Civil 5 - CSO Residential Stormwater Treatment
Student Team: Cody Meckes, Roberto Silva, Julia Pavicic, Eric Spurbeck
Advisor: Bob Turner
Sponsoring Organization: City of Spokane
Liaison: Bob Turner
Our goal is to provide comprehensive engineering efforts related to the development of sustainable technologies to reduce the stormwater contribution to sewer flows by treating runoff at residential sites in Spokane, Washington. Currently, Spokane relies on an outdated combined sewer system that has been rendered illegal by extensions of the Clean Water Act of 1972. The project entailed researching and testing low impact development (LID) ideas to reduce stormwater runoff at the site. We researched rain gardens, bio infiltration trenches, porous material, and dispersion as alternative solutions. The team created conceptual designs, decision matrices, and a cost analysis of the specified alternatives. The City of Spokane will use these deliverables to evaluate stormwater options throughout the city.
