The Minnesota American Council of Engineering Companies (ACEC) presented the Upper Sioux Community with an award for the Community’s Wastewater Treatment Improvements at the Council’s annual awards banquet on January 31.
The Upper Sioux Community (USC), or Pezihutazizi Oyate, is a federally recognized Native American tribe with lands located near Granite Falls, Minnesota. The USC contacted Bolton & Menk, Inc. to evaluate long-term wastewater treatment options. Based on goals of the Community, it was determined that the appropriate long-term solution was the implementation of a mechanical wastewater treatment facility utilizing Membrane Bio-Reactors technology. Membrane Bio-Reactors (MBRs) utilize an extended aeration activated sludge treatment process with membranes in the final aeration reactor. The selection of the Membrane Bio-Reactor technology will provide treatment that will result in a wastewater effluent that meets or exceeds all current and applicable water quality standards for the area. This selection reflects the USC’s goal of excellent stewardship of natural resources.
