This guidance is intended for building owners, managers, engineers, operators and superintendents.

For all buildings that have been vacant or have had low occupancy due to the New York State (NYS) PAUSE executive order, additional maintenance is needed to restore the quality of the drinking water before a building is reoccupied. Stagnant water that results from low or no use can create health risks. These can include the growth of pathogens (Legionella, Mycobacterium avium and Pseudomonas aeruginosa), leaching of metals (lead and copper), accumulation of sediment, growth of biofilms, taste and odor problems and accumulation of disinfection by-products.

To restore drinking water quality and protect building occupants, download the Guidance for Returning Building Water Systems to Service After Prolonged Shutdown.
