In-Hardstand Tactical Vehicle Maintenance Facilities--Concept Design and Preliminary Recommendations for Wastewater Treatment.

摘要

Maintenance performed on Army tactical equipment -- defined in terms of oil changing and vehicle cleaning -- was reviewed and several alternative plans for controlling waste discharge from Army motor pool vehicle washing and cleaning were considered. (1) Pretreatment of waste discharges from existing washracks and motor pool shop drains with effluent discharge to sanitary sewers. (2) Provision of a separate, industrial waste-collection system with centralized treatment of collected wastewater. (3) Replacement of the existing washrack system with one or two consolidated tactical vehicle wash facilities that have centralized wastewater treatment for discharge or recycle. Alternative 3 was selected as having the most potential for providing an efficient means to regulate effluent discharge. Based on this consideration, concept designs for in-hardstand maintenance facilities were developed. In addition, preliminary recommendations for the design of wastewater pretreatment units were developed, under the assumed condition that gravity separation alone would be sufficient to regulate effluent discharge to an installation's sanitary sewer system.
