the soil and site. Depending on the system and county, a licensed professional engineer or registered sanitarian may also be involved in preparing the planning materials. We coordinate that work so you do not have to.

Our process

  • Site visit and soil and site evaluation.
  • System selection and design: aerobic with spray or drip dispersal, or another approved option for your lot.
  • Permit application and fees, submitted to the permitting authority for your county.
  • Installation after approval, followed by inspection.
  • Start-up and maintenance contract for aerobic systems.

What we need from you

  • The property address or legal description, and a survey or plat if you have one.
  • House plans or the bedroom count, and any planned additions or outbuildings.
  • Locations of wells, easements, pools, trees and anything else on the lot that affects setbacks.

Common obstacles we plan around

Small or irregular lots, floodplain areas, a high water table, heavy clay, and setbacks from wells, creeks and property lines. Good design solves most of these; a poorly designed system is the usual reason for permit problems and repairs later.
