NMWD Annual Flushing Program
(Posted January 6, 2020) North Marin Water District 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.
