This report is a high level feasibility study reviewing the potential for combining municipal potable water <br />systems in the northeast Twin Cities metropolitan area. Six cities requested that the Metropolitan <br />Council investigate the costs and benefits of combining the construction and operation of their potable <br />water systems. The six -city coalition is an existing collaborative effort between the cities of Centerville, <br />Circle Pines, Columbus, Hugo, Lexington and Lino Lakes. The purpose of this coalition is to identify <br />opportunities for efficiency and cost savings in the public water system services they provide. The <br />geographic planning area is shown in Figure Al (located in Appendix A). <br />This concept aligns with the Metropolitan Council's goal to ensure sustainable water supply for current <br />and future generations of the Twin Cities metropolitan area. The purpose of this study is to support <br />sustainable water supply planning for the northeast metropolitan area. <br />The Metropolitan Council authorized Barr Engineering to conduct a preliminary investigation of a <br />combined or joint water utility. The three system configurations considered are: <br />Joint Utility Jointly constructed, owned and operated supply, <br />Option 1: storage and treatment system. Independently <br />constructed, owned and operated distribution <br />systems. <br />Joint Utility Jointly constructed, owned and operated supply, <br />Option 2: storage, treatment and distribution system. <br />Independent Make no changes. Operate as independent <br />Utilities utilities. <br />Option 3: <br />This study examines in a preliminary way the effects of a joint system on the existing and future <br />drinking water systems. This report identifies the preliminary advantages and disadvantages of <br />combining systems, how the collaborative effort might be managed, and possible financial impacts to <br />each city. This study includes the gathering of existing and future water utility data, development of <br />feasibility and cost/benefit analyses, and recommendations for future work. <br />1.1 Report Organization <br />The remainder of the report is organized into the following sections: <br />• <br />Section 2.0 <br />Executive Summary <br />• <br />Section 3.0 <br />Background and Purpose <br />• <br />Section 4.0 <br />Water System Performance Criteria <br />• <br />Section 5.0 <br />Water Demand and Supply <br />• <br />Section 6.0 <br />Water Storage <br />• <br />Section 7.0 <br />Water Distribution <br />• <br />Section 8.0 <br />System Operations and Maintenance <br />• <br />Section 9.0 <br />Evaluation of Development Options 1-3 <br />• <br />Section 10.0 <br />Recommendations <br />Joint Water utility Feasibility Study 6 <br />
