In 1993, the city of Wichita adopted the Wichita Integrated Local Water Supply (ILWS) plan, which presented possibilities to help the city meet water supply demand through year 2050. The ILWS included the development of an ASR program to support plan goals and to recharge the heavily used and significantly depleted Equus Beds aquifer. In 2001, Wichita implemented their ASR program through a 4-phase construction plan. The objective of this plan, currently in phase 2 (as of 2011), is to achieve 100 million gallons per day storage capacity (Sophocleous, 2012). 


  • 6 ASR wells installed during Phase 2
  • 26 additional municipal wells injecting water into the Equus Beds aquifer
  • The project is expected to add 100,000+ acre-ft of water to the aquifer over a 10-15 year timespan (deSilva and Ary, 2011)
  • Injection water obtained from Little Arkansas River
  • ASR used to create a barrier to prevent saltwater contamination; Equus Beds aquifer prone to salt water plumes due to vintage industrial developments
  • Phase 1 returned 900 MG to the aquifer at a cost of $27 million (Wichita, 2012)
