Fontana collects and bills sewer through the City of Fontana Sewer Service, and the Inland Empire Utilities Agency treats the wastewater. The pipe that runs from your home to the public sewer is the owner's to repair, which is a job for a plumber. Call the number on this page to be connected with a local plumber in Fontana.

What happens when you call
Your call goes to an independent plumber who works in Fontana. Expect a few quick questions: which fixtures are backing up, whether this has happened before, if you know where the cleanout is, and whether anything has been planted or built over the line. Most sewer visits start by clearing a path through the blockage so the house is usable again, then a camera goes down the line to show why it stopped. That footage is what a repair plan is based on, so ask to see it.
If a spot repair is all that is needed, the plumber explains where they would dig and how deep. If the camera shows broken or bellied pipe along much of the run, they will talk through lining or replacing it.
What affects the cost of a sewer repair
- Length and depth of the damaged section. A short break near the foundation costs less to reach than one far out under the street side of the yard.
- What is on top. Driveways, block walls and mature landscaping add restoration work.
- Pipe material and condition. Brittle older pipe may not survive a partial repair, which can push the job toward a longer section.
- Method. Excavation, lining and bursting each suit different damage.
- Permit and inspection. Fontana Building & Safety handles permits and inspections, online through Build Fontana or at the counter at 8353 Sierra Avenue.
Local conditions in Fontana
The City of Fontana Sewer Service, at 16860 Valencia Avenue, handles collection and billing, with treatment through the Inland Empire Utilities Agency. Chapter 23 of the Fontana Municipal Code requires buildings within 200 feet of a public sewer to connect to it at the owner's expense. Water is a different story: five water companies serve defined areas of Fontana, so the agency on your water bill may have nothing to do with your sewer.
Fontana's median year built is 1989 according to city-stats.com, so most laterals are not antique, but a large share have now been underground for well over 30 years. Older parts of the city can still have clay or cast iron lines, while newer tracts tend to have plastic pipe whose usual weak point is a joint that roots have found.
Before the plumber arrives
- Stop running water, including the dishwasher and washer
- Find the cleanout cap outside, often near the foundation, and clear around it
- Move cars or items off the driveway if the line may run under it
- Note when the problem started and which drains are affected
