Water Source & Treatment Capacity Expansion


The City of Whitefish currently operates a Water Treatment Plant (WTP) that treats water from Haskill Creek and Whitefish Lake.  While there are 4 – 1 MGD filters in the plant, the firm capacity is rated by the Montana Department of Environmental Quality (DEQ) at 3.0 MGD, which requires that one filter be taken out of service.  Although this may only be a concern for a few days a year during peak demand season, DEQ has required the city to apply for a deviation to operate above our firm capacity in order to allow any water main extension, subdivision, or future growth.   This deviation is only a temporary solution, and the final solution will require an increase in the treatment capacity of the water plant.

The City selected Morrison-Maierle, Inc. (MMI) to design and oversee construction for the planned water source and treatment capacity expansion project.   In addition to the actual expansion of our water treatment plant, there are several other elements that will need to be accomplished to expand capacity.  These projects include:  

  • Expansion of the Whitefish Lake Intake Pump Station 
  • Installation of a Parallel Water Main to the Water Treatment Plant
  • Extension of the City’s Sanitary Sewer to the Water Plan

Swank Enterprises was awarded the project, work will begin on August 10, 2020.
