How can I find my private sewer lateral?

For help locating and addressing problems with defective private sewer laterals, please contact a licensed plumbing contractor. Make sure any plumber you hire for a private property sewer emergency is familiar with District policies and programs. Information on licensing can be found here

Your contractor will video the lateral to view and determine the location and path to the public sewer line. The District may have diagrams or information about your property on file. Call us at 415-259-2949 to check for records. Please note that maps or drawings received by the District are not exact or guaranteed.
