Call (833) 571-0120Rancho San Diego ZIP 92019: describe your street on a call
Rancho San Diego sits southeast of La Mesa along Jamacha Road, with Cuyamaca College and the library as its best-known landmarks. The Census matched those addresses to ZIP 92019. Describe your street on a call and we will say what is possible. The sections below show which agency serves the water and the sewer at your address.
The lateral is yours up to the main
Otay says property owners are responsible for sewer laterals up to the connection at the sewer main. A camera inspection tells you which side of that connection holds the problem. If the blockage is in the main, the agency that owns it responds.
Sewage in this area ends up at the Metro facility at Point Loma, and part of the flow is recycled at Otay's Chapman facility. That is background, not a homeowner task. For a backed-up lateral, fixing a cracked lateral explains the repair options, and high-pressure line scouring is one way to clear roots and grease.
