Texas septic permits and rules: who regulates what

In Texas you need a permit and an approved plan to build, alter, repair, extend or operate a septic system, and you usually get it from a local authorized agent, not TCEQ. Small emergency repairs can start first if the permitting authority gets written notice within 72 hours. [1] [2] [3]

Not legal advice. Local permitting authorities can set stricter rules than the state minimum, so check with yours before you start work.

When you need a permit

The basic rule

Texas rules say a person must hold a permit and an approved plan to construct, alter, repair, extend or operate an on-site sewage facility (OSSF, the state's term for a septic system), unless one of the rule's exceptions applies. [1] [2]

Replacing a tank or a drain field

TCEQ says a permit is required, whatever the system's age, when a tank has to be replaced or a drain field repaired or replaced. Any work on the disposal area means the system has to meet current standards. [4]

Emergency repairs

Some repairs can start without a permit: replacing tank lids or inlet and outlet devices, repairing risers and riser caps, repairing or replacing disinfection devices, repairing damaged drip irrigation tubing, and repairing solid lines. The repair must be made to abate an immediate, serious and dangerous health hazard and must not change the system's approved design. Whoever makes it must notify the permitting authority in writing within 72 hours of starting, describing the methods and materials, and the authority may inspect. TCEQ adds that if a tank can be repaired without removing it, the work counts as an emergency repair. [3] [2] [4]

Routine pumping

TCEQ lists pumping by a registered sludge hauler as routine care and does not list it among the jobs that need a permit. Only a company registered with TCEQ as a sludge transporter may haul septic tank waste. [4] [5]

When a property sells

A septic permit transfers to the new owner automatically when the property is sold. [1]

Exceptions: older systems and large tracts

Both exceptions are narrow. Your local permitting authority decides whether one applies.

Older ("grandfathered") systems

TCEQ says a system may not need a permit if it was installed before September 1, 1989, or before the local program was authorized, whichever is earlier, and it is not creating a nuisance, not in need of repair, and has not been altered or had a significant increase in use. Once it needs repair, those conditions no longer hold. [2] [1]

The 10-acre rule

A system may be exempt from permitting only if all of these are true: a TCEQ-licensed Site Evaluator or professional engineer evaluated the site; it serves one single-family home on a tract of 10 acres or more, and that home is the only dwelling on the tract; it is not causing a nuisance or polluting groundwater; every part is at least 100 feet from the property line; the effluent (treated wastewater) stays on the property; and it meets the state's planning, construction and installation standards. [2] [1]

Local rules can remove these exceptions

TCEQ notes that local permitting programs can be more stringent than state minimums. Fort Bend County, for example, says existing systems there are not grandfathered and that the 10-acre exemption does not apply in the county. [2] [6]

Who issues permits

Usually a local authorized agent

TCEQ says it is not often the permitting authority. In most places a local government that TCEQ has authorized to run the septic program (an authorized agent) issues permits: a county, city, river authority, health district or water district. Where no local program is authorized, the TCEQ regional office is the permitting authority. TCEQ's OARS lookup, an online search by county, lists the contact for your area. [2] [7] [1] [8]

The state law and rules

Texas Health and Safety Code Chapter 366 is the state law behind the septic permit program, and Title 30 Texas Administrative Code Chapter 285 holds the rules. [2]

How the permit process runs

  1. Get a site evaluation from a TCEQ-licensed Site Evaluator or a licensed professional engineer. It includes a survey of the lot and a soil analysis where the disposal area will go. [2]
  2. Pick a system the site supports. TCEQ suggests weighing the up-front cost, ongoing operation and maintenance (including what a maintenance contract will cost after the first two years), repairs, replacement of mechanical parts and expected life. [4]
  3. Submit the application, planning materials, site evaluation and fee to your permitting authority. [1] [2]
  4. Wait for the decision (see below). If approved, you get an authorization to construct, which is good for one year. [1]
  5. The installer asks for a construction inspection at least five working days before the system is ready, and the permitting authority inspects it before it can be used. [1]
How long review takes

The permitting authority must approve or deny the application within 30 days of receiving it, and must explain a denial in writing. TCEQ says you can appeal to the authority's supervising body, such as the commissioners court, city council, river authority board or public health district board. [1] [2]

Authorization to construct

The permitting authority's written permission to build a septic system. In Texas it is valid for one calendar year; if the installer doesn't request the construction inspection within that year, it expires and a new application and fee are needed. [7] [1]

Systems that need continuous maintenance

For systems that state rules say need ongoing maintenance, such as aerobic systems, the owner must record an affidavit in the county deed records before the authorization to construct is issued. It states that such a system is on the property and that the permit passes to a new owner with the property. [1]

Installing your own system

TCEQ says you can, if your permitting authority allows it, the system serves a single-family home you own on property you own, no part of the property will be developed for sale or lease, and you meet all permitting, construction and maintenance requirements. Anyone who helps, such as with backhoe work or trenching, must be a licensed installer of the right class, except a licensed electrician doing the electrical work or someone delivering and setting a tank. [2]

Hiring an installer

TCEQ's advice is to get at least three estimates and, if one is far from the other two, ask that installer what it added or left out. It also warns against paying large sums in advance: Texas Property Code 162.006 requires a construction trust account for amounts over $5,000 when a contractor has a written contract with an owner. [4]

Who does what: TCEQ licenses and registrations

Each job has its own credential. You can look up any of them in TCEQ's license search; sludge transporters have a separate registration lookup.

TCEQ credentials for septic work and what each covers
CredentialWhat it coversSource
Sludge transporter (TCEQ registration)Hauling septic tank waste. Registration is required before operating; it is not an installer or maintenance license.[5], [9]
Site Evaluator (TCEQ license) or Texas professional engineerPre-construction site evaluations to decide whether a site suits a particular system.[10]
Installer I (license)Standard systems: septic tanks, absorptive drain fields, unlined evapotranspiration drain fields, leaching chambers, gravel-less pipe and pumped effluent drain fields.[10]
Installer II (license)All types of septic systems, including aerobic systems.[10]
Apprentice (registration)Installation work only under the constant, direct supervision of a licensed installer.[10]
Maintenance Provider (license)Service and maintenance of systems that use aerobic treatment.[10]
Maintenance Technician (registration)Maintenance work only under the direct supervision of a Maintenance Provider.[10]
Designated Representative (license)Works for an authorized agent: inspections, complaint investigations, system evaluations and, where it is part of the job, site evaluations.[10]
How to check a credential

Use TCEQ's licensing and registration search for installers, site evaluators and maintenance providers. For a sludge transporter, search TCEQ's Central Registry with the program set to SLUDGE. [11] [12]
