MemoTo: Bradley P. MarksFrom: Christopher Ross, Brody Lawrence, Nichole EricksonSubject: Campus Stormwater Runoff SolutionDate: November 10, 20111. Design a system that will prevent the transport of pollutants into the Red Cedar River based on a 25-yr 1-hour storm.2. Criteria for Success:-Remove 90% of heavy metals, carcinogenic compounds, pesticides, nitrogen and phosphorus.-Limit budget to 20,000$-Reduce peak flow rate by 50%-Comply with the Clean Water Act3. Research Information Items-Michigan’s 25-year, 1-hour storm rainfall in inches per hour.-Types of Natural Filtration such as peat moss/macro algae.-How much pollution is previously in the drainage system?-Total water volume expected in an hour.-Area of the watershed within the central part of campus.-Find the map of previous storm systems.-Polluted vs. clean water standard values.4. Design Conceptual IdeasDesign #1: River Wetland Runoff (Stormwater Wetlands)-Create an artificial wetland using an enclosed anaerobic environment.
