Feasibility study <br />East Cherry Creek Valley Pipeline Capacity Acquisition <br />South Metro Water Supply Authority <br />Introduction and Need for Project <br />The South Metro Water Supply Authority (SMWSA) is composed of 13 independent water <br />providers that serve communities located to the south of Denver, Colorado. Most of the <br />providers have experience significant growth over the last decade and have been activity seeking <br />a sustainable/renewable water supply. The members of SMWSA have worked diligently to both <br />identify new supplies and to look for opportunities to share resources and infrastructure. <br />Currently, the members rely heavily on the bedrock groundwater aquifer to supply the areas <br />municipal and industrial (M&I) needs. The groundwater in the area does not have sufficient <br />natural recharge to match withdrawal rates and has therefore been commonly referred to as non- <br />renewable resource. <br />While the groundwater has provided sufficient, cost-effective means to meet current demands, <br />continued use of groundwater to meet anticipated future needs without additional renewable <br />water supply sources will/has resulted in diminished well yields and raises sustainability issues. <br />The proposed project will allow four members of SMWSA (Arapahoe County Water and <br />Wastewater Authority (ACWWA), Meridian Metropolitan District, Pinery Water and Waste <br />Water District, and Stonegate Village Metropolitan District) to acquire capacity in the East <br />Cherry Creek Valley (ECCV) Northern Supply Pipeline (Note: ECCV also has a western supply <br />line which is not currently part of this project but may become part of an overall supply plan). <br />The remaining members of the SMWSA will be obtaining their own financing or do not need <br />capacity in the water supply lines at this time <br />Funds from the loan will allow the 4 SMWSA participants to purchase capacity in the ECCV <br />Northern Pipeline which will aid the participants in accessing and conveying renewable water <br />supplies, recapturing consumable return flows, and increase operational flexibility. The <br />acquisition of pipeline capacity will allow the participants to take an important step in fulfillment <br />of the SMWSA, Regional Water Master Plan, June 2007. <br />The ECCV Northern and Western Pipelines were constructed in 2006. The Northern line is a 48 <br />inch steel pipe [47 Million Gallons/Day (MGD) capacity], approximately 31 miles in length, and <br />extends from approximately Barr Lake to ECCV's service area (located to the east of Cherry <br />Creek Reservoir). The Western line (also known as the Willows line) varies between 42 and 54 <br />inches of steel pipe, approximately 16.7 miles in length, and runs from approximately C470 and <br />Colorado Boulevard to ECCV's service areas. <br />Project Area Description <br />The SMWSA member service areas and/or the ECCV pipeline include Adams, Denver, <br />Arapahoe, and Douglas Counties. See Figure 1 for more detail. The area is highly urbanized, <br />moderate to high income with mixed residential, commercial and light industrial development. <br />There are over 1.5 million residents in the four counties; however SMWSA members serve only <br />a portion of these counties population. Prominent surface water features include Chatfield <br />4 <br />
