Licensed, insured, and local. Same-day scheduling, upfront pricing, and technicians who know Ellis County systems.
Cedar Hill 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 Cedar Hill 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 and cleaning for the acreage lots, aerobic repair and aerator replacement, state-required maintenance inspections, tank abandonment and inspection when a property ties into city sewer, drain-field repair on the escarpment, and emergency response.
Cedar Hill’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.

Cedar Hill is a built-out suburb of roughly 50,000, about 91 percent in Dallas County with the southern edge crossing into Ellis County. Growth is slow here compared to the towns south of it, and most of the city is on sewer. Septic in Cedar Hill is a large-lot and acreage story: the city authorized 7 new systems in 2024 and 7 in 2025, every one of them aerobic spray.
Cedar Hill sits on the White Rock Escarpment, at around 800 feet one of the highest points in the region, and the soil reflects that. USDA mapping shows Eddy phases across roughly 35 percent of the city, plus Stephen, Austin, Dalco and Vertel. Eddy and Stephen are shallow soils over Austin Chalk. Dalco, Vertel, Ferris and Heiden are slowly permeable shrink-swell clays. Every one of them is rated very limited for a conventional septic absorption field. On the ridges the limit is depth to rock, in the lowlands it is percolation, and there is not much ground in Cedar Hill that avoids both. Because the north end drains into the Joe Pool Lake watershed, a failing system here is a water quality issue as well as a homeowner problem.
The City of Cedar Hill is its own TCEQ authorized agent for both the Dallas County and the Ellis County portions of the city, so the permit comes from Cedar Hill Environmental Services at 285 Uptown Boulevard rather than from either county. Cedar Hill also runs two local rules that are stricter than the state: a new OSSF requires a minimum 1-acre lot, and no new OSSF is allowed where any part of the lot is within 200 feet of an existing sanitary sewer unless you have a written denial of service or an infeasibility determination. Outside the city limits it is Dallas County Health and Human Services or Ellis County Department of Development depending on the side.
These are specific to Cedar Hill. For statewide rules, pumping intervals and current North Texas price ranges, see our septic cost guide and the Ellis County service area page.
Only under specific conditions. City rules require a minimum 1-acre lot for a new OSSF, and prohibit one if any part of the lot is within 200 feet of an existing sanitary sewer line unless you have written denial of service or an infeasibility determination from the city. In practice that limits new systems to acreage away from the sewered areas, which is why the city only permitted 7 in 2024.
The City of Cedar Hill, for addresses inside the city limits, on both the Dallas County and Ellis County sides. Cedar Hill holds its own TCEQ authorized agent designation. Outside the limits it goes to Dallas County Health and Human Services or Ellis County Development depending on the side of the line.
It has to be formally abandoned, not just left in the ground. The city requires the tank be pumped out and then crushed or filled with sand, with an inspection to confirm it. We do that work and coordinate the inspection.
The north and northeast side of Cedar Hill drains into the Joe Pool Lake watershed, so a failing system is a documented water quality concern rather than just a nuisance. Combined with the shallow soil over chalk on the escarpment, that is why site evaluations and maintenance compliance get real attention on this side of town.
