Student Design Competition. Teams from the University of British Columbia (Vancouver) and the University of Colorado (Boulder) won this year’s top prizes. Photo courtesy of Oscar & Associates.

The competition, which showcased innovative design projects from 30 universities, recognizes outstanding solutions to local water quality issues in two categories: Water Environment and Wastewater. Successful teams evaluated various potential solutions to their issue of choice, performed thorough calculations and performance assessments, and recommended the most cost-effective interventions.

This year’s Student Design Competition sponsors included GDH Consulting (Tulsa, Okla.), Greeley and Hansen (Chicago), Black & Veatch (Overland Park, Kan.), and CDM Smith (Boston, Mass.). Representatives from sponsor organizations served as contest judges, joined by additional experts from the Metropolitan Water Reclamation District of Greater Chicago.

“The judges were thrilled about their choice of winners,” said Megan Livak, manager of WEF’s Students & Young Professionals Committee. “The success of the day definitely reflected the effort of the young professionals who spent a year organizing the event.”

 

Real-World Design Experience

Water Environment category judges lauded the UBC team for their project, which evaluated two potential solutions to improve management of runoff from aircraft de-icing fluid at nearby Vancouver International Airport. The airport does not currently have on-site treatment capabilities for de-icing fluid runoff, which contains the pollutant glycol, and spends an estimated $1 million each year disposing of used fluid.

The UBC team determined whether it would be more economical for the airport to construct wetlands that would accept and naturally treat the de-icing fluid runoff, or instead implement a glycol recovery system.

Calculating both up-front expenses and life-cycle operations and maintenance costs, the team determined that the constructed-wetlands approach would save the airport around $19 million over 30 years compared to the glycol recovery system while enhancing protections for nearby waterways.

The UBC team included Luthfi Subabio, James Craxton, Daniel Luo, Johnson Li, and faculty adviser Noboru Yonemitsu.

Other 2019 winners in the Water Environment category included Georgia Institute of Technology (Atlanta) in second place; Northeastern University (Boston, Mass.) in third place; and the University of Central Florida (Orlando) in fourth place.

In the Wastewater category, the UC team worked with the City of Gunnison (Colo.) Department of Public Works to plan water resource recovery facility (WRRF) renovations that will enable the utility to comply with future regulations. The WRRF requested solutions for the area’s chronic problems with inflow and infiltration, which result in diluted wastewater influent that prevents the utility from implementing enhanced nutrient removal technologies.

The UC team, which includes Powell Hinson, Rachel Knobbs, Lin Ye, Brandon DaSilva, Ryan Smith, and faculty adviser Angela Bielefeldt, developed a 50-year renovation plan that enables the utility to implement enhanced nutrient removal while also addressing infiltration and inflow and minimizing energy costs. The team’s winning design involves submerging existing mechanical aerators in oxidation ditches, creating a new anaerobic zone, installing dissolved oxygen probes, and adding variable frequency blowers to enable simultaneous nitrification/denitrification.

Also recognized in the Wastewater category were North Carolina State University (Raleigh) in second place; Utah State University (Logan) in third place; and the Milwaukee (Wis.) School of Engineering in fourth place.
