Draper Water Hardness & Quality Report (2026)

Draper, Utah, in Salt Lake County at the southern end of the Salt Lake Valley at the base of the Wasatch Range — a fast-growing affluent south Salt Lake Valley community, a major Utah tech corridor (Adobe Systems, eBay, and numerous Silicon Slopes companies have offices in Draper), gateway to the Draper Temple and Point of the Mountain (a premier hang gliding and paragliding site), and one of Utah's most rapidly developing communities — draws its municipal water supply from the Jordan Valley Water Conservancy District (JVWCD) surface supplies and local groundwater via the City of Draper Water Division. Water hardness in Draper measures 347.5 mg/L — classified as very hard.

Draper's very hard supply reflects the extreme Wasatch Front calcareous geology. Draper's supply sources include: Bells Canyon Reservoir water (Little Cottonwood Creek — draining the calcareous Precambrian Big Cottonwood Formation limestone and the Cambrian Tintic Quartzite and Ophir Formation calcareous zone of the central Wasatch Range); JVWCD Jordan River and Utah Lake supply (the Utah Valley calcareous watershed — surrounded by Cambrian–Devonian calcareous limestone throughout the Wasatch and Oquirrh Range); and the Draper area alluvial aquifer (deep calcareous Quaternary alluvial fan from the Oquirrh Mountains calcareous Pennsylvanian Oquirrh Formation — cyclic calcareous limestone–sandstone). The combined highly calcareous Wasatch Front limestone terrain produces the very hard 347.5 mg/L.

At 347.5 mg/L, Draper residents face severe hard water challenges. Scale deposits form very rapidly on all fixtures and appliances — weekly descaling and appliance protection measures are strongly recommended. City of Draper Water Division consistently delivers water meeting all Utah DDW and EPA Safe Drinking Water Act requirements.
