We want to ensure your work does not impact our gravity underground sanitary sewer system so our USA North 811 response will direct you to a map of our known underground facilities. Please view the map and print a location map(s) of your work area. Only our pressure underground facilities will be field mark in accordance with California Government Code Article 2, “Regional Notification Center System,” Section [4216 – 4216.24].
Any work performed on the District's underground facilities or work performed on private plumbing system connected to District's underground facilities will require a District permit.
