Origin2023
McWane Inc., the Birmingham Alabama parent company, is a vertically integrated water infrastructure products conglomerate that uniquely controls multiple consecutive links in the same supply chain: it makes the ductile iron water mains (through McWane Ductile) AND the gate valves (through Kennedy Valve, founded 1877) AND the fire hydrants (through Clow Valve, founded 1879, and M&H Valve) that together form the complete buried water distribution system. Kennedy Valve and Clow Valve are among the oldest continuously operating valve manufacturers in the United States — both were founded in the post-Civil War era when US cities were first installing centralized water systems. McWane Inc. assembled these century-old valve businesses alongside its DIP pipe business, creating a single company that can supply an entire water main installation from pipe to valve to hydrant. The municipal water utility that buys McWane DIP pipe for its mains, Kennedy gate valves for isolation, and Clow fire hydrants for fire protection is buying all three from the same privately-held Birmingham company, which simultaneously faces questions about historical safety and environmental compliance at its foundry facilities — the same company whose integrated water infrastructure product portfolio is critical to US municipal water reliability.
