You can report a sewer backup or flooding in a building after an event, even if the condition has cleared and the water is gone.

What You Need

You must provide your contact information so the Department of Environmental Protection (DEP) can contact you, if necessary. DEP cannot action the Service Request without it. 

What Happens Next

DEP will inspect the location within 6 hours of getting the complaint, however a heavy storm or large snow melt may cause inspection delays.

The City does not respond to sewer problems on Roosevelt Island. You can report the problem directly by phone.

  • Agency: Roosevelt Island Operating Corporation
  • Phone Number: (212) 832-4540
  • Business Hours: Monday - Friday: 9 AM - 5 PM

If the condition occurred during a heavy rain, you do not need a Department of Environmental Protection complaint number to file a claim with the Comptroller's office against the City.
