***NMWD Suspending Walk-In Customer Service through April 7, 2020***

After careful consideration, and in light of Governor Newsom and the Marin County Public Health Officer’s newest guidance on Sunday, March 15, the District is temporarily suspending walk-in customer service through Tuesday, April 7, 2020. With the health of our community in mind, this decision is a preventative measure aimed at reducing community exposure to COVID-19. Customer service support remains available by phone at (415) 897-4133, by email at, or by appointment. We continue to work closely with our local, county, state, and federal partners. Please know that water service will continue 24/7 and there is no threat to your public drinking water supply.

***North Marin Water District tap water is safe from coronavirus***

Water served by North Marin Water District to customers comes from protected watersheds and is purified using modern treatment techniques to remove pathogens, including bacteria and viruses. Water is continuously monitored to ensure that it surpasses all state and federal regulations for health and safety. As you make any preparations to deal with the risks of coronavirus (COVID-19) know that your tap remains a safe and reliable source of clean, good-tasting drinking water. More information on water quality can be found HERE

***Proposed Rate Changes for Novato Service Area***

NMWD currently bills customers under a rate structure comprised of 16 rates categorized by commercial, residential, elevation zones, and seasons. NMWD conducted a detailed study of the current rate system. This study was carried out by an independent outside consultant who completed a comprehensive cost of service report and rate study to set new water rates that are proposed to go into effect on July 1, 2020.

Learn more about rate structure changes and a revenue increase to enable critical investments in the water system.

***NMWD Annual Flushing Program***

NMWD began its annual water main flushing program starting Monday, January 13th, 2020. This is a standard practice to ensure there is no degradation in water quality and to maintain an adequate chlorine residual (disinfectant) which helps prevent any bacterial growth in the pipelines. Customers may temporarily experience low water pressure or a slight, but harmless color in their water when the flushing is conducted in their neighborhood. Flushing is performed in the winter months when there is sufficient water supply for the task. The 2020 program has been developed to use the least amount of water to maintain good water quality.

***Marin County Multi-Jurisdiction Local Hazard Mitigation Plan (MCM LHMP)***

NMWD has participated in the preparation of Marin County’s 2018 Multi-Jurisdictional Local Hazard Mitigation Plan (LHMP). The District’s participation in the LHMP is a pre-requisite for potential future funding opportunities provided by CalOES and FEMA. More information can be found here.

Advanced Meter Information Project – NMWD is excited to announce that the Advanced Meter Information (AMI) system deployment program is complete. The deployment project began in March 2018 and over 21,000 meters have been upgraded. The District commenced deployment of an AMI system to improve water use efficiency as well as meter reading efficiency, accuracy, and customer service. The project included meter upgrades for customers throughout NMWD’s Novato service territory. With the AMI system, digital meter data is sent securely via radio to NMWD headquarters for billing purposes. This technology provides early leak detection and enables customers to view water use information online, thereby gaining a better understanding of their water use patterns. As a part of the AMI system, a new online payment and WaterSmart Portal has been developed. We encourage you to “sign-in” on the portal to get acquainted with the system and learn more about your water use. Customers will now have access to hourly water use data and are able to set up alerts for high use and leak events on the WaterSmart Portal. Please visit to register. If any customers have issues registering or logging-on to or the WaterSmart Portal, please call 415-897-4133 and a staff member can guide you through the process.
