asr a win win solution
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
impediments to asr program
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
partnering with reclamation
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)
external funding support
