About this episode
The episode explores the manufacturing of ductile iron pipes at the U.S. Pipe foundry in Alabama and discusses the sustainability aspects of water infrastructure.
America’s drinking water infrastructure depends on more than 2 million miles of pipe buried beneath streets and communities across the country. In this episode of How Water Works, Jeff Mason leads a tour inside the U.S. Pipe foundry in Alabama to show how ductile iron pipe is manufactured — from recycled scrap metal to critical underground infrastructure. The episode follows the intense process of melting old cars, appliances, and industrial metal into pipe engineered to last for generations and withstand earthquakes, floods, and decades of pressure underground. It also explores overlooked sustainability stories inside heavy industry, including industrial water reuse systems, emissions reductions through electric induction furnaces, and how more than 90% recycled material becomes essential infrastructure. Along the way, Mason explains the chemistry, testing, coatings, and cement linings that help ensure drinking water remains safe and reliable as it moves through these systems. From molten iron hotter than lava to finished pipe headed everywhere from Manhattan to small-town America, the story pulls back the curtain on one of the most important — and invisible — parts of how water…
