West Water Treatment Plant <br /> CLIENT: CITY OF CHANHASSEN <br /> LOCATION: CHANHASSEN, MN <br /> DURATION: 2016 - 2018 <br /> WSB provided professional engineering services for <br /> the design and construction of a 9 million gallon <br /> per day water treatment plant.The West Plant was <br /> constructed at the south end of Manchester Road <br /> near the intersection of Lake Harrison Road and <br /> Galpin Boulevard.After WSB conducted multiple <br /> neighborhood meetings and received public input,the <br /> plant was designed with a prairie themed architecture <br /> and landscaping to fit into a residential neighborhood. <br /> Based on pilot plant testing and initial evaluations, <br /> the plant was designed to treat iron, manganese,and <br /> natural ammonia with pressure aeration, detention, <br /> concrete gravity filters,and breakpoint chlorination. <br /> The plant also includes a below grade clearwell,filter <br /> backwash tanks,and a backwash reclaim system. <br /> Chemical feed systems were designed for oxidation <br /> of iron and manganese,fluoridation, disinfection,and <br /> phosphate feed. <br /> The disinfection system was designed for the use of <br /> gas chlorine with 1-ton storage cylinders.A stormwater <br /> reuse system allows the city to recycle stormwater on <br /> site and use it for irrigating the landscaping around the <br /> plant and the adjacent boulevards located along Lake <br /> Harrison Road. KEY WSB STAFF: GREG JOHNSON, GREG GLUNZ <br /> This project included raw water mains constructed from <br /> the west well field to the treatment plant in preparation <br /> of the outlot located north of the treatment plant site for <br /> a future neighborhood park. <br /> A Proposal for Design,Bidding,and Construction Administration for a <br /> Water Treatment Plant for City of Lino Lakes Relative Experience,Qualifications,&References 125 <br />
