What are you installing a septic system for?
We specialize in new installs for homes on rural land.
El Campo & Wharton County
New construction, manufactured & mobile homes
Out around El Campo, homes beyond the reach of city sewer 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 Wharton County permit, and build it to pass inspection the first time.
Get My Free EstimateEl Campo, a railroad town by 1890 and incorporated in 1905, is the largest city in Wharton County. City sewer mains run almost entirely inside the city limits; land beyond them needs a septic system permitted by Wharton County.
Septic systems in El Campo
El Campo was "an exciting new railroad town" by 1890, in the words of a state historical marker, and local bankers led the push to incorporate it in 1905; rice and oil built its economy, and with 12,350 people in the 2020 census it's the largest city in Wharton County. The city treats its wastewater at a plant on East Thompson Street, permitted for about 2.6 million gallons a day, through roughly 90 miles of mains and 15 lift stations, and its own public sewer map shows those mains running almost entirely inside the city limits. Land beyond them, including the city's one-mile extraterritorial jurisdiction, generally needs a septic system: the city's plat application lists septic tanks as a sanitary option for land in the city or the ETJ, and subdivisions in the ETJ follow El Campo's subdivision policy. One rule to plan around: neither the city nor any utility in the city or ETJ will connect land until there's an approved, recorded subdivision plat. Outside the city, Wharton County's Permit & Inspection Department issues the septic permit under the county's order, which requires a permit at any acreage; inside the city limits the county's program doesn't apply, so for an in-city lot we check with the city first.
Septic conditions around El Campo
We ran 35 spots within 5 miles of downtown El Campo 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.

Most of the ground around El Campo won't take a standard gravity drainfield: water moves through the soil too slowly and water ponds on it after rain. 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.
11 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 El Campo
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 El Campo "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.

El Campo septic questions
Does El Campo's sewer reach beyond the city limits?
Very little. The city's own public map of sewer mains shows them running almost entirely inside the city limits, so land in the one-mile extraterritorial jurisdiction and beyond generally needs a septic system. The city's plat application lists septic tanks as an option for land in the city or the ETJ.
Who issues septic permits around El Campo?
Outside the city limits, Wharton County's Permit & Inspection Department, at 315 E. Milam Street in Wharton; call ahead, since the inspector is often out on inspections. The county's program covers unincorporated land and East Bernard, not El Campo itself, so for a lot inside the city we check with the city first.
Do I need a recorded plat before I can get utilities near El Campo?
Yes. El Campo's subdivision rules say neither the city nor any public utility in the city or its ETJ will serve or connect land with water, sewer or other service until there's an approved, recorded subdivision plat. Subdivisions in the ETJ also need a guarantee of performance for water, wastewater and drainage before the city forwards the plat to the county.
Will I need an aerobic septic system in El Campo?
Probably. Of the 35 spots we checked within 5 miles of downtown El Campo, 35 point to an aerobic system, mainly because water moves through the soil too slowly and water ponds on it after rain. 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 El Campo in a flood zone?
Parts of the area are. 11 of the 35 spots we checked within 5 miles of downtown El Campo are inside a FEMA Special Flood Hazard Area (the 100-year floodplain), including 1 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 El Campo?
Yes. We install new septic systems on land in and around El Campo 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 El Campo?
Most El Campo 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 El Campo?
Yes. Every new septic system needs a permit and a soil evaluation before anyone digs. Around El Campo the permit usually comes from Wharton County, and we take care of all of it for you.
