The Madison Metropolitan Sewerage District (MMSD) manages regional wastewater service for the Madison, Wisconsin area, providing wastewater collection and treatment for 43 municipal customers including cities, villages, and utility and sanitary districts. In 2012, the plant made a goal to reduce energy consumption.

An evaluation of the mixing system was conducted in the biological selector basins. It revealed the potential for significant energy savings, due to already installed process improvements and repositioning the mixers for more efficient production of bulk-flow velocity.
