Orem Water Hardness & Quality Report (2026)

Orem City Water is supplied in partnership with the Central Utah Water Conservancy District (CUWCD) and operates the Don A. Christiansen Regional Water Treatment Plant (DACRWTP). The utility draws 60% of supply from surface water sources including the Provo River and Jordanelle Reservoir, 25% from nine deep groundwater wells distributed throughout the city, and 15% from two mountain spring sources in Provo Canyon. All surface water undergoes filtration and disinfection at the DACRWTP, while groundwater and spring sources require no treatment before blending into the distribution system. In 2023, Orem produced over 7.9 million gallons of water.

Orem's water originates from the Provo River watershed and subterranean aquifers beneath the ancient Lake Bonneville bench, a geologically significant formation of the central Wasatch Front. Groundwater sources encounter mineral-rich Quaternary and Tertiary formations composed primarily of limestone and dolomite deposits. As precipitation percolates through these carbonate-rich rock layers over extended periods, it dissolves substantial quantities of calcium and magnesium ions, resulting in a hard water supply characteristic of the Wasatch Front region.

Orem's hard water creates noticeable scale buildup in water heaters, reducing energy efficiency and shortening equipment lifespan. Soap and detergent effectiveness is diminished, requiring higher product volumes for cleaning. Mineral deposits form on fixtures, glassware, and plumbing surfaces. Most residents benefit from installing a water softener, particularly for homes with electric water heaters or those concerned about appliance longevity and cleaning efficiency. Orem's drinking water meets all USEPA and State of Utah standards; the 2024 Consumer Confidence Report confirms rigorous filtration and disinfection at the DACRWTP, with groundwater and spring sources monitored for safety before distribution.
