San Tan Valley homes get water from EPCOR across much of the town or from the Town of Queen Creek in some areas, and a leak on the buried pipe between the meter and the house is generally the owner's repair. Watch for wet ground, weak pressure and a bigger bill. Call the number on this page to be connected with a local plumber in San Tan Valley.
The local setup
San Tan Valley grew quickly after 2000 from desert and farmland into planned communities such as Johnson Ranch, Pecan Creek South, San Tan Heights and Archer Meadows, and it became an incorporated town in 2025. Water service varies by address. EPCOR, which took over the former Johnson Utilities systems, provides both water and wastewater across much of the area, while the Town of Queen Creek provides water only to some San Tan Valley neighborhoods. EPCOR's customer care number is 1-800-383-0834.
What to do now
- If water is spraying or pooling fast, close the main shutoff at the house.
- Turn off irrigation, the pool fill and anything else that draws water.
- Look at the meter. Movement with everything off confirms a leak past the meter.
- Check your bill to see whether EPCOR or Queen Creek serves you, and call them if water is surfacing at the meter box.
- For a leak between the meter and the house, call a plumber to pinpoint it before digging.
What the symptoms point to
| Symptom | Likely cause |
|---|---|
| Wet strip across the front yard | Leak in the private service line |
| Water collecting in the meter box | Meter or utility-side connection |
| Weak pressure at every tap | Damaged service line or a pressure regulator problem |
| Meter moving, yard dry | Leak inside the home or under the slab |
| Puddles near a drip emitter | Irrigation line, not the house supply |
Cost factors
- Cause of the leak. In neighborhoods built mostly after 2000, a single failed fitting or a line cut during yard work is common and simpler to fix than a failing pipe.
- Route and surfaces. Pavers, block walls, turf and gravel along the path add restoration time.
- Distance. A longer run from the meter means more digging.
- Repair or full replacement. One section versus the whole line.
- Permitting. The Town handles zoning and building within its limits, with Pinal County providing building safety, plan review, permitting and inspections under agreements; the plumber can confirm what your job needs.
EPCOR keeps a service line material inventory at epcor.com/safety and says it is responsible for removing any lead pipes it identifies. EPCOR's San Tan water is groundwater at 15 to 18 grains per gallon, hard on fixtures but rarely the reason a buried line fails.
