Western Intake Study A shared intake will be more efficient and likely to obtain regulatory approval than individual intakes for each Partner Feasibility Study will be complete in May 2014 Conceptual level study to evaluate the feasibility of a shared raw water intake for: Chatham, Durham, Pittsboro, OWASA Study Includes: Evaluation of three (3) alternatives: Review of Partnership options Development of a conceptual level permitting and a construction schedule for the Preferred Alternative

Each Partner will complete Jordan Lake allocation process Plan future infrastructure investments Western Intake Regional interconnections Continue to support regional collaboration
