Partnering with ReclamationPartnering with Reclamation
1. Equus Beds Groundwater Recharge Demonstration Project (1980’s)
High Plains Groundwater Demonstration Program ASR is feasible and suitable for full-scale
implementation
2. 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)
3. Reclamation sponsored City’s EIS
ROD issued January 2010 (18 months)
