Return to work: Precaution advised for building owners

(Posted May 15, 2020)  As Stay-At-Home orders are lifted and you begin to return to buildings that were dormant for weeks,  NMWD suggests you flush water from cold taps for several minutes before using.  Flushing cold water will remove any water that has become stale and may have 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. Contact us by email or call 415-897-4133

More information and guidance on procedures to restore water quality for building owners and operators can be found on the US EPA’s website:
