Commercial Septic System Installation & Water Well Drilling in Houston, TX

When a site sits beyond city water and sewer, the septic system and the well become part of the critical path. We plan, permit and build both alongside the rest of the site work.

A growing share of commercial work around Houston — c-stores, truck stops, travel centers, warehouses and industrial yards on the edge of the metro — is built on land with no municipal water or sewer to tie into. On those sites the on-site sewage facility (OSSF) and the water well are not side items. They are the utilities, and the certificate of occupancy waits on both.

We handle them the same way we handle the rest of our underground scope: planned against the building, sequenced against the site work, and installed with our own excavation equipment. The septic system and well are coordinated with grading, drainage, paving and the building’s plumbing, so the drain field does not end up under a future parking lot and the well is not drilled where the fuel tanks need to go.

Every regulated step — site evaluation, system design, installation and well drilling — is carried out by professionals holding the Texas licenses that step requires.

Why most Houston-area sites need an aerobic system

A conventional septic system relies on the soil to treat effluent as it drains away. Much of Greater Houston sits on dense Gulf Coast clay with a shallow water table, and that soil simply does not absorb water fast enough for a conventional drain field to work reliably.

Aerobic treatment units solve that by treating the wastewater before it ever reaches the ground, typically discharging through surface spray or drip distribution. They cost more and they require ongoing maintenance, but on clay soil they are often the only design that can be permitted — and the only one that keeps working.

The site evaluation decides it. Soil analysis and site conditions determine which systems are allowed, and the design follows from there rather than from a preference.

How OSSF permitting works in Texas

On-site sewage facilities in Texas are regulated by the TCEQ under 30 TAC Chapter 285. Permits are issued by a local authorized agent — in unincorporated Harris County, the Office of the County Engineer — or by a TCEQ regional office where no local agent exists. Constructing, altering or repairing a system requires a permit and an approved design.

The sequence is consistent: a licensed site evaluator assesses the soil and site, the system is designed (aerobic and other secondary-treatment systems must be designed by a Professional Engineer or Registered Sanitarian), the permit is issued, and the installation is inspected before it is covered. Aerobic systems also require an initial two-year maintenance contract with a licensed maintenance provider.

Commercial systems add their own considerations: higher and more variable daily flows, grease from food service, and the need to fit everything around fuel systems, truck circulation and detention. Getting the OSSF design started early keeps it off the critical path.

Water wells and the subsidence districts

Water wells in Texas are drilled and equipped by drillers and pump installers licensed by the Texas Department of Licensing and Regulation (TDLR), and a well report is filed with the state when the well is completed.

Around Houston there is an additional layer. The Harris-Galveston and Fort Bend subsidence districts regulate groundwater pumping because of the land subsidence it causes, and commercial wells within their boundaries must be permitted or registered before drilling. Depending on the regulatory area and the volume pumped, ongoing reporting and fees can apply.

Well location matters as much as the permit. Required separation distances to septic tanks, drain fields and other potential contamination sources shape the whole site layout, which is why the well and the septic system are planned together rather than one after the other.

Planned with the site, not after it

The most common septic and well problems on commercial sites are layout problems: a drain field that collides with future paving, a well drilled inside a required setback, a tank that ends up under a truck route. Each one is expensive to fix once the site is built.

Because we self-perform site work, grading, underground utilities and paving, the septic system and well are placed and sequenced as part of one site plan. Excavation, tank setting and service connections are handled by the same crews building the rest of the underground scope.

How It Runs

Our process

  1. Step 01

    Site evaluation

    Soil analysis, site conditions and setbacks assessed to determine which septic systems are allowed and where the well can go.

  2. Step 02

    Design

    The OSSF is designed by a Texas PE or Registered Sanitarian to the building’s actual flows, and the well is specified for its demand.

  3. Step 03

    Permits

    OSSF permit through the county or TCEQ authorized agent, and well permitting with the subsidence district where it applies.

  4. Step 04

    Drill & install

    Well drilled and equipped; tanks set, treatment units and distribution installed, coordinated with the rest of the site work.

  5. Step 05

    Inspect & connect

    Installation inspected before backfill, then connected to the building sewer, water service and electrical.

  6. Step 06

    Start-up & handover

    Systems commissioned, the aerobic maintenance contract set up, and well and OSSF records handed to the owner.

FAQ

Common questions

Do I need an aerobic septic system in the Houston area?

Often, yes. Much of the region has dense clay soil and a shallow water table that do not drain well enough for a conventional drain field. The site evaluation and soil analysis determine which systems can be permitted on your property.

Who issues septic permits in Harris County?

In unincorporated Harris County, OSSF permits are issued by the Harris County Office of the County Engineer. Other counties and cities have their own TCEQ authorized agents, and the TCEQ regional office issues permits where no local agent exists.

Who designs a commercial septic system in Texas?

Aerobic and other secondary-treatment systems must be designed by a Texas Professional Engineer or Registered Sanitarian, based on a site evaluation by a TCEQ-licensed site evaluator. Commercial systems are sized to the building’s expected daily wastewater flow.

Is a maintenance contract required for an aerobic system?

Yes. Texas requires an initial two-year maintenance contract with a licensed maintenance provider for aerobic treatment units and other secondary-treatment systems. After that the owner must keep the system maintained, either under contract or after completing the required training.

Do I need a permit to drill a water well near Houston?

Commercial wells within the Harris-Galveston or Fort Bend subsidence districts must be permitted or registered with the district before drilling. Wells are drilled by TDLR-licensed drillers, and a well report is filed with the state on completion.

Can the septic system and well be installed as part of a larger project?

Yes — that is where we add the most value. Planning both alongside grading, drainage, paving and the building plumbing avoids setback conflicts and keeps the certificate of occupancy on schedule. We also take on septic and well work as a standalone scope.
