Backflow in Maricopa
The City of Maricopa doesn't run a water utility. Global Water's Santa Cruz Water Company serves most of the city with groundwater, and Global Water runs a Backflow and Cross Connection Control Program that requires backflow prevention assemblies to be installed and tested periodically. Some older parts of Maricopa are on the Maricopa Domestic Water Improvement District instead, which says it doesn't serve subdivisions; its backflow rules weren't found in the research behind this page. Global Water's Palo Verde Utilities also distributes recycled water in the city, which makes keeping reclaimed and drinking water lines apart especially important.
What to do now
- Confirm your provider on your bill: Global Water or the Domestic Water Improvement District.
- Stop active leaks by closing the irrigation valve or main. Don't plug a vent or relief port.
- Ask Global Water how often your assembly must be tested and how results are filed.
- Book a certified tester through the number on this page.
- Check permits for new or relocated devices with Development Services, Building Safety, at (520) 316-6920; submittals go through the city's VIP Portal.
Signs and their usual causes
| Symptom | Likely cause |
|---|---|
| Relief port dripping on a reduced pressure assembly | Scale or debris on the first check |
| Vent cap leaking at zone start | Worn seal on a vacuum breaker |
| Brittle or cracked cap | Years of sun exposure |
| Reclaimed water line near a house hose bibb | A possible cross-connection to correct |
| Failed test with no visible leak | Check valve not seating |
Global Water reports hardness averaging about 215 ppm as calcium carbonate in the Maricopa system. With a median year built around 2007 and roughly 63% of homes built from 2000 to 2009, a lot of devices along John Wayne Parkway and Smith-Enke Road are at the age when original parts wear out together.
Cost factors
- Pass, or rebuild and retest
- Device type and size
- Replacement for cracked or discontinued units
- Permits for new or moved assemblies
- Number of devices on HOA or commercial sites
- Correcting a reclaimed water cross-connection if one is found
Ask up front whether filing the result with Global Water is part of the job.
