Aerobic Systems
We install aerobic septic systems with spray heads on lots where a conventional system will not work. We also replace failed aerobic units and repair the parts that wear out.

A new septic system starts with a soil test and ends with a tank and lateral lines in the ground. Eastern Oklahoma Septic Services handles septic system installation for new homes and septic system replacement when an old system fails. Lateral lines are what Oklahoma calls the drain field, also known as a leach field.
We are based in Sapulpa and work about 40 miles around it, across Creek County and the Tulsa area. We install conventional systems, and aerobic systems where the soil calls for one. See every line of work we do at septic system installation in Sapulpa. Call or text (918) 645-0557, and we look at the job and put the quote in writing.

The Oklahoma Department of Environmental Quality (DEQ) sets the rules for septic systems statewide. Its process for a new system has three steps. 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 their minimum size.
For a soil profile test, at least three holes or pits are dug where the lateral lines would go. The soil is read in 6-inch layers to at least 4 feet, unless heavy clay or rock stops the hole. Only the DEQ or a soil profiler on its list may run this test.
Step two is the Authorization to Construct, the DEQ's go-ahead to build a new system or change an old one. The local DEQ environmental specialist reviews the soil report before issuing it. Step three is an inspection before the system is covered or put to use. The final inspection form records where each part sits on the lot.
Oklahoma's rules size a system by bedrooms. A home with four bedrooms or fewer needs a septic tank of at least 1,000 gallons. Each bedroom past four adds 250 gallons. The DEQ's homeowner guide suggests a tank 20 percent larger when the kitchen has a garbage disposal.
Bedrooms and soil together set how long the lateral lines run. The DEQ estimates that about 60 percent of Oklahoma soils suit a conventional system. If the test rates the soil as Group 5, the heaviest clay, a conventional system is not allowed. The rules allow an aerobic septic system with spray heads in every soil group.
The rules set each trench at 24 inches wide and 18 to 30 inches deep, with a level bottom. Trenches sit at least 8 feet apart, center to center. The lines need at least 2 inches of fall below the tank outlet, unless a pump moves the water. We lay out the tank and the lines to fit those numbers on your lot.
New neighborhoods keep going up north of Tulsa around Owasso and Collinsville, and out by Broken Arrow. On a lot with no city sewer, the house needs its own system. Before the build, keep fill dirt off the spot that was soil tested. If more than 6 inches of fill lands there, the local DEQ office decides whether to test again. Many of those lots get a storm shelter too, and we place the shelter and the system so neither crowds the other: see storm shelter installation.
Septic system replacement follows the same steps as a new build. We check the old tank before we quote, since a tank must not leak or let water in. When the tank is sound and only the lines failed, lateral line repair may be the whole job. The rules still count new lateral lines as a new installation, even when the old tank stays.
After the install, mark the tank lid and keep the final inspection report. A call to OKIE811 does not get septic lines marked. Keep cars and trees away from the lateral lines, and send roof water elsewhere. The DEQ's homeowner guide puts septic tank pumping at every 3 to 5 years under average use.
