An assessment of the existing network of interconnections between North Carolina’s 2,124 community water systems, for emergency and regular use, and their characteristics. This report also describes and applies a new methodology developed to determine the most geographically feasible options available for potential interconnections for water systems currently not on the receiving end of any interconnection. This GIS analysis takes into account the geographical challenges of transporting water, such as topology, environmental and infrastructure barriers, and determines the optimal route for potential interconnections between systems. The report includes detailed maps of existing and potential water system interconnections in each region of North Carolina in the appendix.
