We are proud of our rich history as California’s first municipal water district, established in 1912. With that distinction, comes the responsibility to address our aging infrastructure. Many of our pipelines are more than 100 years old. Our Capital Improvement Program responsibly replaces aging pipelines with pipes that better withstand earthquakes and have greater overall reliability.

Current Projects

Sir Francis Drake Boulevard Pipeline Replacement Project

Marin Water is installing a new pipeline under a portion of Sir Francis Drake Boulevard in Kentfield, replacing old pipes that date back to 1920. The new pipeline, which also has features that will improve its seismic reliability, is part of our ongoing work to upgrade aging infrastructure and improve the overall reliability of our system. The cost of the project is $3.9 million, and the majority of the work will occur at night to minimize traffic disruptions. Drivers in the area can expect partial lane closures and some traffic delays.

Construction is being done in tandem with Marin County’s Sir Francis Drake Boulevard Rehabilitation Project to reduce costs and minimize disruptions. Construction began in June and continues through June of 2022. For more information about the County's project, visit
