Water Treatment Plant Improvements

The City and Borough of Wrangell (CBW) owns and operates a Class 2 Public Water System, under which the current water treatment plant was constructed in 1999.  The demand for potable water within the community has grown and surpassed the design limits of the plant.

Following development of a Preliminary Engineering Report (PER) and a pilot study of the preferred alternative, the CBW pursued the design and is now in construction of a new water treatment plant to improve water treatment capacity, to address challenges with the quality of drinking water for compliance with Federal and State drinking water regulations and to improve our production capacity to meet the community’s growing water demand.  The recommended alternative identified in the PER is to construct a Dissolved Air Filtration (DAF) with Multimedia plant. 

The total cost of the project is approximately $23,300,000.  The CBW funded the engineering design of the project and secured construction funding from the United States Department of Agriculture, Rural Development, the Economic Development Administration, the State of Alaska, ARPA/Coronavirus Local Fiscal Recovery Fund, the State and Local Fiscal Revovery Fund, and the Alaska Department of Environmental Department, State Revolvoing Fund. 

The project serves to renovate the existing water treatment plant system and facility by repurposing existing infrastructure and constructing a new Dissolved Air Flotation (DAF) with Multi-Media Filtration water treatment system to increase the throughput of water to meet the growing water demand, expand storage capacity, and improve the quality of drinking water to meet federal and state drinking water regulations.
