Colton’s history as one of the oldest cities in the Inland Empire is visible in its neighborhoods — charming homes, established streets, big shade trees. But beneath those streets and yards, that history also means some of the oldest residential sewer lines still in service in San Bernardino County.
If your Colton home was built before the mid-1980s, there’s a strong chance the sewer lateral connecting your house to the city main has never been replaced. And after 40 to 80 years of service, these pipes are failing at an increasing rate.
What’s Happening to Colton’s Sewer Lines
Material degradation. Homes from the 1940s through 1960s commonly have vitrified clay tile sewer lines. These were the standard at the time and performed well for decades — but clay is brittle, and joints sealed with mortar weaken and separate over time. Homes from the 1960s and 1970s may have Orangeburg pipe (compressed tar paper), which has an even shorter lifespan and tends to collapse under soil pressure after 30 to 40 years.
Root intrusion. Colton is full of mature trees — cottonwoods, sycamores, pepper trees, and ornamental figs — with aggressive root systems that seek out moisture. Once roots find a weakened joint in a clay sewer pipe, they enter and grow rapidly. The blockages they create get worse every month. Our post on common causes of sewer line blockages covers this and other contributing factors.
Ground settling. The alluvial soils in the Colton area compact and shift over decades, causing sewer pipes to develop bellies — low spots where waste and water pool instead of flowing downhill to the main. Bellies cause chronic slow drainage and can only be corrected by replacing the affected section of pipe.
How to Diagnose the Problem
The smart first step for any sewer problem in Colton is a sewer camera inspection. The camera shows exactly what’s inside the pipe — roots, cracks, collapse, grease buildup, offset joints, or bellies — and pinpoints the precise location of each issue. This eliminates guesswork and ensures that the repair addresses the actual problem. We covered the full value of camera inspections for Colton homes in our post on sewer camera inspection in Colton.
Repair Options for Colton Homeowners
Rooter clearing + hydro jetting. If the camera shows root intrusion in an otherwise intact pipe, clearing the roots with a rooter service followed by hydro jetting to clean the pipe walls can restore full function. This buys time — typically 12 to 18 months before roots regrow — and is appropriate when the pipe itself is structurally sound.
Spot repair. When a specific section of pipe is cracked, collapsed, or has a severe offset joint, that section can be excavated and replaced while leaving the rest of the line intact. This is the most common repair for localized damage in an otherwise functional sewer lateral.
Full line replacement. When the camera reveals damage throughout the line — widespread cracking, multiple bellies, or Orangeburg pipe that’s collapsing — full sewer line replacement is the right call. New PVC sewer pipe has a 100+ year expected lifespan and is resistant to root intrusion, corrosion, and ground movement. It’s a one-time investment that eliminates recurring sewer problems permanently.
Trenchless options. In some cases, pipe lining (CIPP) allows a new pipe to be installed inside the existing one without excavation. This works well when the old pipe’s path is intact but the material has deteriorated. Not every situation is a candidate for trenchless — the camera inspection determines feasibility.
Don’t Wait for a Full Backup
A sewer line that’s showing early warning signs — slow drains, gurgling, occasional odors — is a pipe that’s going to fail completely at some point. Addressing it on your schedule with a planned repair is always less expensive and less disruptive than dealing with a sewage backup emergency.
The California Plumbing Code governs sewer line standards statewide, and all repairs must meet current code regardless of what was originally installed. A licensed plumber ensures the work is done right and passes inspection.
