Hull & Liberty County
New construction, manufactured & mobile homes

What we install in Hull
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 Liberty County soils
Advanced aerobic treatment systems
Many lots in and around Hull have clay-heavy soil or a high seasonal water table — conditions that usually call for an aerobic treatment unit with drip or spray dispersal rather than a conventional drainfield. Your free on-site soil evaluation confirms the right system before we size it.
We handle Liberty County permitting for Hull
On-site sewage facilities (OSSF) around Hull are permitted at the Liberty County level. We prepare the application, submit the soil and design documentation, and see it through approval and final inspection.
In Liberty County, the county itself issues your septic (OSSF) permit through the Liberty County Permit & Inspection Department, which is a TCEQ Authorized Agent. The application pulls together a recorded Affidavit to the Public, a two-year maintenance contract, proof of ownership (your warranty deed), a site evaluation, soil analysis, the septic design drawing, your 911 address, and the names of your installer and designer. The design has to be done by a licensed Sanitarian or professional engineer and the system installed by a licensed installer, and we handle that whole packet for you and notify the county for inspection before anything gets covered.

Soil & site conditions near Hull
Liberty County sits northeast of Houston and runs from flat coastal prairie in the south around Devers, Hull, and Daisetta up to gently rolling pineywoods in the north near Cleveland and Hardin. Across much of the county you'll find fine, slowly-permeable clay and clay-loam soils with a high water table, especially in the low-lying south, which usually fall into the least-permeable TCEQ soil classes. That's why most homes here use an aerobic unit with spray or drip dispersal rather than a conventional gravity field, but the on-site soil evaluation is what sets your exact class.

Hull septic questions
Do you install septic systems in Hull?
Yes — we design, permit, and install new on-site septic systems throughout Hull and Liberty County for new construction, manufactured, and mobile homes.
How much does a septic system cost in Hull?
Most installs land between $12,000 and $20,000 depending on your soil, 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 I need a permit for a septic system in Hull?
Yes — a new OSSF in Hull requires a Liberty County permit plus a soil/site evaluation before installation. We handle the full permitting process for you.
Who issues septic permits in Liberty County, and what does the permit cost?
The Liberty County Permit & Inspection Department issues your OSSF permit directly, since the county is a TCEQ Authorized Agent. For a residential system the county permit fee runs about $275 on the 2026 fee schedule, plus a $10 state TCEQ fee. Commercial projects cost more and a re-inspection fee can apply, so it's always smart to confirm current fees with the county before you file.
What does the Liberty County septic permit application actually require?
The county application bundles several pieces: a recorded Affidavit to the Public, a two-year maintenance contract, proof of ownership (your warranty deed), a site evaluation, a soil analysis, the septic design drawing, your 911 address, and the names of your installer and designer. The design must come from a licensed Sanitarian or professional engineer, and the install must be done by a licensed installer. We assemble this packet for you so you're not chasing paperwork.
Why do most Liberty County homes need an aerobic system instead of a standard septic field?
Much of Liberty County has fine, slowly-permeable clay and clay-loam soils with a high water table, especially in the low-lying south around Devers, Hull, and Daisetta. Those soils typically fall into the least-permeable TCEQ classes, where water doesn't drain well enough for a conventional gravity field. In that situation an aerobic treatment unit with spray or drip dispersal is the system that works, and your on-site soil evaluation confirms the right design for your parcel.
Can you install a septic system for a manufactured or mobile home in Liberty County?
Yes. A lot of properties in Liberty County, especially newer manufactured and mobile homes set on acreage around Cleveland, Dayton, and Hardin, aren't connected to city sewer and need their own on-site septic system. We size and install a new system designed for your home's bedroom count and your lot's soil class, permitted directly through the county.
Is there a minimum lot size for a septic system in Liberty County?
For subdivisions platted after June 1, 1986, the county requires a minimum of 0.5 acre if the lot is served by public water, or 1.0 acre if you're on a private well. Lot size is one piece of the picture; your site evaluation and soil analysis also shape the design. If you're not sure where your parcel lands, the county can confirm the rule for your specific lot.
How is the final septic inspection handled in Liberty County?
Before any part of the system gets covered with soil, your licensed installer notifies the county at least five days ahead so it can be scheduled for final inspection, and the system has to be approved before it's buried. The Liberty County Permit & Inspection Department offices are at 311 Travis St. in Liberty, (936) 336-4560, with an additional office in Cleveland. We coordinate the inspection timing with the county so your install passes the first time.
