In San Tan Valley, sewer line replacement means new pipe for the private line from your house to EPCOR's wastewater system, which took over the former Johnson Utilities network. Homes here are mostly post-2000, so the trigger is usually a sagging, separated or damaged section rather than old pipe wearing out. Call the number on this page to be connected with a local plumber in San Tan Valley.

The local setup
San Tan Valley was desert and farmland that filled in quickly with planned communities after 2000, and it became an incorporated town in 2025. Sewer service comes from EPCOR's San Tan Wastewater district, the former Johnson Utilities system, which runs the enclosed Copper Basin Water Reclamation Facility. Water is split by address: EPCOR serves much of the town, and the Town of Queen Creek provides water only to some areas. Even where Queen Creek supplies the water, EPCOR is the sewer provider. Its main in the street is EPCOR's to maintain; the pipe from your foundation out to it is the homeowner's, and that is the part a plumber replaces.
What to do now
- Cut back on water use the moment a drain backs up, so waste doesn't rise into the lowest tub or shower.
- Look at the outdoor cleanout. If it's full or overflowing, the blockage sits between the house and EPCOR's main.
- Call EPCOR for a public problem. If sewage is surfacing in the street or neighbors are affected, EPCOR Customer Care is 1-800-383-0834.
- Get the line cleared and filmed. A camera inspection shows whether a repair will hold or the line should be replaced.
- Ask about the permit path before work starts, since building services moved from the county to the new town.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Main-line clog returns after clearing | Belly or offset joint that traps solids |
| Standing water visible on camera | Pipe settled after the original backfill |
| Roots at a fitting | Joint opened up enough for roots to enter |
| Broken or flattened pipe | Damage from later digging, a pool or heavy loads above |
What affects the cost
- Length and depth of the run to EPCOR's connection
- Whether the pipe can be burst or lined, or has to be dug and regraded
- Driveways, pavers, turf and HOA landscaping over the route
- Interior drain work under the slab, if the camera finds problems there
- Permit and inspection: the Town of San Tan Valley now handles building processes, with Pinal County providing building safety, plan review, permitting and inspection services under intergovernmental agreements. Permits the County issued before the switch stay with the County until closed out.
