Peoria runs its own Water Services Department and its own water reclamation plants, and the city says a homeowner replacing a water heater needs a permit from its Development and Engineering Department. Required backflow assemblies are tested every year by a City of Peoria Recognized Tester.

Plumbing services in Peoria
A long city in the northwest Valley
Peoria is a Maricopa County city about 13 miles northwest of downtown Phoenix in a straight line. It runs a long way north, from Old Town Peoria along Grand Avenue up toward Lake Pleasant Regional Park, with newer master-planned neighborhoods such as Vistancia along the Loop 303 corridor. The Peoria Sports Complex hosts spring training for the Padres and Mariners. Peoria incorporated in 1954, and the 2020 Census put its population at 190,985.
City water and city reclamation plants
Drinking water comes from the City of Peoria Water Services Department, and Customer Service and Utility Billing answers at (623) 773-7160, 7 a.m. to 6 p.m.. Wastewater is handled by the city as well. The Beardsley Water Reclamation Facility serves the northwest part of Peoria, the Jomax facility serves Vistancia, and the Butler facility processes biosolids from Beardsley. For hardness and other water quality details, check the city's current water quality report rather than relying on a neighbor's softener setting.
Backflow rules are strict here
Peoria's Environmental Division, part of Water Services, runs the backflow prevention program. Every required assembly must be tested at least once a year, or more often if the manufacturer or the Division calls for it, and the owner pays for the test. The city mails a notice 60 days before a test is due, the tester has to be on the City of Peoria Recognized Tester list, and the report must reach the Environmental Division within 30 days. Skipping a test can lead to water service being shut off. New assemblies must be inspected by the Environmental or Building Safety Division. The Cross Connection Specialist is at (623) 773-8444.
Permits, including water heaters
Plan review and building permits come from the Development and Engineering Department. Unlike some neighboring jurisdictions, Peoria states plainly that a homeowner replacing a water heater must have the job permitted. Residential gas line permits and miscellaneous minor plumbing permits are reviewed over the counter, and inspections are scheduled at 623-773-8445.
Housing and gas
The median Peoria home was built in 1998, so most houses are on the newer side, with an older core around Old Town. Expect the usual Valley work: water heaters, slab leaks, scale on fixtures and irrigation tie-ins. We could not confirm the gas utility for Peoria on an official page; your gas bill names it. If you smell gas, leave the house first and then call 911 and your gas utility from outside.
How Peoria differs from Phoenix
A Phoenix homeowner deals with City of Phoenix Water Services and Phoenix permits. In Peoria, a different city handles both, with its own tester list, its own 30-day reporting rule and a clear permit requirement for water heaters. When you call the number on this page, mention the part of Peoria you are in and what is going on, and you will be connected with an independent plumber who works the area and quotes the job with you.
