McCarrons Water Treatment Plant Improvements - 1900 Rice Street

Saint Paul Regional Water Services is proposing significant improvements to its McCarrons Water Plant located at 1900 Rice Street. Major project components include:

  • New source water conduits from the terminal chambers to the water plant.
  • New lime softening solids contact clarifiers. These will 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.
  • Demolition of existing flocculation basin 3, recarbonation basin, and Clarifiers 1 through 5.

The project is tentatively planned to begin in March 2022, with an anticipated completion date of mid-2026.
