Wilmington, NC Water Source & Treatment
An educational overview of where Wilmington drinking water comes from, how it’s treated, and where to find the official annual water quality report.
Where Wilmington Water Comes From
Wilmington’s drinking water is supplied by the Cape Fear Public Utility Authority (CFPUA). The primary source of drinking water is the Cape Fear River, which provides raw surface water to the region.
Water is withdrawn from the river at CFPUA’s intake and transported to treatment facilities before being distributed to homes and businesses across Wilmington and surrounding areas.
How Wilmington Water Is Treated
Wilmington’s water is treated at CFPUA facilities including the Sweeney Water Treatment Plant and the Richardson Nanofiltration Plant.
The treatment process includes coagulation, filtration, disinfection, and advanced nanofiltration designed to remove contaminants such as organic compounds and PFAS chemicals associated with the Cape Fear River watershed. Water quality is continuously monitored to ensure compliance with state and federal standards.
