Bursting pipes. Leaks. Public health scares.

America is facing a crisis over its crumbling water infrastructure, and fixing it will be a monumental and expensive task.

Two powerful industries, plastic and iron, are locked in a lobbying war over the estimated $300 billion that local governments will spend on water and sewer pipes over the next decade.

It is a battle of titans, raging just inches beneath our feet.

“Things are moving so fast,” said Reese Tisdale, president of the water advisory firm Bluefield Research. And it’s a good thing, he says: “There are some pipes in the ground that are 150 years old.”

How the pipe wars play out — in city and town councils, in state capitals, in Washington — will determine how drinking water is delivered to homes across America for generations to come.
