Stafford Treatment Plant Primary Filter Upgrade Project

(Posted 12/4/24) Recently, North Marin Water District rehabilitated the primary filter basins at the  Stafford Treatment Plant near Stafford Lake. There are three primary filters at the treatment plant, each is designed to treat 2 million gallons per day and they have been in operation since the treatment plant was rehabilitated in 2006. This year, the filters got a much needed refurbishing and upgrade, including new interior coating, new underdrain system, new filter media, additional corrosion protection and new settling tubes for the upflow clarifiers. These improvements took a little longer than anticipated but will extend the life of the filter basins for at least another 20 years, if not more, and increase efficiency of treatment, reliability and water security for the District. The Stafford Treatment Plant provides approximately 20% of the Novato Water System’s supply needs.
