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.
Owners of buildings that use tanks to store or pressurize the building’s drinking water must have the tanks inspected at least once per year. They must ensure that the water tank inspector submits the results of those inspections to the Health Department by January 15 of the next calendar year.
Water Tank Inspectors
Water tanks must be inspected by a qualified inspector, who then submits the results to the Health Department. To be qualified, an inspector must meet one of the following conditions:
- They must be a licensed master plumber.
- They must work under the direct and continuing supervision of a licensed master plumber.
- They must be a licensed professional engineer or architect design professional.
