What are you installing a septic system for?
We specialize in new installs for homes on rural land.
Huntsville & Walker County
New construction, manufactured & mobile homes
Out around Huntsville, most homes sit on land city sewer never reached, so they run on their own septic system. We install new systems for new builds, manufactured homes, and mobile homes. We run the soil and perc testing, pull the Walker County permit, and build it to pass inspection the first time.
Get My Free EstimateHuntsville is the county seat and the biggest town for fifty miles of I-45, but its sewer lines stop at the city's edge. The acreage homes, cabins, and new builds in the piney country around town — out toward the state park and the national forest — all run on their own septic systems.
Septic systems in Huntsville
Septic projects around Huntsville start with Walker County's checklist. The county won't take an application until the property has a valid 9-1-1 address (getting one takes a week or two), and the packet needs the recorded deed, a scaled site drawing, and a floor plan. If your land falls inside Huntsville's extraterritorial jurisdiction, the city's certificate of compliance comes before the county permit — we check where your parcel falls on day one so nothing gets filed out of order. The permit itself is one of the region's cheapest at $210 for a single-family residence. The timberland soils are the design driver: sands and fine sandy loams over slowly permeable clay, often with seasonal wetness, which usually points to an aerobic system with spray or drip. We run the checklist, the permit, and the install end to end.
What we install in Huntsville
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.
Built for Walker County soils
Advanced aerobic treatment systems
A lot of the ground around Huntsville is heavy clay, and in spots the water table sits high part of the year. On lots like that a standard gravity drainfield won't pass, so you'll need an aerobic system with drip or spray dispersal. We don't guess at it — the free soil test tells us exactly what your lot can take.
We handle Walker County permitting for Huntsville
Septic permits around Huntsville go through Walker County, not the state. We put the application together, turn in the soil and design paperwork, and stay on it through approval and the final inspection — so you're not the one chasing the county.
In Walker County, septic permits run through the county's Planning & Development office — its On-Site Wastewater division at 1313 University Avenue in Huntsville. The county asks for its groundwork up front: the property needs a valid 9-1-1 address (allow up to a couple of weeks through the county's addressing office if it doesn't have one), a copy of the recorded deed, a scaled site drawing, and a floor plan of the structure. From there it's the standard TCEQ 30 TAC Chapter 285 sequence — a licensed site evaluator's soil and site evaluation, the design submittal, the county's Authorization to Construct, installation by a TCEQ-licensed installer, and inspection before final approval. Inside Huntsville's ETJ, the city's certificate of compliance comes first. We run that checklist for you so nothing stalls the job.

Soil & site conditions near Huntsville
Walker County is East Texas timberland: upland forest soils that are typically sands and fine sandy loams sitting over slowly permeable clay subsoil, with alluvial loams along the Trinity River drainages and creek bottoms. The surface layer takes water fine — it's the tight clay underneath and the seasonal wetness that limit a conventional drainfield on many sites. That's why aerobic systems with spray or drip dispersal are commonly specified here, with the occasional deep-sand ridge grading out better. The on-site soil evaluation sets the class and the design for your lot.

Huntsville septic questions
What does Walker County require before a septic application near Huntsville?
Three things trip people up: a valid 9-1-1 address for the property (allow 7–10 business days to get one), a copy of the recorded deed, and a scaled site drawing plus floor plan. Inside Huntsville's ETJ, a city certificate of compliance comes first. We assemble the whole packet as part of the job.
How much does a septic system and permit cost near Huntsville?
The Walker County single-family OSSF permit is $210 on the county's published fee sheet (aerobic systems record a small affidavit with the County Clerk too). The system itself is flat-priced: $9,000 conventional where the soil allows one, $13,500 aerobic with spray, or $15,500 aerobic with drip, installed.
Do you install septic systems in Huntsville?
Yes. We install new septic systems all over Huntsville and Walker County — for new construction, manufactured homes, and mobile homes.
How much does a septic system cost in Huntsville?
Most Huntsville installs run between $9,000 and $15,500 — about $9,000 for a conventional system where the soil allows it, $13,500 for an aerobic spray system, and $15,500 for an aerobic system with drip dispersal. Run the instant estimate for a ballpark, and we'll confirm the exact number once we've seen the lot.
Do I need a permit for a septic system in Huntsville?
Yes. Any new septic system in Huntsville needs a Walker County permit and a soil test before anyone digs — and we take care of all of it for you.
Who issues septic permits in Walker County, and what does the permit cost?
Walker County Planning & Development's On-Site Wastewater division at 1313 University Avenue in Huntsville, (936) 436-4939, issues OSSF permits. The single-family residential permit fee is $210 on the county's published fee sheet, and an aerobic system also records an Affidavit to the Public with the County Clerk (about $26). We confirm the current figures when we file.
What does the county need before it will take my septic application?
Three things trip people up: the property must have a valid 9-1-1 address (getting one takes roughly 7–10 business days through the county's addressing office), and the application needs a copy of the recorded deed, a scaled site drawing, and a floor plan of the structure. After that it's the standard sequence — site evaluation, design, Authorization to Construct, licensed installation, and inspection. We assemble the whole packet for you.
My property is near Huntsville — does the city get involved?
If your lot falls inside Huntsville's extraterritorial jurisdiction (ETJ), the county requires a City of Huntsville certificate of compliance before it will issue the septic permit. Outside the ETJ, it's purely a county matter. We check where your parcel falls at the start so the right approvals happen in the right order.
Why do many Walker County lots need an aerobic system?
The timberland soils here are sands and sandy loams over slowly permeable clay, often with seasonal wetness. The surface drains fine, but water stalls on that clay subsoil, which fails the TCEQ criteria for a conventional gravity drainfield on many sites. An aerobic treatment unit with spray or drip dispersal is the design that passes — and the on-site soil evaluation is what decides for your lot.
Can you install a septic system for a manufactured or mobile home in Walker County?
Yes. Manufactured homes on acreage around New Waverly, Riverside, Dodge, and the rest of the county need their own permitted on-site system, and the county process is identical to a site-built house. We handle the 9-1-1 address check, the evaluation and design, the permit, and the licensed install end to end.
Who inspects the system, and when?
Walker County's On-Site Wastewater division inspects the system before it's covered, after installation by a TCEQ-licensed installer. The county's permit windows run weekday mornings and afternoons, and we coordinate the inspection timing so your system is approved and buried without sitting open.
