DeWind’s flagship Service “The One-Pass Groundwater Recovery System” (also known as Ground Water Collection Trench or Seepage Trench). This complex multi-tasked One-Pass operation was developed by DeWind exclusively for installing DEEP groundwater and product recovery systems in HIGHLY contaminated soils with high water tables. DeWind One-Pass Trenchers are designed to set a large diameter steel sump casing, pre-connected to a horizontal slotted HDPE SDR 11 collection pipe. The sump is set and the horizontal pipe is installed on a precise grade while being backfilled with a wall of stone all the way to the surface. All this is done in a SINGLE simultaneous operation by the DeWind Trencher. One-Pass Technology avoids DEWATERING, PUMPING AND TREATING OF CONTAMINATED WATER, TRENCH SHORING OR SHEETING, DANGEROUS OPEN EXCAVATIONS, TONS OF CONTAMINATED SPOILS TO MANAGE! DeWind installations are fast and safe, unlike obsolete conventional installations.
