Hill Air Force Base (AFB), UT, is responsible for the operation and maintenance of the Utah Test and Training Range (UTTR). The range contains waste-water treatment and disposal facilities that consist of two infiltration ponds operated in parallel, followed by an emergency overflow basin that safeguards against unexpectedly high flow rates. A previous evaluation concluded that the existing facilities should be replaced, at a relatively high cost and with no possibility for beneficial water reuse. The U.S. Army Construction Engineering Research Laboratories (USACERL) was requested to further evaluate the system and to identify cost-effective, feasible alternatives. USACERL researchers identified a potential process train that included retention of the existing ponds, use of a constructed wetland for further treatment following the ponds, construction of a small basin following the wetland to improve wildlife habitat, and the possibility of pumping treated effluent back to the built-up portion of Hill AFB for reuse as landscape irrigation.
