The Short Answer

The Arkansas Department of Health regulates septic systems statewide. Through its Onsite Wastewater program, ADH permits and oversees septic tanks, drain fields, and other onsite wastewater systems — not Benton County, not Washington County, and not your city building department.

That matters in Northwest Arkansas because a lot of new homes in Centerton, Gravette, Bella Vista, and the rural edges of Bentonville and Springdale are still outside city sewer. If you're building or replacing a system, the permit path is state health, not a county septic office.

What ADH Actually Controls

Routine pump-outs and many small repairs (baffles, lids, effluent filters) usually don't need a brand-new system permit. Installing a system, replacing one, or rebuilding a failed drain field generally does.

Why People Assume the County Handles It

In some states, counties run onsite wastewater permitting. Arkansas doesn't work that way for septic. Homeowners often call the county first, get pointed elsewhere, and lose a week. Builders sometimes treat septic as a last-mile surprise on a new lot that never had city sewer planned.

If you're buying a home on septic, or building outside municipal sewer in Rogers and surrounding NWA, ask early: who pulls the ADH Onsite Wastewater permit, and is the system already permitted as built?

Arkansas Septic Rules — Common Questions

Who regulates septic systems in Arkansas?

The Arkansas Department of Health Onsite Wastewater program — not the county.

Do I need a permit for a new septic system?

Yes. New systems and full replacements go through ADH. On new construction, a permitted system is typically required before you can get a certificate of occupancy. See our installation page for what's involved.

Does a real estate septic inspection replace an ADH permit?

No. A septic inspection for a home sale is a condition report. It doesn't create or transfer a construction permit. Permitting is a separate ADH process when a system is installed or significantly modified.

Can you handle the ADH paperwork?

Yes. For installs and major repairs we handle, we work the ADH Onsite Wastewater permit process as part of the job so you're not stuck translating state forms on your own.
