If you have a public sewer emergency, such as a manhole overflow, leaking pipe or smell or see sewage on the ground, please contact us immediately for 24-hour response at 415-259-2949.
There are three distinct types of sewer and/or stormwater structures that may call for three different responses:
Overflow Devices - When blockages form in the sewer main or in a private sewer lateral, wastewater can back up in the pipe create an overflow. Overflow devices prevent sewage from backing up into a building and instead release the wastewater outside into the landscape. Contact a licensed plumbing contractor if you suspect the overflow is being caused by a blocked private sewer lateral. If you see a spill coming from the street, manhole or near a creek, it may be coming from a public sewer. Contact the District immediately at 415-259-2949.

Manhole Structures - These are usually located in the middle of the street and provide access for pipe inspection and cleaning. The District’s manhole structures vary from 25 to 42 inches in diameter and are normally have "Sanitary Sewer" printed on top. Contact the District immediately at 415-259-2949 to report an overflow.
Storm Drains carry rainwater only and are usually under curb openings in the gutter, with a grated or slotted piece of metal cover. Contact your local Public Works Department or the Marin County Department of Public Works at 415-499-6570 to report problems with storm drains.
