This project, sponsored by the Alaska Department of Environmental Conservation’s Village Safe Water program, is providing 1) a new regional septage facility, operated by the City of Anderson, to serve the Denali Borough and the City of Nenana and 2) a wastewater collection system and community lagoon for the City of Anderson.
PDC updated a previous feasibility study, identified and evaluated site alternatives for the septage facility and wastewater lagoon, and designed the piped sewer and lagoon facilities.
Construction of the regional septage disposal facility was completed in 2007. This facility has two primary cells for receiving and dewatering the sludge in preparation for freeze/thaw conditioning. A facultative cell treats the liquid from the primary cells before it is discharged to a percolation cell. The conditioned sludge is transferred to an on-site monofill.
