What PORA, the county and EPCOR each do
Sun City West is an unincorporated part of Maricopa County. The Property Owners and Residents Association (PORA) puts it plainly: “there is no city government, mayor or staff.” PORA, active since 1979, describes itself as the quasi-governmental group that works with the county. When water is the problem, here is where things go:
- EPCOR provides water and sewer service. Leaks in the street or at the meter are the utility’s.
- You handle leaks past the meter. The Smart Home Water Guide from the City of Phoenix and the Arizona Municipal Water Users Association puts finding and fixing leaks on the homeowner’s side of the meter box on the homeowner.
- The Flood Control District of Maricopa County handles floodplain management for unincorporated areas like Sun City West.
- The Arizona Fire and Medical Authority covers fire and medical emergencies.
A 1980s and 1990s housing stock
U.S. Census Bureau survey data (American Community Survey, 2020–2024) puts the median Sun City West home at 1989, and most homes date from the 1980s and 1990s. About 88% are owner-occupied, about 81% are detached houses and about 11% are attached. Each household must include at least one person 55 or older.
The parts worth a look in a home this age:
- AC drain pans and lines. The Department of Energy’s Building America program notes that older galvanized steel drain pans can corrode, and that clogged drains and overflowing pans in attics and closets can go unnoticed long enough to cause severe damage. The guide on AC water leaking through the ceiling covers the signs.
- Pipes under the slab. The Smart Home Water Guide suggests checking for warm spots on the floor after running hot water nearby, which could mean a leaking hot water pipe under the concrete. See slab leak water damage.
- The current water heater. Check the date on its label. ENERGY STAR puts the typical tank life at about 13 years.
Coming back to a wet house
About 9% of Sun City West homes, roughly 1,700, are vacant for seasonal or occasional use, according to the same Census data. In an empty house, nobody is there to notice a leak. The City of Phoenix suggests shutting off the water to the house before a long time away, so a failed line can’t run for months.
If you return to water on the floor, a musty smell or stained drywall:
- Close the main valve and stay clear of water near outlets or cords.
- Take photos and video before cleaning up.
- Call your insurer and keep notes on dates and names.
- Hold off on fans until mold is ruled out. The joint EPA and CDC guide warns that fans can spread mold that has already started to grow.
See signs of hidden mold and mold remediation.
Hardness from 3 to 11 grains
EPCOR serves about 15,600 connections in Sun City West with groundwater from the West Salt River Valley. Its 2025 water quality report puts hardness at 3 to 11 grains per gallon, from “moderately hard” to “very hard” on EPCOR’s scale.
Hard water leaves sediment in tank water heaters. The City of Scottsdale’s water heater guide suggests draining at least 5 gallons every six months where water is high in minerals, and notes that a water softener can wear out the tank’s anode rod faster. See water heater and appliance leaks.
The 2019 and 2020 sewer repairs
EPCOR runs the Sun City West wastewater system. It reports repairing or refurbishing 95 manholes in 2019, and repairing and rehabilitating 8,722 feet of gravity main, more than 1.6 miles, across 2019 and 2020. The line from a home to the main is a separate matter, so ask EPCOR where its part ends if you have a backup. Many homeowners policies need an added endorsement to cover sewer backups. If sewage comes up a drain, see sewage backup cleanup.
Heavy rain and a funnel cloud
On August 19, 2014, a trained spotter about two miles north-northeast of Sun City West estimated more than an inch of rain in an hour. During the November 18–19, 2025 storms, a funnel cloud was seen from Sun City West. After storms like these, check ceilings for new stains.
If you find water
- Close the fixture valve or the main shut-off, turning it by hand.
- Keep away from standing water near electrical outlets.
- Photograph the damage.
- Call to reach an independent restoration provider that serves Sun City West, and a plumber for the repair.
