7 <br />Triangle Regional Water Supply Plan — Executive Summary <br />What has the Partnership Accomplished? <br />The first step was for JLP members to develop demand projections through 2060, and a key part of this <br />effort was engaging in a careful peer review of each other's demand projections. The Partners also <br />shared information about conservation and water use efficiency efforts, identified existing <br />interconnections and evaluated new interconnection opportunities. After determining future needs, the <br />Partners developed a pool of potential water supply source options, and coordinated with the NCDENR <br />Division of Water Resources (DWR) to use the combined Cape Fear -Neuse River Basin hydrologic model <br />to define and evaluate alternatives. The result is the mutually- supported Triangle Regional Water <br />Supply Plan for meeting the future water supply needs of the Triangle Region. <br />What are thu Region's Watl auph,_ Needs? <br />The region's existing and planned water supplies (Figure 2) are associated primarily with man -made <br />reservoirs, along with a few run -of -river withdrawals and supplemental quarry storage. The region does <br />not import water from outside the Neuse and Cape Fear River basins; though the Partners currently <br />have a combined net transfer of surface water from the Neuse basin to the Cape Fear basin. <br />i <br />_��— �-------- - - - - -- <br />___ <br />__ 1 <br />TriangleArea Raw Water Sources <br />+ <br />Q county aaa Bounda • Existing VJa rar Source <br />I <br />W.

Single dots sometimes <br />represent multiple sources that are geographically close (e.g., OWASA's reservoirs) and/or more than one <br />utility using the same source (e.g., Jordan Lake). The numbers by each source represent approximate yield <br />in MGD, but have been rounded to whole numbers in this graphic. Details of each source are provided in the <br />TRW SP. <br />3 <br />
