Seasonal shift to Jordan Valley water now in place

Herriman’s drinking water has now switched to its winter supply, which comes almost exclusively from the Jordan Valley Water Conservancy District (JVWCD). The City Council decided in 2024 to use JVWCD water during the lower-use winter months to help with water hardness and overall water quality.

Utah’s water is naturally hard, and Herriman’s local wells are often very hard, usually measuring between 25–60 grains per gallon (gpg). JVWCD water is much softer, generally measuring at 12–15 gpg. As a result, residents may notice fewer water spots and less mineral buildup on faucets, appliances, and dishes when the system uses JVWCD water. If you have a water softener, you may want to adjust its settings for softer water. Read your manufacturer’s manual for instructions for your softener.

During most of the year, Herriman uses a mix of local wells and JVWCD water. Local water is less expensive to produce, while JVWCD water costs about four times as much. Using JVWCD water mainly in the winter helps improve taste and appearance while still managing costs. As outdoor watering increases again in the spring, the system will resume using more local well water mixed with JVWCD water.

All water provided to residents meets state and federal drinking water standards. The main difference residents may notice at this time of year is how hard or soft the water feels and looks, not its safety.

Residents with questions about water hardness in their neighborhood may contact Water Quality and Conservation Coordinator Wil Szwarc at 801-446-5323 or wszwarc@herriman.gov. More information is available on the water quality webpage.
