Sewer Line Repair in San Diego, CA

What is different about sewer line repair in San Diego?
The terrain makes San Diego laterals less predictable than in a flat city. A house on a canyon rim may drain downhill to a sewer in the canyon instead of the street, through a long line on a steep slope that is hard to reach with equipment. Ask for the camera to run the full length so you know where the line goes before anyone prices a repair.
Because your responsibility reaches the main, a defect under the street involves right-of-way permits and pavement restoration. That is where lining or pipe bursting can save the most. In 1950s and 1960s slab tracts such as Clairemont, the cast-iron drains under the house are a separate question from the lateral outside, so have both looked at.

Sewer laterals and tree roots
Clay and cast-iron laterals crack and admit roots. Because the owner is responsible for the lateral to the main, including the part under the street, a camera inspection is worth having before a repair is quoted.
What to check and ask before work starts in San Diego
- Ask where the lateral runs: to the street or to a canyon sewer
- Ask for the camera video and the location of each defect
- Confirm ownership with the Public Utilities Department before work under the street
- Verify the contractor's C-36 license and who pulls the Development Services permit

Sewer Line Repair questions from San Diego
Does the City of San Diego fix sewer laterals under the street?
Generally no. In the City of San Diego the owner is responsible for the lateral up to its connection at the main, including under the street. Confirm with the Public Utilities Department, since other cities in the county differ.
My house backs onto a canyon. Where does my sewer go?
It may connect to a sewer main in the canyon instead of the street. A camera inspection with a locator will trace the route. Canyon laterals are longer and harder to reach, which affects how a repair is done.
