Nies speaks on the potential of indirect water reuse at IWEA

EEE Professor Larry Nies presents during the 2017 Indiana Water Environment Association (IWEA) annual conference.
Environmental and Ecological Engineering (EEE) Professor Larry Nies recently delivered a presentation entitled “Watershed Scale Management of Water Resources: Finding Answers in Large Heterogeneous Data Sets,” as part of the Indiana Water Environment Association (IWEA) annual conference.

IWEA is an organization dedicated to preserving and protecting Indiana’s waterways through education, and Nies’ talk did simply that by focusing on the untapped potential of indirect water reuse.

Nies along with EEE professor Chad Jafvert and Ph.D. candidate Julia Wiener, studied the Wabash River Watershed and collected data for water extraction, use, discharge, and river flow. This data was then used to determine water use and reuse levels.

During the low flow months of July-October, permitted point source discharges into the Wabash River basin contributed 80 to 120% of the stream flow. These results indicate that the fraction of use and reuse is substantial at the watershed scale.
