New York

New York City (NYC) has the largest unfiltered water supply in the United States. More than 9 million customers and visitors rely on three extensive reservoir systems, including 19 reservoirs and three controlled lakes, which hold a storage capacity of nearly 2.2 trillion litres. This system was meticulously designed as an interconnected network that has ensured a flexible, reliable and resilient supply of drinking water for more than a century. Rain water and wastewater is conveyed via a 12,070-km network of sanitary storm and combined storm sewers, and treated by 14 large municipal wastewater treatment plants. Currently, longrange planning and adaptive management efforts are being undertaken by the city to address the challenging impacts of a growing population, aging infrastructure and climate change.
