The Pipe That Built Modern Cities | The Story of Cast Iron Water Mains

Cast iron pipe has been moving water and wastewater for more than a century, but how was it made and why is it still found underground today? In this episode of Under Pressure Underground, we dive into the history of cast iron pipe, how it revolutionized water systems, the manufacturing process, common failures, and why many utilities are still dealing with aging cast iron infrastructure. From early sand-cast pipe to modern replacements, we explore the evolution of one of the most important materials in underground construction. #CastIronPipe #UndergroundInfrastructure #WaterMain #SewerSystems #CivilEngineering #WaterIndustry #Utilities #Infrastructure #PipeHistory #UnderPressureUnderground
