Water Tank Inspection Reporting
Water tanks help deliver drinking water to millions of New York City residents. In buildings with more than six floors, pumps push water to rooftop tanks where the water is stored until needed. When a faucet is opened, water exits the tank and gravity carries the water to the floors below to be used.
Building Owners
Owners of buildings in New York City that use tanks to store or pressurize the building’s drinking water must have the tanks inspected at least once each calendar year, and must submit the results of those inspections to the NYC Department of Health and Mental Hygiene by January 15 of the next calendar year. Inspection reports may be submitted online or by mail. If submitted by mail, the reports must be on the official form (provided below).
