Immediately notify the City at 510-577-3434. If the problem occurs after 3:30 pm or on weekends/holidays, please call the San Leandro Police Department at 510-577-2740. Our crews will locate the blockage and determine whether it is in the public sewer; if it is, the crew will remove the blockage and arrange for cleanup.
If the backup is in your private internal plumbing or in the service laterals, you must contact a plumbing/sewer contractor to address the problem immediately. Public Works staff cannot provide recommendations for contractors.
