Bellville & Austin County
New construction, manufactured & mobile homes

Septic systems in Bellville
San Felipe was the Austin County seat until 1848, when it moved to Bellville, named for the Bell family; the county itself was organized in 1837, during the Republic of Texas. The City of Bellville owns its electric, gas, water, wastewater and sanitation services, runs a treatment plant on West Hickory Street, and charges $630 for a four-inch sewer tap. Its public web map shows the gravity sewer stopping at or just past the city limits. Inside the city, Austin County's septic program doesn't apply, and TCEQ's own listing names Bellville among the cities its Houston regional office covers when no local agreement exists. Around town, Austin County Planning & Development at One East Main handles septic permits, and the order matters: a development permit or exemption certificate first, with a 911 address letter, then the septic permit, signed by the property owner, at $275 for a conventional system or $375 for an aerobic one, doubled if work starts first. The address and permits must be posted at the final inspection, and the permit is good for one year. The county requires a permit regardless of tract size and a one-acre minimum residential lot even with public water. One local footnote: the Sealy soil series was described from a spot about three miles north of downtown Bellville.
Septic conditions around Bellville
We ran 35 spots within 5 miles of downtown Bellville through the same public data our free land check uses: the USDA soil survey, FEMA's flood maps and the National Wetlands Inventory. Here is what they show for a new septic system.

One of the 35 spots falls on open water (a lake, river or bay) and is left out of the flood and wetland counts, which cover land only.
Most of the ground around Bellville won't take a standard gravity drainfield: water moves through the soil too slowly. Plan on an aerobic system with spray or drip dispersal, from $11,950 installed. The two soil borings on your own lot make the final call. Prices cover the system and installation; the site evaluation, design and county permit are quoted separately.
4 of the 34 spots on land are in a FEMA high-risk flood zone. A lot there adds floodplain rules to the septic design and usually a county floodplain permit, so check your lot's zone early.

A map sample isn't your lot. The USDA soil survey maps the landscape at 1:24,000, and Texas requires a licensed site evaluator or engineer to evaluate every tract before a permit (30 TAC §285.30). Run your own address through the free land check to see what the maps show for your lot.

What we install in Bellville
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 Austin County soils
Advanced aerobic treatment systems
The USDA soil survey rates most of the ground around Bellville "very limited" for a standard drainfield: it drains too slowly, holds a high water table part of the year, or both. 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 on-site soil test tells us exactly what your lot can take.

Bellville septic questions
What does Austin County require before a septic permit?
A development permit or exemption certificate, which has to come before anything is moved onto or built on the property, along with a 911 address letter from the Austin County Emergency Communication District. Then the septic application goes in with the site evaluation, the design if it's not a standard system, a maintenance agreement for aerobic systems and a notarized affidavit, signed by the property owner, not an agent.
How big does a septic lot have to be around Bellville?
At least one acre. Austin County's septic order sets a one-acre minimum for every residential lot, whether it's on a private well or public water, which is stricter than the state's half acre with public water. The county's 2025 subdivision rules also call for 150 feet of paved public street frontage on a new septic lot.
Does Bellville's city sewer reach beyond the city?
Barely. The city's public web map shows its gravity sewer lines ending at or just past the city limits (the mapped data dates from 2018), so most land around Bellville needs its own septic system, permitted by Austin County.
Will I need an aerobic septic system in Bellville?
Probably. Of the 34 spots we checked within 5 miles of downtown Bellville, 34 point to an aerobic system, mainly because water moves through the soil too slowly. Aerobic systems start at $11,950 installed (the site evaluation, design and permit are quoted separately). The two soil borings on your lot make the final call.
Is Bellville in a flood zone?
Parts of the area are. 4 of the 34 spots on land we checked within 5 miles of downtown Bellville are inside a FEMA Special Flood Hazard Area (the 100-year floodplain). Your own lot's zone is what counts, so run the address through our free land check before you buy or design.
Do you install septic systems in Bellville?
Yes. We install new septic systems on land in and around Bellville and across Austin County — for new construction, manufactured homes, and mobile homes. Inside city limits that have city sewer, you'll usually connect to the sewer instead.
How much does a septic system cost in Bellville?
Most Bellville installs run between $8,000 and $13,950 — $8,000 for a conventional system where the soil allows it, $11,950 for an aerobic spray system, and $13,950 for an aerobic system with drip dispersal. The soil evaluation (perc test), the engineered design, and the county permit are quoted separately. 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 Bellville?
Yes. Every new septic system needs a permit and a soil evaluation before anyone digs. Around Bellville the permit usually comes from Austin County, and we take care of all of it for you.
