Proposed Project Team and Experience <br /> The Shakopee Mdewakanton Sioux Community has an on-going commitment to protect the <br /> environment.As part of this commitment,the wastewater facility is design with a green roof <br /> system. Green roof design utilizes perennial plantings to create a green space on the roof of the <br /> facility,thus reducing storm water runoff for the building and creating an aesthetically appealing <br /> and energy efficient roof. The wastewater facility was on-line in August 2006. <br /> Wastewater Treatment Plant, Paynesville, MN (2012) <br /> Contact: Ron Mergen, Public Works Director,320-243-3714 <br /> Bolton&Menk, Inc. was retained by the City of Paynesville to prepare a Wastewater Facility <br /> Plan. Because of more stringent limits and a large industrial wastewater organic loading,the most <br /> cost-effective treatment alternative is to convert an aerated pond system to extended aeration <br /> activated sludge treatment facility. Existing infrastructure, including 240-acres of stabilization <br /> ponds and approximately 1,200-acres of spray irrigation fields,will continue to be used for final <br /> polishing and final disposal. Bolton &Menk was hired to design the recommended wastewater <br /> treatment improvements.The extended aeration facility included the following major items: <br /> improvements to the existing lift station;modification of an existing aerated pond; construction of <br /> a new secondary clarifier; construction of new aerobic biosolids treatment and storage facilities; <br /> construction of biosolids handling reed beds and construction of a new blower/control building. <br /> The City of Paynesville is in the process of securing a Beneficial Use of Wastewater Grant <br /> administrated by the Minnesota Pollution Control Agency due to the treatment and spray irrigation <br /> improvements associated with this project. <br /> Wastewater Treatment Facility, Rahr Malting Company, Shakopee, MN <br /> (2008) <br /> Contact: Dale Lundquist, Manager of Engineering/Process Design,952-496-7023 <br /> Bolton&Menk, Inc. along with the Rice Lake Construction Group have completed three Design/ <br /> Build projects for Rahr Malting Company. Rahr Malting has a malt processing facility located <br /> in Shakopee, Minnesota. Based on financial analysis,the Rahr Malting Company determined it <br /> would be more cost effective to treat and discharge their process wastewater rather than continue <br /> to use the Metropolitan Waste Treatment Facility. <br /> The first project was completed in 1998. The project consisted of a <br /> new activated sludge (SBR)wastewater treatment system. The range <br /> and peak design are 0.65 and 1.5 mgd respectively. <br /> The second project, completed in 2005,was the addition of a <br /> dewaterin facility. The project included the installation of a 2-meter <br /> g Y P J <br /> belt filter press and dewatered sludge conveyance system including an <br /> indexing conveyor to equally load the dewatered sludge into a semi- <br /> u trailer. <br /> The third project, completed in 2008,was the expansion of the process wastewater treatment <br /> facility to treat an average daily flow of 2.08 mgd with a peak treatment capacity of 3.0 mgd. The <br /> treatment expansion was an activated sludge (MBR)wastewater treatment system. The average <br /> and peak design process flows from the MBR facility are 1.5 and 2.25 mgd respectively. <br /> Wastewater Treatment Facility Improvements I City of Elk River, Minnesota 9 <br />
