After WSB MN #26430 conducted multiple neighborhood meetings and received public input, the plant was WI #36036 designed with a prairie themed architecture and landscaping to fit into a residential IA #21765 neighborhood. Based on pilot plant testing and initial evaluations, the plant was ND #10078 designed with pressure aeration, detention, concrete gravity filters for treating iron, manganese, and natural ammonia that exist in the city's west well field. The Minnesota EDUCATION: Section of APWA nominated this project for the National APWA Environment Award. MS Civil Engineering University of Minnesota, 2002 Advanced Oxidation Process Water Treatment Plant I St. Anthony, MN CLIENT: ST. ANTHONY VILLAGE BS Civil Engineering, PROJECT DURATION: JUN 2015 - MAY 2018 University of Minnesota, Greg was the Project Manager and the Lead Process Engineer on this project. WSB 1994 provided professional engineering services to study, design, and provide construction services for a 3,500 gallon per minute (gpm) advanced oxidation process (AOP) water treatment plant to treat 1,4-Dioxane. This contaminant was detected in the groundwater aquifer that provides drinking water for the city's wells. Three UV units were installed inside a new masonry and precast concrete building constructed adjacent to the city's existing water treatment plant. The new building or WTP addition includes a chemical storage room for feeding hydrogen peroxide, an electrical room, and a piping gallery. The existing effluent piping from the existing greens and filters was routed into the new WTP addition, metered, and connected to the individual UV treatment units.
