The bioswales at Purdue Discovery Park were installed during the sixth phase of landscaping work, completed in 2009. Located on the west side of Mann Hall, the bioswales slow and/or eliminate excess stormwater into the sewage system, help maintain the area’s hydrological profile, and clean the water off pollutants. The water is receded from the grassy mall area into the bioswale, and it then meanders slowly downhill before it goes into the drain, soaking into the ground along the way. The bioswales here also have plenty of native plants and boulders, adding to their aesthetic appeal. Office of University Sustainability
