Millions of Americans take water service for granted every day. Turn on the tap, and clean water flows out. Flush the toilet, and dirty water goes away. With reliable water service, people don’t have to think twice about the infrastructure that brings water to their homes, and then safely recycles it or returns it to the environment – but everyone should be concerned with the future of those systems. Today, October 23, 2019, is the fifth annual Imagine a Day Without Water, a nationwide day of advocacy about the value of water organized by the U.S. Water Alliance.
