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 high and 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
