What are you installing a septic system for?

We specialize in new installs for homes on rural land.

New construction, manufactured & mobile homes

Waller & Waller County

New construction, manufactured & mobile homes

Out around Waller, 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 Waller County permit, and build it to pass inspection the first time.

Out along US 290 northwest of Houston, the City of Waller straddles the Waller-Harris line, and most homes here, from the newer acreage subdivisions to the older homesteads, run on their own septic system because city sewer never made it out this far.

Septic systems in Waller

The City of Waller sits right on the Waller-Harris county line along US 290, and outside the small downtown grid most of the housing is acreage that city sewer never reached. A lot of this ground is heavy Gulf Coast prairie clay that drains slowly, so a new system here is usually an aerobic treatment unit with spray or drip dispersal rather than a plain conventional drainfield. Putting one in starts with a licensed soil evaluation and an engineered design sized to the house. Permitting runs through the Waller County Environmental Division, and the county wants a building/development permit from Road & Bridge before it'll issue the septic permit. It's the standard setup for new construction, manufactured homes, and mobile homes going up on these lots.

What we install in Waller

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.

Advanced aerobic treatment systems

Built for Waller County soils

Advanced aerobic treatment systems

A lot of the ground around Waller 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 Waller County permitting for Waller

Septic permits around Waller go through Waller 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.

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 Waller

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 septic questions

What type of septic system do most homes in Waller need?

Most lots around Waller sit on heavy prairie clay that drains slowly, which usually falls into the lower-permeability TCEQ soil classes. On that kind of ground a conventional drainfield often can't keep up, so 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 Waller lot and confirms which design actually fits.

How does the septic permit process work for a new build in Waller?

In the City of Waller, septic permits go through the Waller County Environmental Division. The county won't issue one until you've pulled a building/development permit from Waller County Road & Bridge first. After that, a licensed engineer or registered sanitarian does the soil analysis and designs the system, and that package is submitted for review before the septic permit is issued and a licensed installer can start. We can walk you through the whole sequence.

Do you install septic systems in Waller?

Yes. We install new septic systems all over Waller and Waller County — for new construction, manufactured homes, and mobile homes.

How much does a septic system cost in Waller?

Most Waller installs run between $12,000 and $20,000, depending on your soil, the system type, and how much drainfield you need. Run the instant estimate for a ballpark, and we'll give you a firm number once we've seen the lot.

Do I need a permit for a septic system in Waller?

Yes. Any new septic system in Waller needs a Waller County permit and a soil test before anyone digs — and we take care of all of it 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.
