An educational, cited reference for homeowners — not a claim that ClickSeptic services Arkansas today. ClickSeptic has zero live markets anywhere yet.
Short answer: Onsite (septic) wastewater systems in Arkansas are regulated statewide under the Arkansas Sewage Disposal Systems Act (Act 402 of 1977, as amended, codified at Ark. Code Ann. § 14-236-101 et seq.), administered by the Arkansas Department of Health (ADH). ADH's Onsite Wastewater program sets statewide policy and rules (most recently the 'Rules Pertaining to Onsite Wastewater Systems,' effective September 5, 2024) and works through Environmental Health Specialists in each county health unit, who handle local permit review, site evaluations, and inspections. Systems above certain size thresholds (5,000 gpd for subsurface disposal, 2,000 gpd for surface-discharging designs) or those with a surface discharge also fall under the jurisdiction of the Arkansas Department of Energy and Environment / ADEQ for discharge permitting, creating a dual state-agency structure for larger or discharging systems while ADH retains primary authority over typical residential septic systems.

Onsite (septic) wastewater systems in Arkansas are regulated statewide under the Arkansas Sewage Disposal Systems Act (Act 402 of 1977, as amended, codified at Ark.

ADH's Onsite Wastewater program sets statewide policy and rules (most recently the 'Rules Pertaining to Onsite Wastewater Systems,' effective September 5, 2024) and works through Environmental Health Specialists in each county health unit, who handle local permit review, site evaluations, and inspections.

No statewide law or ADH rule was found requiring a septic system inspection to be performed as a condition of selling or transferring residential property in Arkansas. The ADH Onsite Wastewater FAQ page addresses how to locate an existing permit record, how to obtain a new permit, and licensee/installer search tools, but does not describe a point-of-sale inspection mandate. Any inspection at the time of a home sale in Arkansas would be a matter of private contract between buyer and seller (or a lender requirement) rather than a statutory obligation.
No fixed statewide pump-out interval (e.g., 'every X years') is codified in Arkansas's Rules Pertaining to Onsite Wastewater Systems as published by ADH. The rules focus on system design, siting, soil evaluation, tank specifications, and installer/monitoring-program requirements (particularly for alternative and monitored systems) rather than mandating a specific homeowner maintenance schedule for pumping. Systems under an Operation and Maintenance Program (OMP) — required for certain alternative technologies — do have periodic monitoring and servicing built into their permit conditions, but this is technology-specific rather than a universal pump-out law applicable to all conventional septic tanks.
An onsite wastewater permit is required before installation, issued through the county health unit in cooperation with a licensed 'Designated Representative' (a state-licensed engineer, land surveyor, sanitarian, or master plumber, or an individual otherwise qualified in soil science) who performs the soil evaluation and system design. Arkansas has no statewide minimum lot size for septic systems; suitability instead depends on soil conditions, the number of bedrooms, and a mandatory 100-foot setback from water wells. Installation must be performed by an ADH-licensed Onsite Wastewater System Installer, and separate licensing tracks exist for septic tank cleaners/pumpers and septic tank manufacturers, all administered by ADH's Onsite Wastewater program under Act 402 and its implementing rules.
Arkansas updated its statewide Rules Pertaining to Onsite Wastewater Systems effective September 5, 2024, and the program notably has no statewide minimum lot size requirement for septic-served properties — suitability is judged purely on soil conditions, bedroom count, and well setback distance (100 feet), giving Arkansas one of the more soil-driven, less prescriptive lot-size regimes among the states surveyed.
