| In 1992, our founder created and patented the first portable, self-contained system that removed sand and grit from wastewater treatment plants while they remained in operation. This system evolved into what is now known as the “Vertical Grit Separator.” (VGS) The Vertical Grit Separator (VGS) is the only proven patented “state-of-the- art” portable degritter that removes sand and grit from wastewater treatment facilities while the plant stays in operation. |

| Sand and grit removal is the most inexpensive repair that can be made to a wastewater treatment facility to achieve greater effluent efficiency. |
