Maintaining Infrastructure is Top Priority

Marin Water provides safe, reliable, local drinking water to 191,000 customers spanning 10 towns and cities in a 147-square-mile section of central and southern Marin County. Updating the District’s aging infrastructure, such as this portion of the 120-year old Barber Avenue pipeline, is critical to ensuring the reliability and resiliency of the district's water service delivery system for many years to come.
