Clean and plentiful water is essential for life. New York City has the largest municipal water system in the United States. More than 10 million people rely on this complex of reservoirs and aqueducts, some of which are more than a century and a half old. In this podcast we learn about the structure, history, and current state of the New York City water supply system from Kevin Bone, Professor and Director of the Institute for Sustainable Design at the Irwin S. Chanin School of Architecture at The Cooper Union in New York City. His edited book, Water-Works – The Architecture and Engineering of the New York City Water Supply System, Monacelli Press, 2006, describes the development of the fresh water system for New York.
