What are you installing a septic system for?
We specialize in new installs for homes on rural land.
Bedias & Grimes County
New construction, manufactured & mobile homes
Out around Bedias, 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 Grimes County permit, and build it to pass inspection the first time.
Get My Free EstimateBedias is sandy post-oak country in the far north of Grimes County, quiet ranch land off Highway 90. Homes and hunting places out here sit on big tracts with no utilities but the power line, which makes an on-site septic system part of making any of it livable.
What we install in Bedias
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 Grimes County soils
Advanced aerobic treatment systems
A lot of the ground around Bedias 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 Grimes County permitting for Bedias
Septic permits around Bedias go through Grimes 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.
In Grimes County, septic permitting runs through the Grimes County Environmental Services Division, headquartered at the county annex in Anderson. The county's own published sequence starts with a certified site evaluator doing the soil and site evaluation, a system design built on those results, and the permit application filed with the fee. The county issues an Authorization to Construct before any dirt moves, the system must be built by a TCEQ-licensed installer, and a county representative inspects the finished install before issuing the Notice of Approval. On aerobic systems, a notarized Affidavit to the Public also gets recorded with the County Clerk. One thing new for 2026: the county now requires its Certificate of Compliance before permanent electric service can be connected to a new structure in the unincorporated county, so the septic permit isn't a detail you can leave for later — we sequence it so your power isn't held up.

Soil & site conditions near Bedias
Grimes County sits in the Post Oak Savannah, and the ground here has a split personality: gray, fine sandy loam on top that looks friendly, sitting over a dense clay pan that barely lets water through. That claypan is what sinks a conventional drainfield on many lots — water perches on the clay instead of soaking away. Aerobic systems with spray or drip dispersal are the common answer across the county, with the bottomland clay loams along the creeks telling a similar story. The on-site soil evaluation sets your lot's actual class and the design that will pass.

Bedias septic questions
Do you install septic systems in Bedias?
Yes. We install new septic systems all over Bedias and Grimes County — for new construction, manufactured homes, and mobile homes.
How much does a septic system cost in Bedias?
Most Bedias installs run between $9,000 and $15,500 — about $9,000 for a conventional system where the soil allows it, $13,500 for an aerobic spray system, and $15,500 for an aerobic system with drip dispersal. Run the instant estimate for a ballpark, and we'll confirm the exact number once we've seen the lot.
Do I need a permit for a septic system in Bedias?
Yes. Any new septic system in Bedias needs a Grimes County permit and a soil test before anyone digs — and we take care of all of it for you.
Who issues septic permits in Grimes County, and what does the permit cost?
The Grimes County Environmental Services Division issues OSSF permits, from the county annex at 1170 CR 280 in Anderson, (936) 873-4495. The residential permit fee is $420 on the county's current schedule, and an aerobic system also records a notarized Affidavit to the Public with the County Clerk (about $25 for the first page). We confirm current figures when we file.
What are the steps to get a septic system permitted in Grimes County?
The county publishes a straightforward sequence: a certified site evaluator performs the soil and site evaluation, a design is prepared from it, and the application is filed with the fee. The county issues an Authorization to Construct before work starts, a TCEQ-licensed installer builds the system, and a county representative inspects it before issuing the Notice of Approval. We handle every step as your installer.
Is it true I can't get permanent power without the septic being approved?
Effectively, yes. Since January 2026, permanent electric service can't be connected to a structure in unincorporated Grimes County until the county issues its Certificate of Compliance — and an approved, permitted septic system is part of getting there. We sequence the septic permit and inspection so your electrical hookup isn't the thing waiting on it.
Why do so many Grimes County lots need an aerobic system?
The Post Oak Savannah soils here are typically a fine sandy loam sitting on a dense, nearly impervious clay pan. Water perches on that clay instead of soaking through, which fails the TCEQ criteria for a conventional gravity drainfield on many sites. An aerobic treatment unit with spray or drip dispersal is the design that works, and your on-site soil evaluation confirms it for your lot.
Can you install a septic system for a manufactured or mobile home in Grimes County?
Yes — manufactured homes on acreage around Navasota, Iola, Bedias, Plantersville, and Todd Mission are a big part of what we do. The county process is identical to a site-built house: site evaluation, design, Authorization to Construct, licensed installation, and the county inspection, plus the recorded affidavit on aerobic systems.
Do you cover the whole county, including the Navasota area?
Yes. We install throughout Grimes County — Anderson, Navasota and its outskirts, Bedias, Iola, Richards, Shiro, Roans Prairie, Carlos, Singleton, Plantersville, and Todd Mission. If your property is outside a city sewer service area anywhere in the county, we can size, permit, and install your system.
