Triangle Regional Water Supply Plan — Executive Summary What are the Key Conclusions of the Plan? • The Partners' current total water supply of 199 million gallons per day (MGD) is projected to meet their combined needs through approximately 2030. • An additional 95 MGD of supply is needed to meet 2060 water supply needs (total 294 MGD). • The 2060 demands can be met in an environmentally and economically sound manner through a combination of: o 36.4MGD: Allocation of most of the remaining Jordan Lake water supply storage (Apex, Cary, Chatham County, Durham, Orange County, Hillsborough, Pittsboro); 0 20.6- 22.6MGD: Expansion of existing reservoirs, off - stream quarry storage, and run -of- river withdrawals (Hillsborough, Orange County, OWASA, Pittsboro, Sanford); and 0 41.1 MGD: Development of a combination —still to be determined —of new or expanded sources including reallocation from Falls Lake, a new intake in the Neuse River, off - stream quarry storage, and /or a new reservoir in eastern Wake County (Raleigh). • Implementation of water use efficiency and conservation practices and expanded use of reclaimed water will continue to be essential strategies for meeting the region's future water needs. • Hydrologic modeling has shown that the Triangle's water needs can be met without compromising the ability of downstream communities to meet their own water supply needs. • The region's ability to meet projected water demands in 2060 may be compromised if any of the TRWSP's recommended future water supply sources are not implemented as planned. Why was the Partnership Formed The Partners elected to be proactive in identifying potential water shortfalls and mutually acceptable and beneficial solutions for meeting future needs. The region experienced two historic droughts in 2002 and 2007 -2008. Regional planning and collaboration — developing solutions on a geographic scale larger than individual water suppliers — will increase the resilience of our water supply under similar extreme conditions. In addition, the Partners wanted to use hydrologic modeling to confirm that other upstream and downstream water needs within the Cape Fear and Neuse River Basins would not be impacted by a proposed strategy that met the needs of the Triangle. The challenges associated with utility management including increasing costs, greater regulatory requirements and increasing drought vulnerability can be more successfully met through inter -local collaboration in facility planning, design, construction, operation and management. The Partners, in various combinations, are engaged in joint projects including increasing the number and size of interconnections between water supply systems and consolidating utility systems through merger agreements. Some efforts include water supply planning over the entire hydrologic cycle where water, wastewater and stormwater service delivery are integrated to protect watersheds and improve response during drought or other water shortage conditions. The JLP was formed to complement these efforts, continuing to better prepare the Triangle Region to address water shortages on a regional basis.
