Sewer Line Replacement in Del Mar, CA

Warning signs

The City of Del Mar notes that most sewer backups come from clogged private plumbing, so a plumber is usually the right first call. Contact Public Works only if you suspect the problem is in the City system.

Del Mar's sewer and why location matters

Del Mar is a small coastal city that puts a lot of weight on keeping sewage out of its beaches and lagoons. City of Del Mar Public Works maintains the public sewer; the lateral that attaches to the city main is the owner's. Because the City didn't install private laterals, it has no records of where they run, so a plumber has to locate yours with a camera and a transmitter before anyone can price a replacement. If repair or replacement reaches into the public right of way, the City requires an encroachment permit from the Planning Department.

Del Mar's water is chloraminated and hard, but that has little bearing on drain pipe. What matters more for a lateral is age, material, roots and how well it was bedded when it went in, and only a camera can show those. For problems in the City's own system, Public Works answers at (858) 755-3294, and after hours North County Dispatch takes calls at 858-756-1126.

What drives the cost

• Locating the line, since there's no city map of private laterals
• Length, depth and any steep grade between the house and the main
• Trenchless methods versus an open trench
• Restoring hardscape, decks and coastal landscaping
• Building permit, plus an encroachment permit for work in the right of way

When you call

You'll be connected with an independent plumber who works in Del Mar. Expect a camera inspection and locate first. Building & Safety Services handles plumbing permits through eTRAKiT, with inspections scheduled at (858) 375-9528. Ask the plumber who files each permit, whether an encroachment permit is needed and how the inspection fits the schedule. It's also worth asking for a marked sketch of where the new line runs, since the City won't have one on file.
