Almost every time it rains, polluted stormwater runoff mixes with raw sewage in New York City’s combined sewer system and overflows into our waterways where people swim, fish and boat, making it unsafe for contact. We call these “combined sewer overflows.” New York City dumps more than 20 billion gallons of sewage into local waterways each year. That volume could fill the Empire State Building 72 times!
