Chokepoint2003
McWane Inc. is the dominant US ductile iron water pipe maker — and has been convicted or cited for more environmental and workplace safety violations than virtually any other US manufacturer, yet continues to supply the pipes that deliver drinking water to hundreds of millions of Americans McWane Inc., a private Birmingham Alabama company, controls ~55% of US ductile iron pipe production through subsidiaries Atlantic States Cast Iron Pipe, Clow Water Systems, and Tyler Union. Between 1995 and 2005, McWane facilities accumulated more than 450 environmental violations; multiple workers were killed in accidents that OSHA found were preventable. A 2003 New York Times/Frontline investigation titled "Dangerous Business" documented mercury dumping, asbestos exposure, and falsified safety records. Multiple McWane executives were convicted of federal crimes (2005-2008). Despite these convictions, McWane's market share has remained stable; Buy America provisions in federal water funding effectively exclude competing import suppliers and insulate the domestic duopoly (McWane + ACIPCO).
New York Times ↗Did you know2024
McWane, Inc. — parent of Manchester Tank, the second-largest US propane cylinder manufacturer — is simultaneously one of the largest manufacturers of water and sewer infrastructure in the United States: ductile iron water pipes, fire hydrants, and valve fittings for municipal water systems. McWane's pipe and hydrant divisions (Tyler Pipe, Clow Valve, M&H Valve, Mueller) supply the water infrastructure of hundreds of US cities. The same private Birmingham, Alabama company that makes the tanks holding rural America's propane also makes the pipes and hydrants that supply America's urban water. McWane has been the subject of major OSHA enforcement actions for workplace safety violations at its facilities across multiple states.
