What is the Muir Beach Water System?

The MBCSD has been providing water to residents 24/7 365 days per year since 1958.  As some residents will remember, in years past, it could be heavily laden with minerals and turn your white clothes brown.  Over the years, our water system has greatly improved and is now meeting increased regulatory standards for public health and safety as well as higher environmental standards as we source our water from the Redwood Creek Watershed.  To stay compliant with new State health and safety regulations, along with a goal to improve the quality and efficiency for delivering safe water, the MBCSD has also increased treatment, monitoring, and management to keep up with new technologies and required governmental reporting.

With only 156 paying customers, our MBCSD Water District is small compared to neighboring systems, and yet our distribution system spans over 2.5 miles with waterlines and infrastructure that needs to be maintained, along with two Service Wells, a Chlorine and Silica Treatment Plant and Pump house, a newly built (2010) earthquake-safe 200,000-gallon water tank, and an aging 100,000-gallon redwood water tank.  All together the system can provide up to 45,000 gallons of water per day with an average of 12 days storage capacity.  The Silica treatment has greatly improved water quality.  Increased monitoring, for both daily chlorine testing and monthly bacterial sampling, has enhanced the safety and confidence in our water supply.
