Get My Free EstimateTucked near the junction of FM 359 and FM 3346 just south of Hempstead in central Waller County, the town of Pine Island is a low-density rural community where homes on larger lots and farmland parcels rely on on-site septic systems for wastewater.
What we install in Pine Island
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 Waller County soils
Advanced aerobic treatment systems
Many lots in and around Pine Island 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 Waller County permitting for Pine Island
On-site sewage facilities (OSSF) around Pine Island are permitted at the Waller County level. We prepare the application, submit the soil and design documentation, and see it through approval and final 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 near Pine Island
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.

Pine Island septic questions

Do I need a permit for a septic system in Pine Island?
Yes — a new OSSF in Pine Island requires a Waller County permit plus a soil/site evaluation before installation. We handle the full permitting process for you.
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.
