Permits & Texas regulations

Do I need a permit to install a septic system in Texas?

In nearly every case, yes. A permit and an approved plan are required before you construct, install, alter, extend, or repair an on-site sewage facility. In counties that act as TCEQ authorized agents, the county issues the permit and inspects the work, often through a designated representative who reviews the plans.

What is 30 TAC Chapter 285?

It’s the section of the Texas Administrative Code that governs on-site sewage facilities — the design standards, setbacks, permitting process, and licensing requirements every legal septic system in Texas has to meet. When we say a system is built to code, this is the code.

Can my county have stricter rules than the state?

Yes. Permitting authorities are allowed to adopt requirements more stringent than the state minimums, and some do. That’s why we check the rules for your specific property rather than assuming the state baseline applies everywhere.

What is the 10-acre exemption?

It allows a single-family home on a tract of 10 acres or more to skip purchasing a permit and submitting planning materials — but only if no effluent crosses the property line and every part of the system stays at least 100 feet from all property lines. It’s one of the most misunderstood rules in Texas.

Does the 10-acre exemption mean the rules don’t apply?

No, and this is where people get into trouble. Permit-exempt is not regulation-exempt. A site evaluation is still required, and the system still has to meet every design, construction, and setback standard in Chapter 285. You skip the paperwork, not the engineering.

Can I install a septic system myself?

Only under narrow conditions: it must be your own single-family residence and you must physically do the labor. Anyone paid for any part of the work has to hold a state license. Some permitting authorities don’t allow homeowner installation at all, so check before you dig.

Does an emergency repair need a permit?

If the tank can be repaired without removing it, no permit is needed up front — but the work has to be reported to the permitting authority within 72 hours. Replacing a tank or repairing a drain field does require a permit and must meet current standards.

What happens if someone files a complaint about my system?

The permitting authority investigates. If the system is found deficient, you generally get 30 days to make substantial progress on the fix before the agent can file a criminal complaint with the local justice of the peace. Addressing it early is far cheaper.

Costs & estimates

What does a septic system cost in West Texas?

It depends on your soil and the system it supports. Conventional systems are the most affordable. Aerobic systems, often required where soil drains poorly, commonly run $10,000 to $20,000 statewide, plus the site evaluation and design. We give free on-site estimates with real numbers.

What does a site evaluation cost?

Most Texas homeowners pay roughly $250 to $600, depending on lot size and how many test holes are required. It’s a required step before permitting, and it’s what determines the type and size of system your ground can support.

Should I get more than one estimate?

Yes, and the state itself recommends getting several and checking references. We’d rather you compare than wonder. One caution: be wary of a bid far below the others — it usually means something’s being left out that you’ll pay for later.

Should I pay a large amount up front?

Be careful with that. Texas requires a construction trust account for contract amounts over $5,000, which exists to protect you. A contractor asking for most of the money before work starts is a warning sign worth taking seriously.

Are your estimates really free?

Yes. We come out, look at the property, and give you a written estimate with no charge and no obligation. If we think you don’t need the work, we’ll tell you that too.

Choosing & sizing a system

What is a site evaluation and why does it come first?

A licensed Site Evaluator or Professional Engineer surveys the lot and analyzes the soil in the proposed disposal area. Everything else depends on the result — it determines whether your ground can support a conventional system or requires an alternative, and what size that system needs to be.

What’s the difference between a conventional and an aerobic system?

A conventional system uses your soil to filter effluent through a drain field. An aerobic system actively treats the wastewater before disposal. Aerobic systems cost more and require ongoing maintenance, but they’re often the only option where soil drains poorly or lots are small.

Why would my property need an aerobic system?

Because most Texas soils can’t properly absorb pollutants on their own. When the soil analysis rules out a conventional drain field, an alternative treatment method is required. The soil makes that decision, not your budget or preference.

How is my system sized?

By the load it has to handle and what your soil can absorb. Household size and water usage drive the design flow; the site evaluation determines what the ground can take. Undersizing to save money is how systems fail early.

Do aerobic systems require a maintenance contract?

Yes. Systems using secondary treatment or drip irrigation need inspection roughly every four months by a licensed maintenance provider, unless homeowner maintenance is permitted where you are. Ask what that contract costs after the first two years — it’s part of the true cost of ownership.

Maintenance & keeping a system healthy

How often should my septic tank be pumped?

Every three to five years for most households, by a TCEQ-registered sludge hauler. Skipping it allows solids to build up and carry over into the drain field, and clogged soil is damage you don’t easily undo.

Do septic additives or enzymes work?

No. TCEQ specifically advises against chemical additives and so-called enzymes. Normal household use supplies all the bacteria a tank needs. Additives won’t dissolve what actually accumulates, and they’re no substitute for pumping on schedule.

Can I build or drive over my septic system?

Never. That includes driveways, patios, sidewalks, sheds, barns, and parking. The weight compacts the soil and can crush lines and crack tanks. We find structures sitting on drain fields more often than you’d expect.

What should never go into a septic system?

A septic system treats domestic sewage only. Industrial waste, solvents, chemicals, and oilfield fluids kill the bacteria the system depends on and will destroy it. If anything beyond household wastewater goes down a drain on your property, the system has to be designed for it.

What are the warning signs of a failing system?

Slow drains, sewage odor, soggy or unusually green patches over the drain field, gurgling pipes, or an alarm. If effluent reaches the surface, stop using water inside and call. A failing drain field gets more expensive every week it goes unaddressed.

How long does a septic system last?

With proper maintenance, a well-built system lasts a long time — but as a general guideline, once a system passes 15 years it’s worth having evaluated. Whether repair or replacement makes sense depends on what’s actually failing.

Buying or selling property

I’m buying a property with a septic system. What should I check?

Ask the county for permit records or as-built drawings showing where the tank and lines are buried. On older rural properties those records are often thin or missing entirely. Your lender may require its own evaluation before closing, and getting the system assessed before you sign beats inheriting a failing one.

I’m buying raw land. How do I know what it will take?

Get a site evaluation before you buy. It tells you whether the ground supports a conventional system or will require a much costlier alternative — and that difference can change what the land is actually worth to you.

Can an unpermitted system cause problems at resale?

It can. A buyer’s lender or the county may require the system to be evaluated, documented, or brought up to current standards before closing, and if it was built without a permit there may be no record showing the work was done properly.

Our other services

Do you do more than septic work?

Yes. We handle six lines of work: septic installation and repair, demolition, excavation and site work, land clearing and earth grading, concrete, and utilities. Many jobs touch several of those at once.

Why hire one contractor for multiple parts of a job?

One crew, one schedule, one point of accountability. When the dirt work, the septic system, the utilities, and the concrete are all handled by the same outfit, there’s nobody to point fingers at when something doesn’t line up — and coordination stops being your problem.

Do you call 811 before you dig?

Every job. Texas law requires notifying 811 so existing utility lines get located and marked. It’s free and it protects you as much as us. Anyone willing to skip it is putting liability on your property.

Do you work on farms, ranches, and commercial properties?

Yes. We do residential, agricultural, and commercial work across the region — from a single repair at a house in town to site work on acreage well out in the county.

What areas do you serve?

Lubbock and roughly sixty miles in every direction, across Lubbock, Hockley, Terry, Lamb, and Hale counties. If you’re not sure whether you’re in range, call and ask.
