La Mesa owns and runs its sewer collection system, and private sewer laterals are the property owner's to maintain. With a median home built around 1970, plenty of La Mesa houses still drain through original pipe that is prone to roots and cracks. Call the number on this page to be connected with a local plumber in La Mesa.

Symptoms that point past a single drain
- Dirty water rising in a shower pan or tub
- A toilet that bubbles when the bathroom sink empties
- Slowdowns in the kitchen and the bathrooms on the same day
- Water seeping from the cleanout cap in the yard
- A sewage smell outside near where the line leaves the house
If only one fixture is sluggish, the problem is probably close to that fixture. When several drains back up together, look at the line that carries everything out to the street.
La Mesa's sewer system and older homes
According to the city's Sewer System Management Plan, La Mesa operates about 165 miles of gravity sewer mains, and all of its flows go to the City of San Diego's Metropolitan Wastewater System for treatment. The plan separates the city-maintained portions of sewer laterals from private laterals, which owners maintain. If you aren't sure where that line falls at your address, ask the city before anyone digs near the street.
City-Stats census figures put La Mesa's median home at about 1970, one of the older housing stocks in East County. Laterals from that period are commonly clay or cast iron. Clay joints separate and let roots in, and cast iron rusts and scales until the inside of the pipe is rough enough to snag paper. Hillside and canyon lots, common in this part of the county, can also mean long or deep laterals with more ground to work through.
Price factors
- Depth and length of the section that has failed
- Whether the damage sits on the private portion or reaches a part the city maintains
- Concrete, mature trees or retaining walls over the line
- Lining the old pipe versus replacing it
- Any plumbing permit from the La Mesa Building Division for changes to the existing system
