The U.S. Army Corps of Engineers designed and built several successful Central Vehicle Wash Facilities (CVWFs) to allow the exterior of tactical vehicles to be cleaned in an efficient and environmentally safe manner. Because designers believe the guidance for secondary treatment design was too restrictive, research was initiated to investigate alternatives for CVWF treatment systems. The objective of this study was to evaluate alternatives or modifications to existing design guidance for CVWF secondary treatment. Research revealed that intermittent sand filtration, lagoons, and constructed wetlands are acceptable for secondary treatment. All three alternatives will function with little attention from the CVWF operator. Lagoons and constructed wetlands will require little maintenance. Sand on the surface of intermittent sand filters will need to be removed periodically. All three types of secondary treatment provide water that should be discharge quality in most states and will not be a hazard to the troops using the facility.
