This scope of services was developed <br />after several meetings and discussions with Michele McPherson, Director of Planning, relative to the <br />comprehensive plan update, and Gary Leirmoe, Chief Operator of the WWTP. The scope of services <br />has been divided into five main parts with several of these having sub-parts identified underneath <br />them. The scope of services is as follows: <br /> <br />Determine Sanitary Sewer Capacity <br /> <br />Determine the available treatment capacity at the current WWTP, assuming a <br />small amount of land acquisition from Great River Energy is possible. <br /> <br />· Review and analyze the ultimate WWTP sewer capacity based on design <br /> calculations and conceptual drawings from the 1995 WWTP expansion. <br />· Analyze current treatment technology and project future additional treatment <br /> processes that will be needed. <br />· Discussions with Great River Energy to determine amount of land possible for <br /> additional acquisition to WWTP site. <br />· Prepare analysis of ultimate WWTP capacity and develop schematic of current <br /> WWTP facility with future treatment processes. <br /> <br />B. Determine ultimate wastewater flow from the current Urban Service Area. <br /> <br />· Identify current areas developed in various land uses relative to the current <br /> average WWTP daily sewage flow. <br />· Identify areas that are currently platted but not built on and project estimated <br /> future sewage flow based on land use. <br /> <br />Ltr-011204-Klaers.doc <br />2550 University Avenue West · Suite 400N ° St. Paul, MN 55114 ° 651/644-4389 fax 651/644-9446 toll free 888/368-4389 <br /> <br /> <br />
