"Reverse osmosis is a very specialized process, so we were looking for a partner that would be here today and tomorrow, especially given all of the mergers and acquisitions in this field. Harn’s past clients were so overwhelmingly complimentary about the entire company’s commitment to its projects from start to finish and beyond that we knew we would get what we really needed."
