Water and sewer in Surprise can come from the city, EPCOR or the City of El Mirage depending on the address, but the first step is the same everywhere: close the main valve. If you smell gas, get outside and call 911 and your gas utility, then call the number on this page to be connected with a local plumber in Surprise.

Three possible water providers
The City of Surprise supplies water, sewer and trash service to much of the city, but it says not every resident is a city customer. 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. The city's "Find your Drinking Water Provider" lookup at surpriseaz.gov/my-surprise-address shows which one serves an address, and your water bill names it too. On the sewer side, Surprise owns and operates most of the wastewater system inside city limits.
Housing here is young: the median year built is 2004, and only about 3 percent of homes date from before 1980. Emergencies tend to involve water heaters, fixture supply lines, irrigation connections and slab leaks rather than worn-out old pipe. We did not find an official page naming the gas utility for Surprise, so check your bill and keep that number handy.
Who handles it
| Problem | Who to call |
|---|---|
| A main break in the street or water from the meter box | Your water provider: the city, EPCOR or El Mirage |
| Sewage overflowing from a manhole | The sewer provider named on your bill |
| A pipe or water heater leaking inside | A plumber, once the main is closed |
| A backup in one home only | A plumber to clear the private line |
| Gas odor | Leave, then 911 and your gas utility |
Signs you need help tonight
- Water on the floor that keeps coming back after you mop
- Toilets bubbling when the washer drains
- The meter showing use with every fixture turned off
- A leak at the water heater's tank or its fittings
Seasonal timing
Summer is hard on water heaters in hot garages and on drip and irrigation lines, and monsoon storms can push debris into yard drains and cleanouts. Hard freezes are uncommon in the West Valley, but an exposed hose bib or backflow assembly can still split on a cold night. Permits for any follow-up work go through the City of Surprise Community Development Department. Expect a higher charge for nights and weekends, and note that no arrival time is promised.
