Over the last two <br />years, these various entities have collaborated to create consistent standards, terminology, <br />projection methodologies, and options as the upcoming requests for long term water needs are <br />developed. Although the demands and supplies of Jordan Lake and other water supplies have <br />been comprehensively evaluated, the applications are associated but reviewed independently <br />with each local government /utility by DENR. <br />Various aspects of water supply modeling are employed including how to transmit water from <br />the supply (i.e. lake or reservoir, etc.) to the demand area (i.e. populations and businesses). <br />Therein lies the purpose of this abstract item. Hazen and Sawyer, the Jordan Lake <br />Partnership's engineering consultant, has proposed Phase II of the Jordan Lake <br />Interconnection Study which will analyze existing pipe infrastructure and necessary pipe sizes to <br />accommodate a regional system of water transmission among the various applicants. This is <br />necessary since water supply intakes on Jordan Lake are limited so future water transmission <br />will have to be `wheeled' around different `shared' pipe networks. <br />Orange County presently has Level II (reserve) raw water allocation of one million gallons per <br />day (mgd) and will likely be asking for a similar but additional three mgd to support the <br />development needs of the three economic development districts (EDDs) —Eno (partnership with <br />
