Wichita Aquifer Storage & Recovery Phase II

Client: City of Wichita
Completion Date: September 2011
Location: Wichita, Kan.

Summary

Burns & McDonnell teamed with Alberici Constructors Inc. and CAS Construction as ABC Partners to design and construct Phase II of the City of Wichita's Aquifer Storage and Recovery (ASR) project. ASR is a part of the larger Integrated Local Water Supply project, on which the City of Wichita and Burns & McDonnell have been collaborating for nearly 15 years.

The design-build team developed a project approach based on a 30 percent design proposal and cost estimate provided by the city. The team developed conceptual plans and construction schedules based on value engineering and optimum construction methods that resulted in a lower overall projected cost. The combined effort by the team provided a lower facility cost from an estimated $104 million to $74 million at bid day and provided increased future expansion capabilities for the site.

For Phase II, Burns & McDonnell was responsible for the design of the surface water treatment plant (SWTP) and river intake on the Little Arkansas River. The major water treatment process associated with the project included:

  • 30 million gallon per day (MGD) submerged membrane filtration
  • Ozone/hydrogen peroxide advanced oxidation
  • Ground storage
  • High-service pumping
  • Residuals handling

The river intake site included the:

  • Intake pumping structure
  • Sedimentation basin
  • Intermediate pumping station

The project has earned numerous accolades, including:

  • DBIA Mid-America Regional Award
  • 2015 National Recognition Award from the American Council of Engineering Companies (ACEC)
  • 2015 Engineering Excellence Award from ACEC of Kansas
