Presentation Key Points
• What are we
• Why are we
doing?
doing it?
• What is your role as decision makers?
Council Role in Water Supply
Planning.
• 2005 legislation - "Carry out planning
activities addressing the water supply
needs of the metropolitan area" (MN
Statutes, Sec. 473.1565)
• Twin Cities Metropolitan Area Master
Water Supply Plan — 2010
Ensure a sustainable water supply for
current and future generations
"...water use is sustainable when the use does
not harm ecosystems, degrade water quality, or
compromise the ability of future generations to
meet their own needs."
-- 2009 Minnesota State Legislature
(in directing the creation of Minnesota Water
Sustainability Framework through CWF
appropriation)

Project Goals
• Determine if it is worthwhile to pursue combining utilities
• Financial implications of
combining systems
•Possible next steps (future work)
— Identify best water source for combined utility
— Distribution system modeling
— Refine capital and operating costs
— Revisions to population projections and planned land use, as
available

Expectations
•The scope of the current study is limited to high
level analysis- identification of fatal flaws
• Further investigation will be
necessary to refine details ♦ I
