  1. Equus Beds ASR ProgramA Case Study in Success Texas Innovative Water 2010 Seminar October 11, 2010

  2. Outline • Concept • Purpose and Need • Planning and Development • Funding • Phase II Program • Keys to Success

  3. Source of Recharge Water • Above Base Flow Conditions • Expect to Recharge 120 days/year • Spring & Early Fall • Little Arkansas River • High Turbidity (5 to 2,000 NTU) • Atrazine (<1 to 50 mg/L)

  4. Min. Flow Rate for Phase II Intake (30 MGD) 7 to 10 Days Typical Storm Event

  5. Sources of Supply Burrton Equus Beds Well Field Cheney Reservoir Arkansas River Little Arkansas River Local Well Field Bentley Well Field Wichita Wichita Water System: 186 mi2 Service Area 425,000+ Served

  6. Meet Water Supply Demands Max Day Demands (no additional conservation) Max Day Demands (with additional conservation) Total Supply – 130.5 mgd Bentley Wellfield – 11.5 mgd Local Wellfield – 7 mgd Equus Beds Wellfield – 40 mgd Cheney Reservoir – 72 mgd Source: Aquifer Storage & Recovery Program Review, Water Supply Plan (HDR, 2010)

  7. >40 feet of water-level decline since 1950 Reverse Water-Level Declines • Groundwater pumping has created a depression • 65 Bgal of storage capacity available (return to 1940 water levels)

  8. City Wells City Wells Protect Water Quality 1998 2006

  9. Planning & Development • Integrated Local Water Supply (ILWS) Plan • Evaluated 27 Alternatives • Approved 1993 • Meet 2050 Water Demands • Principal Component is a 100-MGD ASR Program

  10. 120 Miles Imported Water Alternative • Milford Reservoir Alternative Milford Reservoir 15 Cities from Wichita to Chapman Wichita

  11. ASR: A Win-Win Solution • Reliable & Sustainable Water Source • Preserve Equus Beds Water Quality • No Requirements to Curtail Irrigation • Lower Pumping Costs • Augments Low Flows • Less Land Required • Avoid Evaporation Losses

  12. Impediments to ASR Program • 1st ASR Project in Kansas • No Regulations to Administer • No Proof ASR would not Contaminate the Aquifer • Poor Image of City in Project Area

  13. Partnering with Reclamation • Equus Beds Groundwater Recharge Demonstration Project (1980’s) • High Plains Groundwater Demonstration Program • ASR is feasible and suitable for full-scale implementation • Congressman Tihart (KS) introduced bill to authorize Reclamation’s funding participation • P.L. 109-299 passed in 2006 • 25% up to $30M ($41M in today’s $s) • Reclamation sponsored City’s EIS • ROD issued January 2010 (18 months)

  14. External Funding / Support • U. S. Bureau of Reclamation • Special Authorization • Cooperative Agreement • State of Kansas • Kansas Water Office • Up to $1M/year • U. S. Geological Survey • Data Collection • Groundwater Monitoring

  15. Phased Implementation

  16. ASR Phase II Program • 30-MGD Capacity • ASR Facilities • River Intake • Treatment Plant • 31 ASR Wells • Recharge Basin • 40+ miles of Pipelines • Power lines & substation • Surge Tanks

  17. ASR Phase II Facilities • ASR Well

  18. ASR Phase II Facilities • River Intake

  19. Clearwell AOP Building Membrane Building ASR Phase II Facilities • Surface Water Treatment Plant

  20. “Index Cell” (4 mi2) Groundwater Model Boundary Recharge Accounting Source: USGS, 2010

  21. Keys to Success • Partnerships • Phased Implementation • Favorable Administration and Accounting Framework • Nearby Recharge Water Source • Strong Leadership

  22.
