Your Waller County septic installer
Across Waller 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 Waller, Brookshire, Prairie View, Pattison, Pine Island — handling the soil and percolation testing and the county OSSF permitting from start to finish.
We install new septic systems across Waller County, from the city of Waller and Brookshire over to Prairie View, Pattison, and Pine Island, with the county seat at Hempstead. This is fast-growing country on the northwest side of Houston, where most new homes sit on acreage well outside any city sewer line. If you're building a new house, putting in a manufactured or mobile home, or developing a few acres out here, an on-site septic system is how your wastewater gets handled.
What we install in Waller 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 Waller 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 Waller County system is fully permitted and passes the county inspection.
Permitting in Waller County runs through the Waller County Environmental Division, the TCEQ-designated OSSF authorized agent for the whole county. There's an order to it: first you pull a building/development permit from Waller County Road & Bridge, because the county won't issue a septic permit without one. After that, a licensed professional engineer or registered sanitarian does a soil analysis and designs your system around the size of your home, and that design goes in with the soil analysis, site evaluation, and floor plan for review. Once it's approved the septic permit is issued, your system is installed by a state-licensed installer, and on an aerobic system it's covered by a state-certified maintenance provider on a two-year agreement that then continues as an annual contract.

Soil & site conditions in Waller County
Waller County sits on Houston's fast-growing northwest edge, and the ground shifts as you move across it: Gulf Coast prairie clays through the south and east, sandier claypan and post-oak-savannah soils to the north, and Brazos River bottomland near Hempstead. A lot of these parcels are heavy, slow-draining clay that falls into the lower-permeability TCEQ soil classes, which generally steers the design toward an aerobic unit with spray or drip dispersal rather than a basic conventional field. The only way to know your land for sure is a licensed on-site soil evaluation, which sets the soil class for your specific lot.

Waller County septic questions
Do I need a permit for a septic system in Waller 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 Waller 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 Waller County land are what we install most. We size and permit the right system for your home and lot.
Who issues septic permits in Waller County, and what's the fee?
Permits go through the Waller County Environmental Division, the TCEQ-designated OSSF authorized agent for the entire county. The county doesn't publish its OSSF fee schedule online, so the current permit fee is confirmed directly with the Environmental Division at environmental@wallercounty.us. A separate $10 TCEQ state fee also applies.
What's the permit process for a new septic system in Waller County?
First you pull a building/development permit from Waller County Road & Bridge, since the county won't issue a septic permit without it. Then a licensed professional engineer or registered sanitarian completes a soil analysis and designs the system for your home, and that design is submitted with the soil analysis, site evaluation, and floor plan for review. Once it's approved, the septic permit is issued and installation can begin.
Why do so many Waller County homes need an aerobic system instead of a conventional one?
Much of the county is heavy, slow-draining clay, which usually lands in the lower-permeability TCEQ soil classes. When the ground can't absorb water quickly enough for a conventional drainfield, the design typically calls for an aerobic treatment unit with spray or drip dispersal. A licensed on-site soil evaluation sets the soil class for your specific parcel and determines which design fits.
Do you install septic systems for manufactured and mobile homes in Waller County?
Yes. A new manufactured or mobile home on Waller County acreage almost always needs its own on-site septic system, and it goes through the same process as a site-built house: the building/development permit from Road & Bridge first, then the engineer or sanitarian designs the system around the home before the septic permit is issued.
Who inspects the septic system, and does it need ongoing maintenance?
Waller County Designated Representatives conduct the inspections. Your system has to be put in by a state-licensed installer, and an aerobic system is covered by a state-certified maintenance provider on a two-year maintenance agreement, which then continues as an annual contract after that.
Why does my Waller County property need a septic system at all?
Most homes in Waller County, including around Waller, Brookshire, Prairie View, Pattison, and Pine Island, sit on acreage that's beyond any municipal sewer line. With no city sewer to connect to, an on-site septic system is what treats and disposes of the home's wastewater right on your own land.
