Drinking Water Tank Inspection Reporting

Reminder of Annual Drinking Water Tank Report Submission Requirements

The annual inspection and water quality (bacteriological) sampling for your drinking water tank must be conducted between January 1 and December 31. The inspection report must be submitted by your certified water tank inspector by January 15 of the following year. For more information, see:

Annual Drinking Water Tank Inspection Report Submissions and Important Reminders (PDF)

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.

Drinking 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.
