Colton runs its own wastewater department, and City crews respond to blockages in the public sewer, but the line from your fixtures to the City main is yours to clear. Call the number on this page to be connected with a local plumber in Colton.
Colton, the "Hub City" known for the Colton Crossing rail junction, operates its own sewer system: more than 100 miles of collection pipeline and a City-owned treatment plant. City water and wastewater crews respond to sewer blockages in the public system, and the after-hours line is 909-370-5000. A clog inside your house or in the lateral running to the street is private. About half of Colton's homes were built before 1980 (median year built 1979), so older drain materials are common.
What to do now
- Stop running water. Every flush or load of laundry adds to the backup.
- See how far it reaches. One fixture means a local clog; several, or the lowest drain overflowing, means the main line.
- Check with a neighbor. If they are backing up too, call the City at 909-370-5000 after hours.
- Avoid chemical openers. They are hard on older pipe and seldom reach a main line clog.
- Find the cleanout. Do not open it if the line is full of water.
- Clear access. Move items from under sinks and away from the cleanout.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Bathtub drains slowly, nothing else does | Hair and soap at the drain or trap |
| Kitchen sink backs up after big meals | Grease coating the kitchen line |
| Shower fills when a toilet is flushed | Main line or lateral blockage |
| Main line clogs every few months | Roots or a damaged section in an older lateral |
| Scale ring inside old metal drain pipe | Hard water buildup narrowing the line |
Colton's water is hard: the City's 2025 report lists total hardness averaging about 207 mg/L for its Colton and Rialto sources. Scale does not cause most clogs, but it gives grease and soap a rough surface to build on in older pipe.
Cost factors
- How deep in the system the clog is
- Whether there is a usable cleanout
- Whether roots or grease need jetting rather than cabling
- A camera inspection for repeat clogs
- Night and weekend timing
If the fix involves replacing sewer pipe, the City of Colton requires a building permit for replacing water or sewer lines. Ask the plumber to confirm that before any digging starts, and ask for a copy of the camera recording if one is made.
