Marin Water continues to work with the City of San Rafael through the city's 3rd Street Rehabilitation Project in an effort to shorten the project schedule and reduce inconvenience for residents. The full 6,570 feet of new pipeline, including 54 water service laterals, is expected to be complete in September 2022.
