Clemmons Water Hardness & Quality Report (2026)

Clemmons, North Carolina, receives its drinking water from the City of Winston-Salem Utilities Division, serving Forsyth County and surrounding areas including Davie County. Primary sources are surface water from the Yadkin River watershed, including Salem Lake and the W.S. Kerr Scott Reservoir, treated at the R.C. Hanes Water Filtration Plant and the E.A. Morris Water Filtration Plant. Groundwater from Piedmont crystalline-rock aquifers, monitored by the North Carolina Department of Environmental Quality, supplements the supply. The system serves over 250,000 customers across a 350-square-mile area.

The Yadkin-Pee Dee River watershed drains the Piedmont physiographic province, underlain by ancient crystalline rocks of the Blue Ridge and Piedmont provinces — metamorphosed volcanic and sedimentary rocks from the Precambrian era, intruded by granitic plutons. Fractured bedrock aquifers yield groundwater with low mineralisation, as the low solubility of silicate minerals — gneiss, schist, and granite — limits calcium and magnesium dissolution. Surface runoff from forested and agricultural lands picks up minimal dissolved solids, imparting a soft character to the blended supply.

Soft water in Clemmons means negligible scale buildup in pipes, water heaters, dishwashers, and washing machines — appliances maintain high efficiency without mineral deposits reducing flow or heating performance. No water softener is needed; soft water minimizes soap usage and spotting on glassware, with routine maintenance focused on sediment filters rather than descaling. Winston-Salem's 2024 report confirms low manganese (average 0.003 ppm) and pH meeting EPA standards; the utility complies with lead and copper rules through corrosion control, and treatment includes coagulation, sedimentation, filtration, and chloramination.
