This is the second installment in a series exploring the top water systems in the United States.
The first installment, “Water is a City”, was published in April 2018.
This time, the authors analyzed water system data from the U.S. Census Bureau.
This year’s article will explore how water systems across the country have changed over time.
“In many ways, water is an evolving asset,” said lead author Michael DeFilippis, a professor of water resources at the University of Texas at Austin.
“What you have in a lot of places is a different mix of people.”
In the past few decades, water systems have increasingly become places where citizens can take charge of their water.
Today, most people are able to access water without a permit, so water systems can take on more responsibilities for managing water.
“The water industry is going to need to grow up,” DeFilios said.
“There’s not a lot that we can do about it, but we can change the way we manage it.”
Some of the water systems listed in this article are owned or operated by private entities.
Water companies are not required to obtain a permit.
