PWTB 200-1-138 Evaluation of Centralized Vehicle Wash Facilities for Invasive Species Removal  


The purpose of this Public Works Technical Bulletin (PWTB) is to transmit information on proposed improvements for Centralized Vehicle Wash Facilities (CVWFs) in removing propagules (biological material used to propagate via dispersal, i.e., roots, stems, leaves, etc.) of Non-native Invasive (plant) Species (NIS) from military vehicles. The efficiency of new CVWF technologies assessed by this evaluation could indicate potential for improved CVWF practices worldwide or alternative methods for areas with restricted water resources. This document defines efficiency as the increase in potential NIS removal and the minimization of water consumption throughout the removal process. This bulletin present the methodology used in data collection and study, as well as an analysis of the results.
