Since 1912, UA Local 577 members have built and maintained the facilities that provide power to businesses, manufacturers, hospitals, schools, and homes in the Portsmouth and Southern Ohio region. Our plumber-pipefitters build and operate power facilities and the grid our communities depend upon. For generations, UA Local 577 journeypeople and apprentices have mastered the advanced plumbing and pipefitting technologies of their time – and continue to lead southern Ohio into the future.
