Apache Junction businesses get water from either the Apache Junction Water District or Arizona Water Company, depending on location, and sewer from the Apache Junction Sewer District. The Water District requires backflow assemblies to be tested every year at the owner's expense. Call the number on this page to be connected with a local plumber in Apache Junction.

Local conditions in Apache Junction
Two water utilities serve the city, and the city's Water Resources page has a Find My Provider map to sort them out. The Apache Junction Water District blends groundwater from the Eastern Salt River sub-basin with CAP water filtered at the Superstition Area Water Plant, with a Mesa interconnect as backup. Arizona Water Company relies mainly on wells, with CAP contracts. The Water District classifies its blended water as hard, above 10.5 grains per gallon, which is enough to coat heater tanks and food-service equipment over time. Sewer is a third agency, the Apache Junction Sewer District (480-941-6754).
Permits come from Development Services Building Safety and Inspection at 300 E. Superstition Boulevard (480-982-8002), applied for through MyGovernmentOnline. The city's plumbing permit covers repipes, repairs, traps and water heater changes, and work that replaces or rearranges valves, pipes or fixtures needs one. The Water District keeps a lead service line inventory on its website and reports a very low risk of lead in its lines. Southwest Gas is the natural gas utility; if anyone smells gas, get everyone out, then call 911 and Southwest Gas at 877-860-6020 from outside.

Warning signs
- A test notice from the Water District with the deadline approaching

- Water heaters that rumble, leak or fall short on hot water
- Restroom fixtures that run or stick
- Pooling water near the meter or the backflow assembly
Timing notes
Nearby draws such as the Superstition Mountains, Goldfield Ghost Town and Canyon Lake can mean busy stretches for restaurants and shops, so it pays to schedule drain cleaning, heater flushing and backflow testing before peak weeks. The Water District can terminate water service if a required test is skipped, so leave time for a repair and retest if a device fails. Summer heat is hard on irrigation and backflow parts, and the occasional winter freeze can crack an exposed assembly.
