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.

Collinsville grew from 7,881 people in the 2020 Census to an estimated 9,956 in 2025. Inside the city limits, homes near a sewer line tie into it. Out on the ranch land around town, each home treats its own wastewater on the lot. Most soil around Collinsville has a clay subsoil that stays wet from December into spring, when tired systems show it.
Eastern Oklahoma Septic Services is based in Sapulpa, and Collinsville is part of our service area. We put in new systems for homes going up around Collinsville, and we replace failed ones. Our septic system installation work covers conventional tanks with lateral lines and aerobic systems with spray heads. Call or text (918) 645-0557, and we look at the lot and put the quote in writing.

The Collinsville Municipal Authority runs the town's water and sewer, with about 2,900 sewer connections. The city code sets the line at 300 feet. A home within 300 feet of a sewer line it can reach goes on the sewer.
A Collinsville mailing address can sit well outside the city. Census maps give the 74021 ZIP code about 67 square miles of land. The city limits cover about 8 of them, and about 13 sit east of the county line in Rogers County.
Tulsa County's land use plan calls much of Collinsville's planning area ranch and cattle land. The plan describes those farm tracts as areas without sanitary sewer service. Some of that land is split into county plats, tracts of 10 acres or more on private roads. A home on that kind of land needs its own system.
On NRCS soil maps, Dennis soils cover more of Collinsville than any other kind. Their subsoil runs 28 to 50 percent clay. NRCS reports a perched water table 12 to 30 inches down from December to April in normal years.
Okemah and Eram soils, also common in town, hold water 1 to 3 feet down through winter and spring. On higher ground, Coweta soils sit on soft sandstone just 10 to 20 inches down. NRCS rates nearly all the soil mapped in town as very limited for septic absorption fields.
State rules do not allow a conventional field of lateral lines in the heaviest clay, called Group 5 soil. Spray from an aerobic unit is allowed in every soil group. So on a heavy clay lot, the soil test can point to an aerobic septic system with spray heads.
The Oklahoma Department of Environmental Quality, or DEQ, approves septic systems in Tulsa County and Rogers County alike. Inside the limits, the city handles the building permit for the house. The septic approval still comes from the state.
It starts with a soil test where the field will go. A soil profile test bores at least three holes and logs the soil in six-inch layers. The results go on DEQ's Report for On-Site Sewage, which sets the systems the lot may use.
Next, the DEQ environmental specialist for the area reviews that report. DEQ then issues an authorization to construct, which has to come before any new system goes in. Last, the system is inspected and approved before it is covered or put to use.
Several recent plats sit on the west side of town, between US 75 and Memorial Drive. Hollow Creek Extended II was recorded in 2025 and Cooper Ranch I in 2024, both on larger lots. Stone Lake, just outside the city limits, added a phase in 2025 too.
When land is platted in Collinsville, the application has to show the planned water supply and sewage disposal. If a lot is not on city sewer, state rules set its minimum size. With public water, a spray system needs half an acre, and a slow-draining conventional field needs a full acre. With a private well, the spray minimum rises to three quarters of an acre.
Plan the system before the house plan is final, and keep fill dirt off the tested area. More than 6 inches of fill there can mean a new soil test. State setbacks keep tanks and lateral lines 15 feet from a stream, and spray heads 25 feet back. That matters on lots along Blackjack Creek and Horsepen Creek.
