Reservoir Road

Work has started on the Water Source and Treatment Capacity Expansion project. Work will continue until the onset of winter conditions when a winter shutdown will take place. 

Temporary asphalt surfacing will be provided for the winter. The remaining work will begin in the spring of 2021. All work will be complete by May 31, 2021.

  • Removal and milling of existing asphalt concrete pavement
  • Expect traffic to be reduced to single lane travel.
  • New natural gas main by Northwestern Energy
  • New 24” water transmission main
  • Water users connected to the City of Whitefish public water supply may experience brief outages when a temporary water supply is being connected, and again when the permanent water supply is restored. This will be further coordinated with individual water service users approximately two weeks in advance of any work affecting water service.
  • New 8” sewer main
  • New asphalt concrete pavement road surface
  • The work will begin at the intersection of Reservoir Road and Wisconsin Avenue and extend along Reservoir Road for approximately a half mile towards the east up to the water treatment plant.
    The City of Whitefish currently operates a Water Treatment Plant that treats water from Haskill Creek and Whitefish Lake. The work in Reservoir Road is being completed as part of the City’s Water Source and Treatment Capacity Expansion Project, which will expand the plant’s total capacity from 4 million gallons per day to 6 million gallons per day.

Winter Update 2020

Construction is well underway at the water treatment plant.  The largest inconvenience to the public is now complete as Northwestern Energy has finished the relocation of their natural gas facilities in Reservoir Road along with the installation of the deep sanitary sewer.  Additional work in Reservoir Road is required next spring to construct a large distribution watermain to handle the increased capacity of the plant, however this work is not expected to require the same delays as the construction that took place this fall.  Temporary asphalt trench patches will be placed this fall and permanent roadway repairs will be completed next year upon completion of the watermain construction.   The new contact adsorption clarifiers are expected to arrive in December along with the precast wall and roof panels for the building expansion.  Installation of the clarifiers will allow the wall and roof panels to go up so Swank can continue work through the winter.  Permanent stabilization of the slope has been completed with drilled soil anchors and the creek bypass work has been completed.  Both of these tasks were required to allow for the expanded building footprint.   To date To date, Swank has billed $1.1M of a $9.3M contract.
