A study was conducted to evaluate the usage of a Zero Discharge waste treatment unit for a highway safety rest area. This evaluation concerns a concept developed by the Thiokol Corporation and took place during the period of July 16-September 26, 1973, at the westbound Echo Rest Area on Interstate 80 in Utah. This report is intended to evaluate the feasibility of a physical-chemical waste treatment unit as an alternative to disposal of sanitary waste at highway rest areas when conventional biological treatment is not feasible. The data presented is as reported to or observed by the writer on field visitations. Laboratory analyses were conducted by Ford Laboratory Inc., Salt Lake City, Utah. The Utah State Department of Highways has experienced inadequate water supplies for operation of rest area facilities and difficulties in locating septic tank drain fields to dispose of wastewater. Despite the unpleasant experiences, the Department maintains a firm policy to have sufficient rest area facilities for the safety and comfort of the traveling motorist. Results of the study have been generally successful with the exception of the sludge incineration process. It was, however, perfected by the Thiokol Corporation on a continuous demonstration of the same unit, in cooperation with EPA at Park City Ski Resort, Summit County, Utah. It is concluded that the Zero Discharge System is another technical advancement which allows highway authorities to provide necessary comfort facilities, which would be impossible using conventional methods to meet modern environmental requirements.
