City sewer mains cover the core of Oklahoma City, but drive out to the acreages around Choctaw, Harrah, Jones, Luther, Arcadia and the far edges of Edmond, south toward Norman, Noble and Lexington, or west through Yukon, Mustang, Piedmont and El Reno, and plenty of houses treat their own wastewater on the lot. This site is a plain guide to those systems: when to pump, what an aerobic unit needs, what the state's rules say, and how to get a local septic contractor out to the property.
The Oklahoma Department of Environmental Quality recognizes four kinds of home systems: a septic tank with subsurface lateral lines, a lagoon, an evapotranspiration/absorption (ET/A) field, and an aerobic treatment system that sprays or drips treated water over the yard (DEQ sewage treatment). The two that homeowners ask about most:
Which one a lot can use is decided by its soil. DEQ's design-only option assumes the heaviest clay class and is limited to aerobic spray or lagoon systems, so on tight clay an aerobic unit is often the option left on the table.

| No idea when the tank was last emptied | Septic tank pumping and cleaning, then the pumping schedule guide. |
| Red light or buzzer on a control box | A high-water or air-pump alarm. See aerobic service, or septic repair if it's a lift station. |
| Drains slow, toilets gurgle, smell in the bathroom | Septic repair and backups: checks to make before the truck arrives. |
| Soggy patch or sewage odor over the lateral lines | Effluent surfacing, which Oklahoma's rules require the owner to fix. See repairs. |
| Building on raw land or replacing a dead system | New septic system installation: the 581 report, soil tests and the DEQ authorization. |
| Wondering what it'll run | The septic cost guide lists DEQ's base fees and what moves a contractor's quote. |
Two different credentials matter. Anyone in the business of pumping and hauling septage needs an annual DEQ license, and every truck carries "DEQ" plus its registration number in letters at least four inches tall on both sides of the tank (OAC 252:645). People who build or modify systems are DEQ-certified installers under OAC 252:641; since November 1, 2025, anyone without that certification can put in only one system a year (DEQ FAQ). Our plain-English DEQ rules guide explains both and how to look a company up.
No. This is a referral line. We hand your request to an independent septic company that serves your area, and that company quotes the job and does the work.

Around here people use the two phrases for the same visit: a vacuum truck empties the tank. The pumping page explains what a thorough visit includes.
