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

Water System
  • Serves 412,800 people with about
  • 81,000 acre-feet/year or 26.3 Billion
    Gallons/year
  • Growing _at_ 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

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

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

10
Water Resource Plan
  • 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

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

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 communitys water
  • impact Pueblos 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!

Return Flows
It is estimated that by 2046 the non-native water
in FC will increase to 1/3 of creek flow (over
1990-2006 was 17).

Sediment Loading
  • Sediment loads increase with increased flow rates
  • Significantly less sediment carried at base flows
  • 15 tons/day of suspended sediment is carried for
    transmountain return flow rates (35 cfs, 2006
    reusable return flow)
  • 400 tons/day of suspended sediment is carried for
    average yearly flow rates (165 cfs)
  • 200,000 tons/day of suspended sediment is carried
    during a channel forming flow rate (1.4 year
    rainfall event, 2900 cfs)
