| Summary: | This research memorandum presents and compares estimates of the operating costs of selected flush haul sanitation systems in rural Alaska. The estimates are based on actual operating experience. An accurate picture of operating costs is important when evaluating flush haul systems because communities are generally responsible for paying these costs. People need to know these costs in advance when choosing among alternative systems.In previous work (Colt 1994) I estimated life-cycle costs for prospective flush haul systems in Buckland and Mekoryuk. These systems have now been operating for several years. In addition, flush haul systems have recently been installed in Galena, Napakiak, Nunapitchuk, Quinhagak, Shishmaref, and Tuntutuliak. As part of the Alaska Native Health Board Operation and Maintenance Demonstration Project, we collected operating data from the communities of Buckland, Galena, and Nunapitchuk. Additional data for systems in Mekoryuk, Quinhagak, and Tuntutuliak has been collected by others (Yukon-Kuskokwim Health Corporation 1998). This paper therefore considers the six communities listed above. This work was undertaken with the assistance and contributions of the Alaska Native Health Board Operation & Maintenance Demonstration Project.
