1 Privileged and Confidential © 2013 The Weidt Group To understand how to effectively conserve a resource, you need to first understand how you are using it. Big Picture Views Look at annual trends in Water and Energy use and costs across an organization Look at monthly consumption trends (Irrigation vs. Non-irrigation trends) Look at meter data by type – costs & consumption Water (Indoor, Mixed Use, Irrigation Only, Pool, Other, Sewer, Storm water) Compare resource use and costs for different buildings or spaces Submeters allow use and costs of specific activities to become evident Identify greatest opportunities for conservation based on use and costs at each campus See the impact of conservation efforts and upgrades on annual cost and use MnSCU B3 Benchmarking 54 Campuses (Technical, Community, State University)
2 Privileged and Confidential © 2013 The Weidt Group Water Consumption The Big Picture Not all campuses have complete and accurate data. Generally higher irrigation in 2013
3 Privileged and Confidential © 2013 The Weidt Group Water Consumption - Costs The Big Picture Monthly Costs Monthly Consumption
4 Privileged and Confidential © 2013 The Weidt Group The Big Picture – Cost vs Use Higher costs Jun-Oct due to cost of water for campuses with high summer use

6 Privileged and Confidential © 2013 The Weidt Group Case Study Candidates High Water Users Vermillion $17,000-$24,000/year in Water Costs Typical Monthly Cost $300 Reverse trend in water use – Lower summer use Overall reduction in water use 2009-2011 Meter recalibration (10-yr difference) in Nov & Dec 2013 WUI 4,000 – 6,000 gallons/student/year SW MN State $100,000 - $124,000 in water Typical Monthly Cost $1,000 - $1500 Peak Monthly Cost $4,000 Peak summer water use (irrigation) Increase in summer use, decrease in other WUI 5,000 gallons/student/year
