Water Supply Status

Project Overview


Triangle J Council of Governments (TJCOG) received a grant in 2015 to improve drought response communications in the Triangle region from the new Duke Energy Water Resources Fund. By 2060, the Triangle region is expected to grow by 1.6 million people and will need an additional 95 million gallons per day of drinking water beyond current supplies. The region will also face increased water scarcity along with climate variability. TJCOG worked with local governments and water utilities across the Triangle to collaboratively develop common water supply metrics, consistent water use and water supply reporting, and best communication practices.


Project Deliverables

Three technical memos were produced outlining the results of this collaborative regional assessment: 

Water Utility Information and Procedures

Best Practices and Recommendations
Regional Drought Communication Frameworks


In addition, this water supply web page was developed to provide improved communication among water users, as well as accurate and timely information on water supply status for news media and others, especially during droughts. This project is one step in TJCOG's efforts to ensure reliable water supplies in the Triangle.


Water Supply in the Triangle Region

The Triangle Region relies on a wide diversity of water sources, spread across two river basins. Explore the map below to see some of the sources being used in our region, and which communities they serve.

Several utilities in the region do not publish water supply status information online.
