  2. Colorado Springs Utilities • Four service utility providing safe, reliable, competitively-priced electric, natural gas, water and wastewater services to 500,000 people in Colorado Springs and surrounding communities • Fast growing community with economy based on high tech, military, education, services, and tourism • 2008 Budget: $955 Million • Some of the lowest utility rates, nationally, as compared to peers • Multiple J.D. Power awards for customer satisfaction and systems reliability • About 1,800 employees

  3. Outline Water System Overview Water Resource Plan The Southern Delivery System Challenges

  5. Water System • Serves 412,800 people with about • 81,000 acre-feet/year or 26.3 Billion Gallons/year • Growing @ 2.2%/year • Infrastructure reaches over 3 rivers basins and 9 counties. • 25 Storage Reservoirs • 28 Storage Tanks • 1,780 miles of mains • 7 Treatment Facilities • Influenced by activities in Colorado, West, & nationally

  6. Colorado Springs’ water supply • On average 70% of water is delivered from Colorado River Basin • Homestake • Twin Lakes • Blue River • Frying Pan-Arkansas Project • Via 3 delivery pipelines • Otero • Blue River • Fountain Valley Authority • Water from Colorado River tributaries • Reused to extinction via: • exchanges for agricultural uses • in our non-potable system

  7. Terminal Storage Water Treatment Plant Distribution Storage Raw Water Pump Station Land Application Sludge Disposal Waste Water Treatment Plant Lift Station Pacific Storms & snow How The System Works Mountain Collection System TransmissionPipeline Regulatory Storage Customers Customers Exchange Sludge Line Distribution System Non-pot Gravity Interceptor Waste Water Collection System Force Main Arkansas River Basin Systems Discharge to Stream System Exchange

  8. Water Resource Plan • Recommendations from extensive public process, engineering, and economic modeling • Multiple solutions to meet Colorado Springs’ water needs through 2046 • All recommendations currently being pursued • New major delivery system needed for 55% of future water supply 8

  9. Conservation Low per person usage as compared to peers Aggressive block pricing Education and incentive programs Water Resource Plan

  10. Nonpotable water development 13% of water delivered Averaging about 10.2 million gallons/day System improvements 23.2 MGD Otero Expansion Project done in 2003 for +13 MGD, 24% increase for this pipeline Pinello Wells Rehabilitation for 1.8 MGD - 2003 Woodmen Upgrades for 0.8 MGD - 2004 McCleary Wells for 0.6 MGD - 2005 Northgate and Mary Kyer Wells for 1.9 MGD - 2007 Pikeview to Mesa & Highline to Northfield for 4.4 MGD - 2008 Bear Creek Intake for 0.7 MGD - 2008 Water Resource Plan

  12. Outline Water System Overview Water Resource Plan The Southern Delivery System Purpose and Need Delivery and storage of water supply Provide redundancy for ageing infrastructure Maximize existing assets (water rights)

  13. Proposed Southern Delivery System Option 2008 Draft EIS 2009 ROD and Construction starts 2012 Pumps & pipes 2012 Water treatment – Phase I 2014-2017 Jimmy Camp Reservoir 2020-2030 Williams Creek Res.

  14. Project Cost (2006 Dollars ) • Phase One Capital Cost: $593 Million • Pipeline, pump stations, 50 million gallons a day water treatment plant, and treated water pipelines • Future Phases Capital Cost: $440 Million • Reservoirs and water treatment plant expansions

  15. NEPA Process The National Environmental Policy Act (NEPA) requires federal agencies to integrate environmental values into their decision making processes by considering the environmental impacts of their proposed actions and reasonable alternatives to those actions. To meet this requirement, federal agencies prepare a detailed statement known as an Environmental Impact Statement (EIS). Environmental Protection Agency (EPA) reviews and comments on EISs prepared by other federal agencies, maintains a national filing system for all EISs, and assures that its own actions comply with NEPA. Major Milestones and Schedule • Resource Studies, 2006 • Alternatives Released, 2007 • Draft EIS for public comment, 1st Quarter 2008 • Record of Decision, 1st Quarter 2009

  16. Planned Environmental Impact Studies

  18. County 1041 Process • In 1974 the Colorado legislature adopted the Land Use Act in response to the “rapid growth and development of the state and the resulting demands on its land resources. • It was a first designed to • Protect land resources by some control over “projects of statewide interest” • Allocation resources among competing uses • Promulgate guidelines • Not prohibit

  19. SDS Summary • SDS is a cooperative regional project • Lowest cost alternative • Environmentally responsible • The Southern Delivery System will NOT: • take another community’s water • impact Pueblo’s Historic Arkansas Riverwalk • “dry up” the Arkansas River through Pueblo • “dry up” lower Arkansas Valley

  20. Summary • Water planning risks are significant Supply side Demand side Infrastructure • A Comprehensive water supply plan needs Diversity Flexibility • Project risks are significant Permitting: Federal and local Political opposition Environmental opposition Financial and rate impacts Water projects are EXPENSIVE!

  21. Outline Water System Overview Water Resource Plan The Southern Delivery System Challenges

  22. Challenges • Demand > Supply = need Growth in Colorado and the West Groundwater reliance Climate variability and change • Aging infrastructure • Regulatory Water quality

  23. Challenges Competing Uses Watershed & Forest Management

  24. Challenges: the biggest People!!!! • Engineering • Scientific • Business & Financial • Legal • Relationships & communications • Leaders!
