In San Bernardino, the city maintains the sewer main in the street and each property owner maintains the sewer lateral that runs from the house out to it. When that lateral cracks, sags or fills with roots, the fix falls to the owner and a plumber. Call the number on this page to be connected with a local plumber in San Bernardino.

Warning signs of a failing lateral
- Toilets gurgle when the washing machine drains
- The lowest tub or shower in the house backs up first
- Several drains slow down in the same week
- A snaked line clogs again within a month or two
- Sewage smell near the cleanout or along the path to the street
One slow bathroom sink is usually a local clog. Trouble that hits several fixtures together points to the shared pipe leaving the house.
Sewer service and older pipe in San Bernardino
The San Bernardino Municipal Water Department runs wastewater collection and treatment for the city, and it also treats sewage for Loma Linda and Colton. Its FAQ is plain about the split: the city owns and maintains the main in the street, and the property owner maintains the sewer lateral. Properties within 200 feet of a sewer main are required to connect to it.
Age is the bigger local factor. In ZIP 92404, city-data.com counts roughly 72% of houses as built in 1979 or earlier. Laterals that old were often laid in clay or cast iron, and decades of root growth, shifting soil and earthquake shaking can open joints or crack a pipe wall. Homes in older parts of town such as the West Side and around downtown are where a camera most often finds offset joints and root masses.
What shapes the cost
- Where the damage sits. A break near the house is shorter and shallower to reach than one close to the street.
- Depth and surface. Digging through lawn is simpler than cutting a driveway or patio.
- Repair method. A single spot repair, a lined section and a full new lateral are very different jobs.
- Permit. The City of San Bernardino Building & Safety Division requires permits for plumbing work; plumbing-only jobs use its Mechanical, Electrical, or Plumbing Permit Application.
