Replacing a sewer line means installing new pipe for the run between the house and the public sewer, either by digging a trench or by a trenchless method such as pipe bursting. It makes sense when the line is collapsed, badly bellied or damaged along much of its length. Call the number on this page to be connected with a local plumber in Riverside.

When replacement beats repair
A single cracked joint is a repair. A camera video showing roots at joint after joint, pipe walls flaking away, or a long low section full of standing water is a different story. Patching one spot on a line in that shape often just moves the next failure a few feet down. Homes in older Riverside districts can still have original clay or cast iron laterals, and the city's median home dates to about 1976, so many lines are reaching the point where an owner weighs replacement.
Ways the work is done
- Open trench: the old pipe is dug out and new pipe laid to proper slope. It allows a sag to be corrected and works for nearly any line, at the cost of disturbing the yard, driveway or patio above it.
- Pipe bursting: a bursting head pulls new pipe through the path of the old one while breaking the old pipe outward. It needs small access pits rather than a full trench.
- Lining: a resin liner forms a new pipe inside the old one. It works only where the existing pipe still has its shape and slope.
A plumber picks among these based on depth, pipe condition, slope, and what is built over the line.
Permits and the City system
Sewer replacement is the kind of job that commonly calls for a plumbing permit and inspection. In Riverside, plumbing permits come from the City's Building & Safety Division, which has a Permit Counter at (951) 826-5800 and an online permit portal. The City's Public Works department runs the wastewater system for most addresses, and Western Municipal Water District serves a small portion of the city. Ask the plumber who pulls the permit and how the connection to the public sewer is handled.
What drives the total
- Length and depth of the line
- Method, and whether trenchless is possible
- Concrete, pavers or mature landscaping over the route
- Cleanout installation if the home lacks one
- Permit and inspection requirements
Ask for the camera video, the proposed method and a written scope so quotes can be compared on the same work.
Before digging
Buried utility lines need to be marked before excavation. Calling 811 in advance is the standard first step for any digging on a property.
