The Twin Cities Metropolitan Area Master Water Supply Plan provides a framework for sustainable long-term water supply planning at the local and regional level. The plan provides communities in the region with planning assistance for water supply in a way that:

  • Recognizes local control and responsibility for owning, maintaining, and operating water supply systems
  • Is developed in cooperation and consultation with municipal water suppliers, regional stakeholders, and state agencies
  • Protects critical habitat and water resources over the long term
  • Meets regional needs for a reliable, secure water supply
  • Highlights the benefits of integrated planning for stormwater, wastewater, and water supply
  • Emphasizes and supports conservation and inter-jurisdictional cooperation
  • Provides clear guidance by identifying key challenges, issues, and considerations in the region and available approaches (without prescribing solutions)

The plan provides guidance so that communities can take the most proactive, cost-effective approach to long-term planning and permitting to ensure plentiful, safe, and affordable water that supports the prosperity and livability of the region for future generations.
