10 grains.
Softer than the rumor.
Cottonwood Heights publishes no hardness figure of its own. Jordan Valley Water Conservancy District, which supplies it, reports 170 mg/L — about 10 grains per gallon. That is hard water and it will scale, but it is at the mild end for the Salt Lake Valley, and it is roughly a third of what some softener companies will tell you to size for around here.
