Surprise is a West Valley city where water and sewer can come from the City of Surprise, EPCOR or, in the Original Town Site, the City of El Mirage, so the first step on many jobs is knowing your provider. Plumber Phoenix is a free referral line that links callers with independent plumbers. Call the number on this page to be connected with a local plumber in Surprise.

A large, young city in the northwest Valley
Surprise is in Maricopa County in the northwest part of the metro, about 22 miles in a straight line from downtown Phoenix. The 2020 Census counted 143,152 people. Its closest neighbors include El Mirage, Youngtown and the Sun City communities, and most of its growth is recent. Census survey figures put the median year built at 2004, and only about 3 percent of housing units predate 1980.
Three possible water providers
Surprise provides water, sewer and trash service, but the city itself says not all residents and businesses are on its system. EPCOR, a private regulated utility, provides water and/or wastewater service to certain Surprise neighborhoods, and the City of El Mirage Water Services Division serves the Original Town Site of Surprise. The City of Surprise offers a "Find your Drinking Water Provider" lookup at surpriseaz.gov/my-surprise-address, and your water bill will also show who serves you.
That matters when something goes wrong. A main break in the street, a meter problem or a water quality question goes to whichever utility serves the address, and each utility sets its own rules for things like backflow testing. The city posts its drinking water quality reports at surpriseaz.gov/drinking-water-quality-reports; if you are an EPCOR or El Mirage customer, look to that utility's report instead.
For sewer, the City of Surprise owns and operates most of the wastewater system inside city limits, with EPCOR serving some residents.
Permits and gas safety
Plumbing permits and inspections are handled by the City of Surprise Community Development Department through its Permits and Inspections division. Ask a plumber or the department whether a specific job, such as a water heater change or new gas piping, needs a permit.
We could not confirm the gas utility for Surprise addresses, and many newer Valley homes are all-electric. If you ever smell gas, leave the house first, then call 911 and your gas utility from outside. If your home uses propane, call 911 and your propane supplier.
What plumbing work looks like here
With most homes built in the 2000s or later, Surprise calls tend to involve original water heaters reaching the end of their life, PEX or copper fittings, pressure regulators, irrigation leaks, garbage disposals and drain clogs rather than old galvanized supply lines. Slab-on-grade foundations are standard, so a hidden leak can show up as a warm spot on the floor or a jump in the water bill.
Compared with Phoenix, the biggest difference is the patchwork of providers. Inside Phoenix one city department handles water and sewer; in Surprise you may be dealing with the city, EPCOR or El Mirage. When you call, mention your provider if you know it and whether the water is shut off, and you will be connected with an independent plumber who works in Surprise and sets the price with you.
