Advanced Wastewater Treatment Facility Tertiary Treatment Phase 2 Improvements

The City of Coeur d’Alene is constructing improvements at the City’s Advanced Wastewater Treatment Facility, located at 881 W. Hubbard Avenue, to meet National Pollutant Discharge Elimination System (NPDES) permit requirements and to accommodate future flows.  These improvements are a result of the City’s 18 month pilot testing performed in 2010 and 2011 for removal of phosphorus to meet the ultra-low phosphorus limits of the 2014 NPDES permit, and are in conformity with improvements defined in the 2012 Update to the 2009 Wastewater Treatment Facility Plan. 

The improvements will include the procurement and installation of additional tertiary membrane filtration equipment, construction of a third secondary clarifier and associated secondary control building, construction of a third primary clarifier, installation of additional chemical tanks and pumps and other ancillary improvements.

HDR Engineering, Inc. (Boise, ID) is the design engineer for this $20 M project and Apollo, Inc. (Kennewick, WA) is the construction contractor.  The construction of the improvements is scheduled to be completed by December 31, 2018.
