You can report water flowing from a sewer outfall pipe during dry weather. Each outfall has a sign with the Outfall identification number (ID) assigned to it by the NYS Department of Environmental Conservation (DEC). You will need to provide the Outfall ID when you report a dry weather sewage discharge. The Outfall ID consists of the 2 or 3 character abbreviation of the Wastewater Treatment Plant followed by a 3-digit number. Examples include RH-034 and 26W-005.
