Licensed, insured, and local. Same-day scheduling, upfront pricing, and technicians who know Ellis County systems.
Mansfield is the Ellis County seat, and its mix of historic in-town homes and fast-growing acreage subdivisions means a wide range of septic systems across the 75165 and 75167 ZIP codes. Newer builds out toward the county roads are almost all aerobic spray systems, because the Blackland clay under Mansfield will not percolate the way a conventional drain field needs. Older places closer to the courthouse square may still run conventional tanks. We service both.
Pumping for acreage tracts and ETJ properties, aerobic repair and aerator replacement, state-required maintenance inspections, installs across both the clay east side and the sandy west side, drain-field repair, and emergency backup and alarm service.
Mansfield’s rapid growth means a lot of aerobic systems installed in the last decade are now hitting the age where aerator pumps and spray heads start to fail, right on the 3-to-5-year replacement curve. If your system is that age and has not been serviced, it is worth an inspection before an alarm forces the issue. OSSF permits and aerobic transfers here go through the Ellis County permitting authority.

Mansfield is the largest city we serve, roughly 84,444 residents in 2025 against 72,602 in the 2020 census (U.S. Census Bureau), and it spans three counties: about 76 percent Tarrant, 20 percent Johnson and 4 percent Ellis. The city runs water and wastewater, so septic here is concentrated on acreage tracts and in the ETJ, especially on the less developed Johnson and Ellis county sides.
Mansfield is genuinely two different design environments inside one city, and that makes it the most interesting ground we work. Roughly 65 percent of the city is heavy Blackland clay, mostly Heiden and Houston Black over Eagle Ford shale on the east side. The other 34 percent is Cross Timbers sandy soil over the Woodbine formation on the west and southwest. The catch is that sandy does not automatically mean better. Crosstell fine sandy loam, at about 16 percent of the city, has a sandy surface over a dense, very slowly permeable clay subsoil and still rates very limited. But Konsil, Gasil and Silawa fine sandy loams in the western Woodbine pockets rate not limited under the Texas interpretation, meaning a conventional absorption field is genuinely feasible there. Those favorable soils are a minority of the city, so it comes down to a site evaluation rather than a rule of thumb.
Mansfield is not a TCEQ authorized agent. For the Tarrant County portion, which includes inside the city limits, the authority is Tarrant County Engineering Services, Environmental Division at 200 Taylor Street in Fort Worth. Worth knowing: the city’s own website still refers people to Tarrant County Public Health, but the OSSF program moved to Engineering Services. On top of that, the City of Mansfield requires county plan approval before it will issue a permit and county inspection sign-off before its own final inspection, so there are two agencies in the loop. The Ellis County portion goes to Ellis County Development. The Johnson County portion is genuinely ambiguous on paper and we confirm it by phone before filing.
These are specific to Mansfield. For statewide rules, pumping intervals and current North Texas price ranges, see our septic cost guide and the Ellis County service area page.
Both are involved. Tarrant County Engineering Services Environmental Division is the TCEQ authorized agent and reviews the OSSF. The City of Mansfield will not issue its permit until the county approves the plan, and will not sign off its final inspection until the county inspects. Note the city website still lists Tarrant County Public Health, which no longer runs the program.
Maybe, and Mansfield is one of the few places around here where that is a real question. Konsil, Gasil and Silawa fine sandy loams in the western part of the city rate not limited for absorption fields under the Texas interpretation. But Crosstell, which is about 16 percent of the city, looks sandy on top and has a dense clay subsoil underneath that fails. You cannot tell by digging a shovel down. It takes a site evaluation.
That one we verify rather than assume. Tarrant County’s coverage names Mansfield without a county qualifier, and Johnson County’s coverage is written as unincorporated area only, so the Johnson County portion of Mansfield is not cleanly assigned in the published records. We call both offices before filing so the application does not get bounced.
The soil variety. Ellis County installs are about 96 percent aerobic spray because the soil is uniformly tight clay. Tarrant County’s 2024 mix included 202 spray systems but also 60 mound or low-pressure systems, 18 absorptive, 10 leaching chamber and 9 conventional trench. That range exists because Mansfield straddles clay and sand.
