865,000 GALLON ABOVE GROUND STORAGE TANK

  • Project Location: Camden, ME
  • Services Provided:
    • Geotechnical consulting for replacement water storage tank.
  • Project Summary:
    • Water tank is 102 feet in height, 38 feet in diameter, with a storage capacity of approximately 865,000 gallons. 
    • The above ground tank includes a ring wall foundation with a flexible membrane liner system.  
  • Project Challenges / Innovation: 
    • Geotechnical challenges included a steep side slope requiring a 10-foot cut/fill resulting in the use of a retaining wall. 
    • Subsurface conditions consisted of glacial till containing frequent cobbles and boulders overlying bedrock. 
    • Groundwater springs were present within the glacial till from runoff generated by the adjacent hillside. 
    • The retaining wall consisted of a Stone Strong gravity wall. 
    • Ground improvement included stabilization with geotextile fabric and crushed stone for stabilization of the tank foundations. 
    • An upslope cutoff drain was also incorporated to provide drainage for the seasonal groundwater springs.
