According to the NYC Department Of Environmental Protection:
The majority of New York City’s sewer system is combined, which means it is used to convey both sanitary and storm flows. Sometimes, during heavy rain and snow storms, combined sewers receive higher than normal flows. Treatment plants are unable to handle flows that are more than twice their design capacity and when this occurs, a mix of excess stormwater and untreated wastewater discharges directly into the city’s waterways at certain outfalls to prevent upstream flooding.
