Herriman water
Herriman City's tap water meets all Environmental Protection Agency (EPA) and Utah Division of Drinking Water standards, with no violations reported in the 2025 Water Quality Report. The city blends its own wells and a spring with surface water from Jordan Valley Water Conservancy District and Bluffdale City. Because much of the local groundwater is mineral-rich, Herriman is known for hard water.

What helps
What we would do about it.
If you want crisp, great-tasting drinking water on top of an already-compliant supply, a countertop or under-sink water ionizer can raise the pH and improve taste, while a whole-home salt-free conditioner can help reduce the scale that comes with Herriman's hard water.
