What We Do

The District maintains and operates over 210 miles of main line sewer system in the City of Menlo Park and portions of the Cities of East Palo Alto, Redwood City, the Towns of Atherton, Woodside and Portola Valley and portions of Unincorporated San Mateo and Santa Clara Counties.

In addition the District will attempt to clear the sewer line from a conforming cleanout to the main line sewer upon a request to do so. A cleanout must have been installed pursuant to the District’s Code of General Regulations in order to be conforming.

The District provides 24 hour emergency service. Regardless of whether or not you have a conforming cleanout it is recommended that you always contact the District in the event that you are having a problem with your sewer. The District Emergency Response crews always check the main line sewer to ensure that it is flowing correctly. You will be advised if the problem is located in the portion of sewer that the District does not maintain.

To request service please call (650) 321 0384, 24 hours a day. If your parcel does not have a conforming cleanout it is recommended that you install one. A permit must be obtained from the District’s Office between 8:00am – 4:00pm, Monday – Friday. The fee is $490.00 (payable by cash or check) and includes inspection by the District to ensure conformance with the District’s Code of General Regulations.
