Your Fort Bend County septic installer
Across Fort Bend 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 Needville, Fulshear, Simonton, Beasley, Orchard, Kendleton — handling the soil and percolation testing and the county OSSF permitting from start to finish.
We install new septic systems across the unincorporated parts of Fort Bend County and its smaller towns, from Needville and Fulshear to Simonton, Beasley, Orchard, and Kendleton, with the county seat in Richmond. New homes on acreage out here usually aren't on city sewer, so a septic system is how they handle wastewater, and that's true for manufactured and mobile homes on these lots too. The county doesn't permit septic inside several incorporated cities, so most of our work is in the unincorporated county and the surrounding rural communities.
What we install in Fort Bend 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 Fort Bend 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 Fort Bend County system is fully permitted and passes the county inspection.
In Fort Bend County, your septic permit goes through the Fort Bend County Environmental Health Department (part of Health & Human Services). The path is straightforward: get a survey or plat of your lot, have a soil and site evaluation done, and have the system designed by a licensed professional engineer or registered sanitarian. Since March 2024, plan-review applications are submitted online only (no paper or USB drives), and the department reviews plans on Tuesdays and Thursdays. Once it's approved, the county issues your authorization to construct, and a single-family permit includes two inspections.
Local OSSF permitting authority: Fort Bend County Environmental Health Department
Typical county permit fee: About $575 (county fees change — we confirm the current amount during permitting)

Soil & site conditions in Fort Bend County
Fort Bend County sits on the Gulf Coast prairie southwest of Houston, where the soil tends to be clay-heavy and the water table sits relatively high. Under TCEQ soil-class rules, those conditions often rule out a conventional gravity drainfield, so most new homes here use an aerobic treatment unit with spray or drip dispersal instead. The on-site soil evaluation is what decides the right system for your specific lot, so no two properties are guaranteed the same answer.

Fort Bend County septic questions
Do I need a permit for a septic system in Fort Bend 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 Fort Bend 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 Fort Bend County land are what we install most. We size and permit the right system for your home and lot.
Who issues the septic permit in Fort Bend County, and what does it cost?
Permits are issued by the Fort Bend County Environmental Health Department, which is part of Health & Human Services. The single-family OSSF permit fee is around $575 on the current county fee schedule, but fees change over time, so confirm the exact amount directly with the county before you budget for it. We handle the permit submittal as part of your install.
What are the steps to get a septic system permitted here?
First you get a survey or plat of the lot, then a soil and site evaluation, and the system is designed by a licensed professional engineer or registered sanitarian. The plan-review application is submitted to the county online, the department reviews plans on Tuesdays and Thursdays, and once it's approved they issue the authorization to construct. A single-family permit includes two inspections along the way.
Why do most new septic systems in Fort Bend County have to be aerobic?
The clay-heavy soil and relatively high water table common on the Gulf Coast prairie often don't meet TCEQ's soil-class criteria for a conventional gravity drainfield. When that's the case, an aerobic treatment unit with spray or drip dispersal is the standard solution. Your soil and site evaluation confirms what your specific lot will support.
Can you install a septic system for a manufactured or mobile home in Fort Bend County?
Yes. Manufactured and mobile homes on acreage out here are typically off city sewer, so they need their own septic system just like a site-built house. The permitting and sizing follow the same county and TCEQ process, based on the home's bedroom count and your soil evaluation.
Does Fort Bend County permit septic everywhere in the county?
No. The county does not permit septic inside several incorporated cities, including Houston, Katy, Richmond, Rosenberg, Missouri City, Stafford, and Sugar Land. New septic work concentrates in the unincorporated areas and smaller towns like Needville, Fulshear, Simonton, Beasley, Orchard, and Kendleton, which is where we focus.
How long does the county take to approve a septic permit?
By statute, the county must approve or deny a complete application within 30 days. Keep in mind plan reviews are done on Tuesdays and Thursdays, and the clock runs on a complete application, so having a clean survey, soil evaluation, and a design from your engineer or sanitarian ready up front keeps things moving.
