How do I proceed with a sewer lateral repair problem?

If the sewer problem is found to be in the upper sewer lateral (JPEG) (between the building and cleanout at the property line), the property owner is responsible for repair and can hire a plumbing contractor or make the repairs themselves. Contractors are listed in the yellow pages of the phone book under "Plumbing Drain and Sewer Cleaning" or "Sewer Contractors." If you plan to hire a contractor, we recommend getting estimates from more than one company.

Before doing any work on a sewer line, including installing a cleanout, you need to obtain an Inspection Permit from the Napa Sanitation District. More information on how to get a permit is available by calling us at 707-258-6000. Cleaning a lateral line through an existing cleanout does not require a permit. Once you are aware of a sewer lateral problem, it should be repaired as soon as possible. Sewer laterals that leak or overflow are a public health risk and may cause damage to the environment.
