Wharton & Wharton County
New construction, manufactured & mobile homes

Septic systems in Wharton
Wharton was founded as the seat of Wharton County in April 1846, on land from the grant of William Kincheloe, one of Stephen F. Austin's Old Three Hundred; the courthouse on the east bank of the Colorado was finished in 1889, and the city incorporated in 1902. The city runs two treatment plants, and its 2018 comprehensive plan found no area inside the city limits without sewer service. The code makes the public sewer the default unless the Public Works Director grants an exception (Sec. 86-13), and a homestead customer inside the city gets up to 200 feet of line extension at no charge (Sec. 86-15). Around the city, Wharton's extraterritorial jurisdiction reaches a mile out: within half a mile, the city's subdivision rules apply in full and the developer provides the water and sewer lines, while from half a mile to a mile the code allows a variance for private sewage systems backed by a city-approved percolation test (App. A §3.5). Outside the city, Wharton County's Permit & Inspection Department at 315 E. Milam Street issues septic permits; the county's program covers unincorporated land and East Bernard, not the City of Wharton. Flooding is part of the picture here: after Hurricane Harvey in 2017, the Colorado flooded parts of the city for days.
Septic conditions around Wharton

Most of the ground around Wharton won't take a standard gravity drainfield: water moves through the soil too slowly and parts of it flood. 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.
21 of the 35 spots 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 Wharton
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 Wharton County soils
Advanced aerobic treatment systems
The USDA soil survey rates most of the ground around Wharton "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.

Wharton septic questions
Can I use septic inside Wharton city limits?
Rarely. The city's 2018 comprehensive plan found no area inside the city limits without sewer service, and the code requires the public sewer to be used unless the Public Works Director grants an exception (Sec. 86-13). Land annexed since 2018 may differ, so we check sewer availability for your parcel with the city.
What are Wharton County's septic rules outside the city?
Stricter than the state's in a few ways. The county requires a permit regardless of acreage, so there's no 10-acre exemption; spray systems may only run between 10 p.m. and 6 a.m.; installers must be licensed by TCEQ and registered with the county's Permit & Inspection Department; and low-pressure dosing systems are sized at bedrooms plus one. Lots need at least an acre with their own well, or half an acre on public water.
Can I subdivide land near Wharton into septic lots?
It depends on the distance from the city. Within half a mile of the city limits, Wharton's subdivision rules apply in full and the developer must provide water and sewer lines. From half a mile to a mile out, the code allows a variance for private sewage systems with a city-approved percolation test on each site (App. A §3.5), and the septic permit itself comes from Wharton County.
Will I need an aerobic septic system in Wharton?
Probably. Of the 35 spots we checked within 5 miles of downtown Wharton, 35 point to an aerobic system, mainly because water moves through the soil too slowly and parts of it flood. 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 Wharton in a flood zone?
Parts of the area are. 21 of the 35 spots we checked within 5 miles of downtown Wharton are inside a FEMA Special Flood Hazard Area (the 100-year floodplain), including 4 in the regulatory floodway. 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 Wharton?
Yes. We install new septic systems on land in and around Wharton and across Wharton 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 Wharton?
Most Wharton 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 Wharton?
Yes. Every new septic system needs a permit and a soil evaluation before anyone digs. Around Wharton the permit usually comes from Wharton County, and we take care of all of it for you.
