Your Wharton County septic installer
Across Wharton County's rural land, most homes run on their own on-site septic system instead of city sewer. We design, permit, and install new septic systems for new construction, manufactured, and mobile homes throughout the county — including El Campo, East Bernard, Boling, Louise, Hungerford, Glen Flora — handling the soil and percolation testing and the county OSSF permitting from start to finish.
We install new septic systems across Wharton County, from Wharton and El Campo out to East Bernard, Boling, Louise, Hungerford, Glen Flora, and the farm communities like Danevang, Egypt, Lane City, and Pierce. This is working farmland southwest of Houston — rice, cattle, and row crops — where most homesites sit on acreage beyond the reach of any sewer line. The towns are different: Wharton and El Campo have city sewer, and East Bernard, Boling, Hungerford and Louise have district sewer in their cores. Whether it's a new house on family land, a manufactured home, or a rebuild, we size the system, pull the county permit, and install it to pass both county authorizations.
What we install in Wharton County
Site Evaluation & Perc Testing
We evaluate your soil and run the percolation test that determines how well your ground absorbs water — the foundation of a system that works.
System Design & Sizing
We size the tank and drainfield to your home's bedroom count and your soil's absorption rate, then engineer a layout that fits your lot.
Permitting & County Approval
We prepare and submit your on-site sewage facility (OSF) permit application and coordinate approvals with your county health department.
Excavation & Site Prep
We prepare the site and excavate for the tank and drainfield with the right grade and setbacks — protecting your wells, structures, and property lines.
Tank Installation
We set the septic tank, connect the inlet and outlet plumbing at the correct grade, and install the effluent filter and risers for easy future access.
Drainfield Installation
We install the drainfield (leach field) that disperses treated effluent safely into the soil, sized to your percolation results and available area.

We handle Wharton County permitting
On-site sewage facilities (OSSF) are permitted at the county level. We prepare the application, submit the soil and design documentation, and see it through approval and final inspection — so your Wharton County system is fully permitted and passes the county inspection.
In unincorporated Wharton County and the City of East Bernard, septic permits run through the Wharton County Permit & Inspection Department at 315 East Milam in Wharton; the county's program doesn't cover the cities of Wharton and El Campo. The county's own OSSF application collects the property's legal description, the water supply details (public system or private well), and the facility details — bedrooms, square footage, and design flow — that TCEQ 30 TAC Chapter 285 sizing runs on, and it names the licensed site evaluator, system designer, and installer on the form. Authorization comes in two stages the county tracks on that same form: an Authorization to Construct before work starts, then an Authorization to Operate after the county's inspection. The county permits everything from standard trench systems to low-pressure dosing, drip, and surface application, and its septic order requires every installer to be licensed by TCEQ and registered with the department before doing any septic work. We prepare the packet, file it, and see it through both authorizations.

Soil & site conditions in Wharton County
Wharton County is Gulf Coast rice prairie, and the soil survey reads accordingly: deep clays and clay loams — the Lake Charles, Bernard, and Edna series dominate around El Campo and East Bernard, with Colorado and San Bernard bottomland soils such as Norwood loam and Brazoria and Pledger clays near Wharton and Boling — that are very slowly permeable, with high shrink-swell and seasonal wetness. Ground like that holds water at the surface after rain instead of letting it soak away, which is exactly what fails the TCEQ criteria for a conventional gravity drainfield. Most new systems here are aerobic units with surface application or drip dispersal, sized under Chapter 285. The on-site soil evaluation confirms the class and the design for your specific tract.
What a new septic system costs in Wharton County
Our installed prices are flat by system type and cover the system and its installation. The soil evaluation (perc test), the engineered design, and the county permit are not included — we can handle them for you and quote them separately. The soil evaluation also decides which of the three systems your lot needs.
| System type | Installed price |
|---|---|
| Conventional gravity | $8,000 |
| Aerobic (ATU) + spray | $11,950 |
| Aerobic (ATU) + drip | $13,950 |
Wharton County sets its OSSF permit fee at application rather than publishing one. It isn't included in the prices above.

Wharton County septic questions
Do I need a permit for a septic system in Wharton County?
Yes. A new on-site sewage facility (OSSF) requires a county permit plus a soil/site evaluation before installation. We handle the full permitting process for you, start to finish.
How much does a septic system cost in Wharton County?
It depends on your soil type, system type, and drainfield size. Use our instant estimator for a ballpark, then we confirm the exact price after a free on-site evaluation.
Do you install septic systems for manufactured and mobile homes?
Yes — manufactured and mobile homes on rural Wharton County land are what we install most. We size and permit the right system for your home and lot.
Who issues septic permits in Wharton County, and what does the permit cost?
The Wharton County Permit & Inspection Department at 315 East Milam Street, Suite 102, in Wharton issues OSSF permits for unincorporated land and the City of East Bernard — (979) 532-8587. Its program doesn't cover the cities of Wharton and El Campo. The county doesn't publish its permit fee online, so the current amount is confirmed directly with the office when we file. We handle the application and the fee logistics as part of your install.
What does the Wharton County septic application involve?
The county's OSSF application collects the property's legal description, your water supply details (public system or private well), and the facility details — bedrooms, square footage, and design flow — that TCEQ Chapter 285 sizing is built on. It also names the licensed site evaluator, designer, and installer. The county then issues an Authorization to Construct before work starts and an Authorization to Operate after inspection. We prepare and file all of it.
Why do most Wharton County homes need an aerobic system?
The county's rice-prairie soils — Lake Charles, Bernard, and Edna clays — are very slowly permeable with high shrink-swell, and water stands on them after rain. That fails the TCEQ criteria for a conventional gravity drainfield on most sites, so an aerobic unit with surface application or drip dispersal is the standard design here. Your on-site soil evaluation confirms it for your tract.
Can you install a septic system for a manufactured or mobile home in Wharton County?
Yes. Manufactured homes on acreage around El Campo, Boling, Louise, and Hungerford need their own permitted on-site system, and the county process is the same as for a site-built house — application, site evaluation, design, Authorization to Construct, licensed installation, and the inspection that unlocks the Authorization to Operate.
What's the difference between the two authorizations the county issues?
Wharton County splits the permit into an Authorization to Construct — issued once the application, evaluation, and design are approved, before any dirt moves — and an Authorization to Operate, issued after the county inspects the finished system. The system isn't legal to use until the second one. We schedule the inspection and close out both so your home can go live.
Does the county care who builds the system?
Yes. The application names the licensed installer up front, and the county's septic order requires installers and maintenance providers to be licensed by TCEQ and registered with the Permit & Inspection Department before doing any septic work; an unregistered installer's applications are denied. The county also keeps a contractor list for convenience, but it doesn't recommend anyone and you don't have to use it.
What rules does Wharton County add to the state's?
Several. Its septic order requires a permit regardless of acreage, so the state's 10-acre exemption doesn't apply; bars homeowner installs unless the owner is a licensed installer; requires backfill on site and every tank filled with water at inspection; allows surface spray only between 10 p.m. and 6 a.m.; sizes low-pressure dosing at bedrooms plus one; and calls for 12 inches of rock in pumped-effluent trenches. Systems that need a maintenance contract also get an affidavit recorded in the county deed records.
