Why are we studying stormwater in the Department of Civil Engineering at the University of Toledo?

Stormwater contains contaminants including trash and debris, solids, metals, nutrients, bacteria, and oil and grease.

Stormwater is often discharged untreated to rivers and streams through outfalls.

Green Stormwater Infrastructure at UT

Bioswale Planting

Green stormwater infrastructure was constructed at the University of Toledo in 2014 from USEPA GLRI through Lucas County SWIF Funds.  These projects include a tree filter located adjacent to the Law School and a bioswale below Savage Arena.  Both structures are located between parking lots and the Ottawa River.  UT students have been intimately involved in design, construction, and ongoing monitoring of these sites. Below is a location and copies of educational signage posted at each of these locations.

 Monitoring is an important aspect of green stormwater infrastructure since there is little data related to performance.  Data that exists is site specific. We have installed a weather station at the University of Toledo which collects real-time weather data including rainfall, windspeed, relative humidity, and temperature adjacent to the tree filter.  These measurements vary significantly with distance and are critical for accurate estimates of stormwater runoff. This data is publicly available online.
