Water Treatment & Storage

McCarrons Drinking Water Treatment Plant

St. Paul, MN, USA

Description

The almost $250 million upgrade project of the plant comprised improvements to all the pre-filtration stages of the treatment process, including enhancements for removing water hardness, improving water clarity, adjusting pH levels, and eliminating contaminants and pollutants.

The major construction project components include:

  • New source water conduits from the terminal chambers to the water plant.
  • New lime softening solids contact clarifiers to replace existing rapid mix, flocculation, and settling basins.
  • New recarbonation basins to replace the single existing recarbonation basin.
  • New ozonation treatment process for enhanced taste and odor control, oxidation, and disinfection.
  • New chemical systems and new lime storage and handling building.
  • New laboratory, office spaces, and control room.

Products Used

Once added to the concrete mix, the active ingredients in PENETRON ADMIX SB create a crystalline network to prevent water and chemicals from entering the pores, capillaries, and microcracks in concrete, even under the constant hydrostatic pressure in a water tank and water treatment plant. Its ability to permanently self-heal any future microcracks prevents any damage from occurring over the service life of the concrete.
