Reopening Businesses & School Buildings: Water Quality Precaution Advised

(Posted October 19, 2020)  As Marin County implements gradual, phased reopening of business and school buildings that were dormant for months,  NMWD suggests you fully flush your building’s plumbing by running water from cold taps for several minutes before using.  Flushing will remove any water that has become stale and has lost quality while in contact with metal plumbing and from dissipation of chlorine disinfectant.  NMWD staff are ready to answer your questions or help with water related problems you may be experiencing.
