Who do I contact for sewer back-up emergencies?

Call a plumber to clean out the sewer lateral as most problems originate there. If the problem is not in the property owner’s pipes, contact Sewer Authority Mid-Coastside (SAM) at 650-726-0124. SAM will clear blockages that occur in sewer lines beyond the property owner's lines.

Please contact SAM for other sewer emergencies such as sewage escaping the collection system.
