The city of Cottonwood Heights doesn’t run its own water department. About 90% of the city gets drinking water from Salt Lake City Public Utilities, and the rest, mostly around Union Park and a pocket south of Creek Road near Oakdale Elementary, is served by Jordan Valley Water Conservancy District. There’s no secondary water system either, so your sprinklers run on the same treated water as your kitchen tap.
Most of that water starts in Big and Little Cottonwood Canyons, and it’s moderately hard. Salt Lake City’s 2026 water quality report lists 136 ppm (about 8 grains per gallon) at the Big Cottonwood treatment plant. In summer, when canyon runoff drops, the city blends in well water, and its wells tested anywhere from 9.6 to 33.4 grains per gallon. That seasonal shift is why we check softener settings and look for scale buildup when we service a water heater.
Sewer service comes from Cottonwood Improvement District, which has handled wastewater here since 1955. Something a lot of homeowners don’t realize: under the district’s rules, the sewer lateral running from your house to the main belongs to you, including the part under the street. If that pipe cracks or fills with roots, the repair falls to the homeowner, and that’s work we handle with camera inspection and trenchless lining.
Cottonwood Heights sits between 4,500 and 5,100 feet, and the city’s building division sets frost depth at 30 inches, which matters for main water lines and outdoor shutoffs. Plumbing work here follows the 2021 International Plumbing Code with Utah amendments, and we take care of the permit process with the city for you.

Is the water in Cottonwood Heights hard enough to recommend a softener?
We think so, because it’s moderately hard. SLC’s 2026 report shows about 8 grains per gallon at the Big Cottonwood plant, and hardness can increase in the summer when it’s blended with well water.
Who’s responsible for the sewer line between the street and my house?
Cottonwood Improvement District maintains the main, but the service lateral from your home to the main belongs to the property owner, including the part that’s under the road. For a problem with the public sewer main itself, call the district at (801) 943-7671.
Do I need a permit for plumbing repairs in Cottonwood Heights?
Many plumbing projects require a permit from the city’s building division, which enforces the 2021 International Plumbing Code. So when your needs require a permit, we’ll handle it on your behalf.
Do you offer emergency/urgent plumbing services?
We handle emergencies like a broken pipe, sewer backup or failed water heater and others. If you call us immediately we can let you know our time frame.
