Fontana sewer collection is a City of Fontana service, with treatment by the Inland Empire Utilities Agency, so a clog anywhere on your property is private plumbing to clear. Water service varies by address, but that does not change who handles the drains. 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 takes drain work in Fontana. Expect a few questions: which fixtures are slow, whether water has come up in a tub or shower, and whether the house has an outside cleanout. That tells the plumber whether to bring hand tools for a single fixture or a larger machine for the main line. Ask how the visit is priced before work starts. No arrival time is promised; it depends on the plumber's schedule.
On site, the plumber usually runs water to see where it backs up, opens the nearest access point and clears the line with a cable or a jetter. If the line clogs again soon, a camera inspection can show why.
What affects the cost
- Depth of the clog. A bathroom trap takes minutes; a main line plugged far out toward the street takes longer.
- Access. A cleanout outside the house is faster than going through a roof vent or pulling a toilet.
- What is in the pipe. Grease, wipes and roots each need different tools.
- Camera work. Recording the line adds to the bill but can prevent paying twice for the same clog.
- Hour of the call. Nights and weekends generally cost more.
Local conditions in Fontana
The City of Fontana bills and runs sewer service from 16860 Valencia Avenue, (909) 350-7670, and wastewater treatment is handled by the Inland Empire Utilities Agency. Fontana Municipal Code Chapter 23 requires buildings within 200 feet of a public sewer to connect at the owner's expense, which tells you how the City sees the line from the house: it is the owner's pipe.
Water is a different story. Five companies serve defined areas of Fontana, with Fontana Water Company the main provider, so the name on your water bill varies by neighborhood. For drain work it matters only if a plumber needs to shut off water; Fontana Water Company asks customers to use their own gate valve rather than the angle stop or meter valve, which belong to the company.
The median Fontana home was built in 1989. Many houses have plastic drain lines that clog mainly from grease, wipes and hair, while older streets can have older pipe where roots and scale are part of the picture.
Before the plumber arrives
- Stop running the washer and dishwasher.
- Find the cleanout cap, often near the foundation, and clear a path to it.
- Move stored items out from under the affected sink.
- Note when the problem started and anything recently flushed.
- Keep children and pets away from any standing wastewater.
