Maintaining Infrastructure is Top Priority

Marin Water provides safe, reliable, local drinking water to 191,000 residents spanning ten towns and cities in a 147-square-mile area of the county. Updating Marin Water’s aging infrastructure, such as the 100-year old E. Blithedale pipeline, is critical to ensuring the reliability and resiliency of the district's water service delivery system for many years to come.
