These 10 locations take a look at the history, design, and challenges of our Water Infrastructure systems. Each one represents a small part of whats at stake on a national scale. But understanding the challenges starts with understanding the value of the three basic systems. Generations of americans have never experienced living without a constant, unlimited supply of water delivered straight to the tap, or without their waste flushed immediately away.

In the new york city system, water is collected and stored in 19 reservoirs, which can hold more than a years supply over 580 billion gallons of water. Almost all of the system is fed by gravity, without the use of energyconsuming pumps. Valves open to regulate the flow into the 85milelong Delaware Aqueduct the longest tunnel in the wo
