ETL 13-2 Design, Construction, Operations and Maintenance of Semi-Permanent Wastewater Treatment Plants at Contingency Locations  


This ETL is a guidance document for use in contingency locations or deployed locations outside the United States that require semi-permanent wastewater treatment facilities (WWTF) for 30 to 250 personnel. Guidance exists for initial and temporary facilities (less than 24 months) and for permanent facilities, but not specifically for small contingency locations (30 to 250 personnel). This ETL provides an intermediate step to the methods covered in Air Force pamphlet (AFPAM) 10-219V7,Expedient Methods, and Unified Facilities Criteria (UFC) 3-240-02, Domestic Wastewater Treatment. This ETL presents an approach to design, construction, and operation of treatment systems that provides optimal long-term performance, limits negative effects on local resources, and promotes sustainable water management.
