Steps
Determine which county health/environmental department has jurisdiction, since Arizona regulates potable water haulers primarily through county code rather than a single statewide ADEQ hauler license
In Maricopa County, comply with Chapter V Section 2 of the Environmental Health Code and Arizona Administrative Code Title 18, Chapter 4, Section 125 to obtain a potable water transportation operating permit from the county Environmental Services/Solid Waste program
In other counties (e.g., Coconino, La Paz), submit the county's water hauler/waste hauler license application covering vehicle, tank, and sanitation requirements
Check azdeq.gov's 'Permits Needed for a Water Company/Utility' page for any state-level drinking water facility approvals that also apply if you operate as a consecutive/wholesale system
Renew the county permit annually and keep vehicle inspection and tank sanitation records on hand for inspection
Known gotchas
Arizona's ADEQ septage hauler license (750+ gallon capacity) is a completely separate program from potable water hauling — do not confuse the two when researching 'water hauler license Arizona'
Because potable-water-hauling authority sits with counties, a permit issued in one Arizona county does not automatically transfer if you expand service into a neighboring county
ADEQ's own site does not list a standalone statewide 'bulk water hauler' permit page as of mid-2026 — always confirm with the specific county office rather than assuming a state form exists
