Cottonwood Heights sits at the mouth of Big and Little Cottonwood canyons, a quick drive from our Salt Lake City office, just across I-215. A lot of the valley's drinking water starts right here, in the canyons above the city.
Around Cottonwood Heights
Cottonwood Heights calls itself the "City between the canyons," and the name fits. Much of its housing covers the high ridge between Big Cottonwood and Little Cottonwood creeks, with I-215 along the north edge of the city and the canyon roads, State Routes 190 and 210, along the east.
Shops and offices mostly stay down along Fort Union Boulevard, home to Mountview Park and the Whitmore Library, while City Hall and Brighton High School share Bengal Boulevard. Butler Park at 7500 South and 2700 East and the Ferguson Canyon Trailhead are reminders of how close the mountains are.
Cottonwood Heights and Its Canyon Water
The Big Cottonwood Water Treatment Plant is in Cottonwood Heights. It's owned and run by Salt Lake City Public Utilities and supplies 40% of the drinking water in that department's regional service area, which includes Cottonwood Heights.
Salt Lake City's 2026 water quality report lists water from the Big Cottonwood plant at about 8 grains per gallon of hardness. That's hard, not soft. Wells in the same system run harder still, so what reaches your tap depends on the blend.
Getting the Most From Your Water in Cottonwood Heights
It's easy to assume canyon water is soft, but at about 8 grains per gallon it's still in the hard range, and wells in the same system run higher. If you've recently added a tankless water heater or a high-end dishwasher, softening now protects the investment. A carbon filter on top of that takes out the chlorine taste from treatment.
Water Softener and Water Treatment in Cottonwood Heights
Even canyon water is hard enough to leave scale, so a water softener is the main fix. If you want scale protection without salt, a Salt-Free Water Conditioner is an option, and a Whole-House Carbon Filter takes out the chlorine taste.
