Kaysville Water Hardness & Quality Report (2026)

Kaysville City Public Works manages the water utility, purchasing all treated water from the Weber Basin Water Conservancy District (WBWCD). WBWCD draws raw water from the Weber River and tributaries including Chalk Creek and Oakley Creek along the Wasatch Front in Davis and Weber Counties, Utah. Treatment is carried out at WBWCD facilities including the Riverdale Treatment Plant, with the finished supply then delivered to Kaysville City's distribution mains serving approximately 35,000 residents in Davis County.

The Weber River watershed spans the southern Wasatch Range, with headwaters in the Uinta Mountains transitioning to valley floors. The underlying geology features Paleozoic limestone and dolomite of the Oquirrh Group, alongside Quaternary alluvium and lakebed deposits from ancient Lake Bonneville. These carbonate-rich formations dissolve readily, contributing elevated concentrations of dissolved calcium and magnesium to the water supply and yielding a characteristically hard character prone to scale formation without mitigation.

With a hardness of 222.56 mg/L, Kaysville's water causes significant limescale buildup in pipes, water heaters, dishwashers, and washing machines, reducing energy efficiency and shortening appliance lifespan. Fixtures accumulate white deposits, soap lathers poorly, and laundry can feel stiff. A water softener sized to household usage is strongly recommended; regular vinegar descaling of fixtures and low-flow aerators help minimize deposits in the interim. Treatment by WBWCD includes coagulation, filtration, chloramination, and fluoridation, with pH typically maintained at 7.5–8.5 and lead and copper held below action levels. No PFAS exceedances have been noted in recent Consumer Confidence Reports, and arsenic from natural sources is monitored and confirmed below 10 ppb.
