When to call which utility
Use this Arizona utility map before a job changes a meter, service mast, service drop, gas appliance, water line, trench, driveway, sewer lateral, or exterior structure. For electric outages, meter pulls, temporary power, service upgrades, underground-to-overhead changes, or a panel job that requires a utility disconnect, start with the electric utility assigned to the address: Arizona Public Service, Salt River Project and Sulphur Springs Valley Electric Cooperative. Rural addresses often sit in cooperative territory even when the nearest city is served by an investor-owned or municipal utility, so verify the premise before an electrician schedules the cutover. For natural-gas odors, hit lines, meter relocations, pressure questions, or appliance conversions, stop work and call the gas utility or 911 from a safe distance when there is an immediate leak; use Southwest Gas for the listed gas distribution territory. Water utilities such as Tucson Water coordinate taps, meters, backflow requirements, main shutoffs, hydrant use, and service-line ownership questions. Municipal utilities may bundle electric, gas, water, wastewater, and stormwater, so one counter can control several approvals. Before any excavation, boring, fence post, sign, tree planting, drainage, sewer, or water-service work, file the 811 ticket through https://www.arizona811.com/ and wait for marks or positive response. The utility marks public facilities; the contractor still needs private locating for owner-installed lighting, irrigation, propane, septic, yard drains, and lines beyond the meter.
811 comes before utility-side work
File a locate request before trenching, boring, planting, fencing, drainage work, sewer work, or water-service changes. Utility marks do not replace private locating on owner-installed lines.
