Attending one of the first Pumper & Cleaner Environmental Expos in Nashville, Tenn., was a turning point for Mark Hacker, co-owner of Hacker Plumbing and Drilling in Vincennes, Ind. It convinced him to concentrate more on the onsite industry.“We had installed conventional gravity systems since the late 1960s, but it was more of a sideline to the well drilling business,” says Hacker. “I saw the future at the show, and it was advanced secondary treatment and commercial systems.”While the center of Vincennes is sewered, many of its 25,000 residents have onsite systems with failing drainfields and limited space for replacements.
