Construction Updates

Marin Water Worker with Mt. Tam in the background

Marin Water is proud of its rich history as California’s first municipal water district, established in 1912. With that distinction, comes the responsibility to address aging infrastructure. Many of the district's pipelines are more than 100 years old. The Capital Improvement Program responsibly replaces aging pipelines with pipes that better withstand earthquakes and have greater overall reliability. For any construction project questions, please contact the Engineering Division at 415.945.1560.

 

Active Construction Projects

Courtright Systems Improvement Program

Marin Water will decommission and remove a nearly 50-year-old redwood water tank, the Courtright Tank, replacing the leak-prone tank through a series of system improvements that will remove the need for a water tank in the area. The 50,000-gallon tank is located in the Bret Harte Road area of San Rafael, and it will be replaced via the installation of 520 feet of 8-inch pipe, as well as a new pressure regulator valve. Work is scheduled to be complete this winter.

The 2022 Corrosion Test Station Rehabilitation Project

This project replaces corrosion controlling magnesium anodes at dozens of corrosion test sites through the late fall. The 60 anodes to be replaced are just a small portion of the District’s nearly 7,000 magnesium anodes that are used for cathodic protection. Part of a successful anti-corrosion program for the past 30 years, cathodic protection is the process of diverting corrosive processes to magnesium anodes to protect our water delivery system and ensure clean, reliable water delivery.

Fire & Fuels Management 

With nearly 22,000 acres of public land within the Mount Tamalpais Watershed and the hills of west Marin under our care, the District continues to engage in critical vegetation management work. The ongoing, strategic efforts follow the District's Biodiversity, Fire and Fuels Integrated Plan, which is designed to not only reduce the risk of devastating wildfire, but also bolster ecological health through the removal of invasive plant species.

San Geronimo Treatment Plant Emergency Generator Project

This project will install three large, permanent generators at the District's largest treatment plant.  Slated for completion in April 2023, the emergency generator project saves ratepayers money and enhances Marin Water's resiliency by assuring our ability to produce treated water even in cases of PG&E-initiated Public Safety Power Shutoffs during periods of high fire danger.
