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.

Skiatook straddles the Tulsa County and Osage County line, where open prairie meets the oak hills around Skiatook Lake. Homes on city sewer send their wastewater to the city's treatment plant. A home with no sewer line to tie into treats its wastewater on its own lot. Around Skiatook, two kinds of ground give those systems trouble: slow-draining clay and shallow sandstone.
Eastern Oklahoma Septic Services is based in Sapulpa, and Skiatook is part of our service area. For septic system installation in Skiatook, we handle new septic systems and replacements on both sides of the county line. Where the soil test rules out lateral lines, we install aerobic septic systems with spray heads. Call or text (918) 645-0557, and we look at the job and put the quote in writing.

The City of Skiatook runs its own water and sewer department. A home past the reach of its sewer lines needs its own system on the lot. That can be a septic tank with lateral lines, or an aerobic system. Lateral lines are the Oklahoma name for the drain field, also called a leach field.
Most of Skiatook's people live on the Osage County side. Downtown sits in Tulsa County, yet Census estimates put about 7 in 10 residents in the Osage County part. The 2020 Census counted 8,450 people in Skiatook, and the July 2025 estimate is 8,960. SH 20 runs through town as W.C. Rogers Boulevard, and SH 11 follows Cincinnati Avenue south toward Sperry.
Census survey data puts single-family houses at about 81 percent of Skiatook's housing. The median home was built in 1989, and about 4 in 10 date from 2000 or later. Census permit data shows 170 new single-family homes authorized in town from 2022 through 2025. Unincorporated Osage County authorized 317 more in those years, across the whole county.
The NRCS soil survey maps much of Skiatook on deep prairie soils, such as the Dennis and Parsons series. Both formed from shale and clay, and both are somewhat poorly drained. The survey rates them very limited for septic tank absorption fields, since water moves through them slowly. A wet layer can also sit within a few feet of the surface for part of the year.
West of town, the land turns to the post oak and blackjack oak hills around Skiatook Lake. There the survey maps Bigheart soils, a shallow layer over sandstone, mixed with rock outcrop. Those rate very limited too, mostly for depth to bedrock. Slope adds a second limit on the steeper lots.
A soil map is a guide, and the DEQ soil test on the lot decides the system. Under state rules, the heaviest clay, Group 5, rules out a conventional system. An aerobic unit with spray heads is allowed in every soil group. After its first two years, DEQ rules make the owner responsible for regular aerobic system maintenance.
The Oklahoma Department of Environmental Quality (DEQ) permits septic systems statewide, inside the city limits and out in the county. Step one is the Report for On-Site Sewage, known as the 581. It records the soil test and sets which systems the lot may use.
For an aerobic spray system, the DEQ also allows a Design Only report. It works from the property's location and sizes the system for the heaviest clay. Step two is the Authorization to Construct, which the DEQ issues before a new system goes in. The DEQ's local environmental specialist for the area handles the file.
Step three is an inspection before the system is covered or put to use. Inside the city limits, the city's permits page lists a residential building permit and a lot split application. Those cover the house and the land, and the septic system still follows the DEQ path. Ask the city about your lot before work starts.
Skiatook Lake sits on Hominy Creek about 5 miles west of town, and the Army Corps of Engineers runs it. The state's Lakes of Oklahoma guide lists the lake at 10,190 acres, with 187 miles of shoreline. The Corps built it for flood control and water supply, among other uses.
That state listing matters for septic work. Under DEQ rules, a listed lake gets a protection area in two zones, measured from its highest normal pool level. Zone 1 runs 300 feet out, and Zone 2 runs 1,320 feet. Inside either zone, a percolation test cannot be used to site a system.
Within Zone 1, lateral lines or a spray field need a nitrogen-reducing treatment unit ahead of them. That unit must be tested to a national standard. Listed streams get the same zones, measured from the stream bed. For a lot near Hominy Creek or Bird Creek, ask the DEQ whether those zones apply.
