SUMMARY:

Attached for review and comment are the draft wastewater and water supply sections of the Utilities chapter of  the 2040 Comprehensive Plan Update. The Metropolitan Council requires that each community include wastewater and water supply plan elements to their comprehensive plan.

 

Apple Valley is served by the Met Council's regional system; therefore, the update needs to provide a comprehensive sewer plan describing service needs from the regional system. The wastewater plan must be designed to support the population, household, and employment forecasts as described in in the city's System Statement.  The update should also plan and provide for the appropriate local system capacity and address inflow and infiltration (I/I), which is described as clear water that enters wastewater systems, consumes capacity, and increases demand at a wastewater treatment plant. These excessive flows can result in public and environmental health concerns if untreated sewage discharges to basements, rivers, lakes, or other public areas.

 

Included in the wastewater plan shall be the following components:

 

  • Description of the existing sanitary sewer system
  • A table or tables  that detail the households and employment forecasts in 10-year increments through 2040, based on the Met Council's forecasts and any subsequent negotiated modifications
  • Mapping that shows the existing system's lift stations and connection points to the metropolitan system and existing on-site wastewater disposal systems
  • Information on intercommunity flow agreements with adjoin communities, including a map of areas covered by the agreements
  • Tables that contain the capacity and design flows for existing trunk sewers and lift stations, and an assignment of 2040 growth forecasts by Metropolitan interceptor facility
  • Our community goals, plans, and strategies for preventing and reducing excessive inflow and infiltration (I/I) in the local system
  • Describe the extent, source, and significance of existing I/I problems in the community
  • Analyze the costs for remediating the I/I issues in the community
  • An implementation plan that contains a program strategy, priorities, scheduling and financing mechanism for eliminating and preventing excessive I/I from entering the sanitary sewer system

 

Also, all communities like Apple Valley that have a public water supply system in the Twin Cities metropolitan area are required to prepare a water supply plan as part of their local comprehensive plan.  That plan should include the following elements:

 

  • Water demand projections through 2040
  • Potential water supply issues
  • Proposed alternative approaches to meet extended water demand projections
  • Value-added water supply planning efforts
  • Source water protection

 

Nancy Ziegler with AE2S (Advanced Engineering and Environmental Services), the consultant retained by the City to update the wastewater and water supply plans, will make a presentation to the Planning Commission on the night of the meeting.
