Highland Water Hardness & Quality Report (2026)

Highland City Water Department serves approximately 20,000 residents in Highland City, Utah County, Utah, within the Provo-Orem metropolitan area. The utility draws from a mix of local groundwater wells along the Bull River and imported surface water from the Provo River watershed, treated at regional facilities like the Provo Water Treatment Plant. No dedicated Highland treatment plant is specified, but water is chlorinated and fluoridated per state standards before distribution through the municipal system to households across the city.

The supply originates in the Utah Valley watershed, encompassing the Wasatch Front mountains and Provo River drainage. Underlying geology features thick sedimentary layers of limestone, dolomite, and evaporites from the Jurassic Arapien Formation and Cretaceous-age units, which form confined aquifers. These carbonate and sulfate-rich rocks naturally mineralize the water, resulting in a very hard supply with elevated calcium and magnesium from prolonged contact with limestone bedrock and gypsum seams. Alluvial aquifers in the Utah Valley basin further contribute dissolved minerals from limestone weathering.

Very hard water in Highland leads to significant scale buildup in pipes, water heaters, dishwashers, and washing machines, reducing efficiency and lifespan. White deposits on fixtures and reduced soap lathering are common. Regular vinegar descaling, installing sediment filters, and annual appliance flushes help mitigate issues. A water softener is strongly recommended for all households. Water quality meets EPA standards with pH typically 7.5–8.5; the utility complies with lead and copper rules under the LCR. Treatment includes chlorination, fluoridation, and basic filtration; annual Consumer Confidence Reports confirm no violations for regulated parameters.
