Arizona Septic Hauling Compliance Guide

Septic haulers working under the Arizona sun face a regulatory framework centered on the Arizona Department of Environmental Quality (ADEQ) and its governing rule, A.A.C. R18-13-1103. Unlike many states that license haulers at the business or individual level, Arizona requires registration on a per-vehicle basis. Each pump truck operating in the state must carry its own active registration with ADEQ, with an initial fee of $250 and annual renewals at $75. Those registrations are non-transferable, meaning you cannot simply move a permit from one vehicle to another if you swap out trucks.

Every trip requires a manifest documenting the generator name, generator address, waste type, total gallons, vehicle ID, and disposal site. Arizona also sets a minimum tank size of 750 gallons for pump trucks, so smaller utility vehicles will not qualify.

On the grease trap side, Arizona's liquid waste program is broader than many operators assume. ADEQ treats grease-interceptor and oil-water-separator wastes within the regulated liquid waste stream. That means you stay inside the same ADEQ registration framework, even though local pretreatment and receiving-facility requirements still matter. Land application of grease trap waste is not allowed.
