Septic Installation
We install new septic systems for new homes and replace systems that have failed. The tank and the lateral lines are sized to the house and laid out to fit the lot.

Most homes inside the Tulsa city limits drain into the city sewer. Census maps put most of the land in ZIP 74126, on the north side, outside any city limits. Out there, a home often runs on its own septic system, on clay that drains slowly. After a wet spring, a struggling system there shows up as a soggy yard and slow drains.
Eastern Oklahoma Septic Services is based in Sapulpa, and Tulsa is part of our service area. We handle septic system installation in Tulsa for new homes and failed systems, conventional or aerobic. Repairs and septic tank pumping are part of the work too. Call or text (918) 645-0557, and we look at the job and put the quote in writing.

The City of Tulsa runs about 2,000 miles of sewer lines and 49 pumping stations. They carry wastewater to four treatment plants: Northside, Southside, Haikey Creek and Lower Bird Creek.
The city code's septic chapter keeps septic systems away from it. It bars a septic system inside a sewer district or on a lot that touches a public sewer line. It also bars one within 250 feet of such a line. So the septic homes left inside the city sit on lots farther from the sewer.
Other Tulsa ZIP codes run past the city line as well. About two thirds of the land in ZIP 74117 lies outside any city limits. In ZIP 74107, on the west side, less than a third of the land sits inside Tulsa.
The USDA soil survey maps more of Tulsa County as Dennis soil than any other kind. Dennis formed from weathered shale, and it drains somewhat poorly. In normal years, it holds water 12 to 30 inches down from December into April.
The same survey rates most of the county very limited for septic absorption fields. Its top reason is slow water movement through the soil. Shallow rock and flooding hold back other ground. By NOAA's normals, Tulsa gets about 41 inches of rain a year, and May is the wettest month.
Lateral lines are the Oklahoma name for the drain field. After a May storm, wet ground or a sewage smell over them can mean the field has quit taking water. We find the cause on site and do the lateral line repair.
The Oklahoma Department of Environmental Quality (DEQ) permits septic systems statewide, and it has a Tulsa office. Step one is a soil test, written up on the DEQ's Report for On-Site Sewage. That report sets which systems the lot may use and the minimum size of the field.
For a soil profile test, at least three holes or pits go in where the field will sit. A percolation test can only clear a site for a conventional system. State rules let aerobic septic systems with spray heads skip the soil test when sized for the heaviest clay.
Next, the DEQ issues an Authorization to Construct before a new system or a change goes in. The finished work is inspected and approved before the system goes into use. Ask for a copy of the final inspection form, because it maps each part of the system on the lot.
Tulsa County issues building permits for its unincorporated land, outside every city. Its checklist for a new home asks for the soil test for a septic tank, or a DEQ aerobic design. The Census counted 280 new single-family homes permitted in unincorporated Tulsa County in 2025.
State rules set a minimum lot size for a new septic system. Plats recorded before January 1, 1974 are exempt from it. A system on one of those older lots must still meet the construction rules.
