The City of Sanford's goal has been to produce the safest and highest quality drinking water for all its customers. We are proud of our history of quality service. To maintain our commitment to you, our analysts routinely collect and test water samples every step of the way - from the source waters right to your home - checking purity and identifying potential problems.

Facility Standards

Our treatment plants are constantly maintained, evaluated, and upgraded to stay abreast of advancements in technology, health science and government regulations. Our water quality lab is the heart of our quality assurance program.

Staffed by highly trained technicians, the state-certified laboratory has the latest, most sophisticated instruments, and can measure substances down to one part in a billion. Through foresight and planning, efficiency in operations, and focus on excellence in customer service, we will provide you the best quality drinking water at an economical price well into the 21st century.

Water Source

The City of Sanford's customers are fortunate because we enjoy an abundant water supply from a single surface water source, the Cape Fear River. The Water Filtration Facility is located in close proximity to the headwaters of the Cape Fear River formed from the convergence of the Deep, Haw, and Rocky Rivers.

Regional Supplier

The Water Filtration Facility is a regional supplier of drinking water to the City of Sanford, the Town of Broadway, Lee County, and sections of Chatham County. The treatment capacity is twelve million gallons per day, averaging seven million gallons per day. The treatment facility produces over two billion gallons of clean drinking water every year delivered directly to you, our customers.

Annual Water Treatment Process Change

The City of Sanford normally uses a combination of ammonia and chlorine to disinfect its drinking water. However, the N.C. Division of Water Resources recommends us to stop using ammonia for 30 days to help maintain our high quality of water.

The City stops adding ammonia to its water treatment process on March 1 of each year. It resumes adding ammonia to the disinfection process on April 1 of each year. Learn more here.
