Statement of Basis and Purpose



The Administrative Code requires that any owner of a building that has a water tank as part of its drinking water delivery system must have the drinking water tank inspected at least once a year. The inspection must comply with all applicable laws and regulations, including provisions of the Health Code. The results from these inspections must be recorded in a manner set out by the Department’s Commissioner and maintained for at least five years.

Water for thousands of New York City buildings is kept in drinking water storage tanks. The Health Code sets out requirements for maintaining the purity and sanitary condition of the City’s drinkable water supply. The Health Code requires that these drinking water tanks be inspected annually and that the person in control of a building serviced by a drinking water storage tank keep copies of the inspection records and make them available to the Department upon request.

Building owners with drinking water tanks must report annually to the Department after the tanks have been inspected that the inspection has occurred. Annual reporting promotes building owner compliance with the inspection requirement and facilitates the Department’s ability to monitor compliance.  The Department will make data from the reports publically available. These rules specify how the recording and reporting of the drinking water tank inspection must be communicated to the Department.

New Chapter 31 will:

  • Allow for both electronic and paper-based reporting of annual drinking water tank inspection results through either an interactive online form or a printable form available on the Department’s website.
  • Set the deadline for annual drinking water tank inspection result submissions to be no later than January 15 of the following calendar year for which the inspection is due.
  • Make drinking water tank inspection documents filed with the Department available to the public.
