The City maintains most of the sewer main lines throughout the City, however, the lateral line that connects from individual homes and businesses to the main line is the responsibility of the property owner (MBMC 5.36.240).

If you smell a strong sewer odor in the street, try to locate its source and give us a call, there might be a blockage or a leak. Also, if you plan on having your sewer line flushed or cleaned out, please contact the City first so our crews can be aware of the situation. It is possible that the extra flow from your lateral could block up the main line and cause an overflow. To prevent this from happening, please give us a call 24 to 48 hours in advance of the work being done. You can reach us at (310) 802-5304; our office hours are Monday through Friday 08:00 AM to 04:30 PM or you can fill out a Request for Service Form. If you need immediate assistance after our normal business hours please contact our after-hours call center at (310) 802-5000.

Wastewater from Manhattan Beach is pumped to the Los Angeles County Sanitation District for treatment. To learn more about waste water treatment check out the Los Angeles County Sanitation District's web page.
