City of Mesa Water Resources provides both water and wastewater service, so the mains under Mesa streets belong to the city. When the pipe carrying waste out of your house cracks, separates or fills with roots, that repair is plumbing work. Call the number on this page to be connected with a local plumber in Mesa.

Clues that point to the main line
- A toilet gurgles when the washing machine empties
- Dirty water rises in the tub or shower, usually the lowest drains in a single-story slab home
- Two or more bathrooms slow down on the same day
- The outdoor cleanout cap is wet or has waste around it
- A clog returns within weeks of being cleared
One sluggish bathroom sink is normally a trap or branch clog. When fixtures in different rooms act up together, the shared line running under the slab and out through the yard is the likely culprit.
Mesa's sewer system and housing
The City of Mesa handles wastewater collection across the city and asks residents to report sewer overflows and backups to its water emergency line, 480-644-2262. If sewage is coming out of a manhole or running in the street, call the city first. If the street main is flowing and only your house is affected, the trouble is almost always in the building sewer.
Mesa is the most populous city in the East Valley, with a historic downtown along Main Street and decades of growth spreading east and south from it. Census figures put the median home in Mesa at about 1988. Houses from that period and earlier can still have cast iron or clay drain lines, which crack, scale up inside and let roots in at the joints. Plastic lines in newer neighborhoods hold up better but can sag where backfill settled or get cut by later pool, patio or irrigation work.
What shapes the price
- Depth of the line and the length of the damaged run
- What sits on top: grass, gravel, pavers, a driveway or a pool deck
- Whether a spot repair, a liner or a new section of pipe fits the damage
- Whether there's a usable cleanout or one has to be added
- Permit and inspection through City of Mesa Development Services, Permit Services
Once you're connected
Your call goes to an independent local plumber who works in Mesa. Mention roughly when the house was built, which fixtures are backing up and whether anyone has cleared the line before. Hold off on laundry and long showers until the visit. The usual sequence is to open the line, run a camera to see the break, roots or sag and mark how deep it is, and only then talk through repair choices.
