New York City's Wastewater Treatment System

How Water Gets to Us

When you take a shower or brush your teeth, do you ever wonder where the water comes from? Or, where it goes? You’re about to learn how water gets to us and what happens to water once it disappears down the drain. In both cases it travels through a remarkable system of pipes.
