Improving water quality with water storage mixing systems

Project ID: 6988
Principal Investigator: Merlynn Bender
Research Topic: Water Quality
Funded Fiscal Years: 2015 and 2017
Keywords: None

Research Question

Can water storage mixing systems help improve various water quality issues, including but not limited to algal blooms, dissolved oxygen, metals, and turbidity?

Need and Benefit

Water storage mixing systems create circulation using a downdraft pump to mix the water column from the top down for purposes of improving various water quality issues, including but not limited to algal blooms, dissolved oxygen, metals, and turbidity. The proposed research would include:
1) A review of relevant current literature regarding top down water storage mixers, including but not limited to the Australian WEARS system. Review would include the recently published report, Wagner, K. W. 2015. Oxygenation and Circulation to Aid Water Supply Reservoir Management, Report #4222c, Water Research Foundation, Denver, CO.
2) Interview current users and review monitoring data from operating top down water storage mixing systems, focusing on the western U.S. systems in place.
3) A report that indicates validity and potential benefits to Reclamation and asks the question, is this a new technology that would be applicable to addressing clarity issues in Grand Lake and valid for water quality issues in other Reclamation facilities?
