As Prime Consultant, PDC performed due-diligence condition assessment and strategic planning studies to support Doyon Utilities’ 2008 takeover of the water and sewer utility systems at Alaska’s three Army posts. During the transition period from government to private operation, Doyon desired to quantify the water and sewer systems and their condition in a characterization study for each fort. Strategic planning to identify the best direction to take the utilities for the next 50 years was also mandated.
PDC’s team evaluated water supply, storage, and treatment facilities at all three posts; a total of 92 miles of water distribution pipes (40 miles within utilidors); 56 miles of sewer collection system (20 miles within utilidors), including 22 lift stations; and sewer treatment facilities including two lagoons and an Imhoff tank. Existing water and sewer models for Fort Richardson and Fort Wainwright were converted to current versions of Bentley WaterCad and SewerCad models. For Fort Greely, PDC staff created a new model based on GIS information from the Army.
