Drinking Water Protection: Plan Review for Noncommunity Systems - EH: Minnesota Department of Health

Plan Review for Noncommunity Systems

When is a plan review required for noncommunity systems?

Prior to construction or addition to a water service line:
    • The water service line is defined as the potable water supply system between the water source and (up to and including) the point of entry into the water distribution system.
      • The point of entry is typically the effluent of a pressure tank, expansion tank, or final treatment unit.

      Prior to construction, installation, or coating of any potable water storage, including

    • Ground-level storage tanks
    • Elevated storage towers

    Prior to construction of a well house, pump house, or any building meant to contain a well.

    Prior to installation or alteration of any public water supply treatment system including:

      • All water treatment installations used to remove or reduce regulated contaminants listed in the Safe Drinking Water Act
      • Replacement of existing treatment equipment
      • Changes or modifications to the plumbing of an existing treatment facility
      • Any chemical feed equipment

    When is plan review NOT required for noncommunity systems?

          • Installation of noncommunity water supply wells, unless funded by a Source Water Protection Grant.  Work must still be performed by a licensed well driller, who shall submit a well notification to the MDH, Section of Well Management.
          • Installation of point-of-use devices that are used for aesthetic purposes only.
          • Water softeners used only for hardness, iron or manganese removal.  (Note:  Installation of water softening equipment will subject the system to additional lead and copper monitoring per the Lead and Copper Rule Revisions of 2006.)

    What do I need to include in the plans and specifications?

        • Flow rate
        • Water system demand (including domestic water use, and industrial/process water use)
        • Contaminant concentrations

      • Treatment specifications:
        • Type of filter or softener media
        • Number of vessels and orientation (series or parallel)
        • Chemical feed equipment, including feed rates
        • List of chemicals used for treatment, including feed rates (all chemicals must be ANSI/NSF Standard 60 listed)
        • Makes and models of all equipment (all devices, components, and materials which contact drinking water, must be ANSI/NSF Standard 61 listed)
      • Detailed floor plans showing the locations of the:
        • Proposed treatment equipment
