United Marine International (UMI), Division of Liquid Waste Technology, Inc., USA, has emerged as the world's leading producer of Marine Trash Skimmers. UMI designs and manufactures Water Management Boats to remove from waterways all types and sizes of floating debris, aquatic vegetation and related pollutants...anything and everything that "washes" out of watersheds after snow melts, "spring runoff" and rainstorms...natural debris, street litter, man-make "flotables", and garbage. All this pollution eventually finds it way into our ports and harbors. Today there are over 60 UMI TRASHCAT™ skimmer boats in operation throughout the world.
