Davidson Water Hardness & Quality Report (2026)

Davidson Water, Inc. draws its supply from the Yadkin River, a major waterway originating in the Blue Ridge Mountains and flowing through the Piedmont region of North Carolina. The Koontz Road water treatment plant, located near Highway 64 West in Lexington, NC, processes this surface water for an estimated 148,000 residents across Davidson County and surrounding areas, including Lexington and Davidson. Conventional treatment methods such as coagulation, sedimentation, filtration, and disinfection are employed to ensure the water meets safety standards.

The Yadkin River watershed, spanning over 7,000 square miles, passes through areas dominated by ancient metamorphic rocks like feldspathic gneiss and mica schist, characteristic of the Carolina Slate Belt in the Piedmont. These geological formations contain very few sedimentary limestone layers. This specific rock composition means there are naturally low levels of dissolved calcium and magnesium, which are the primary minerals contributing to water hardness, resulting in the very soft water supplied to consumers.

Because the water is very soft, homeowners will notice that soap lathers easily, requiring less detergent and soap. Scale buildup on pipes, fixtures, and appliances like water heaters and dishwashers is significantly minimized, which can extend their lifespan and reduce maintenance. While a water softener isn't generally recommended due to the already low mineral content, it's always wise to monitor your plumbing for potential corrosion, a slight risk with soft water supplies. Davidson Water's tap water consistently meets all federal safety standards, with lead and copper levels well below action limits.
