The water

What comes out of the tap here, and what it does to a water heater.

  • Cedar City supplies its own drinking water from groundwater: 8 wells and 4 springs.1
  • The utility is Cedar City Waterworks, state water system ID 11002.1
  • Cedar City's water system served 10,414 connections in 2021.1

  • Cedar City's 2025 water quality report gives total dissolved solids of 180 to 804 ppm across its sources, against a limit of 2,000.1
12 more facts, with sources
  • Sulfate ranged from 2.762 to 347.495 ppm across sources in 2025, against a limit of 1,000.1
  • Sodium ranged from 3.573 to 27.517 ppm in 2025; EPA sets no limit for sodium.1

  • The State Engineer has declared Cedar City Valley a critical management area because groundwater withdrawals exceed safe yield.1
  • The state estimates the basin's safe yield at 21,000 acre-feet a year against current depletion of 28,000 acre-feet a year.1
  • If every approved or perfected groundwater right were used, depletion would be about 50,000 acre-feet a year.1
  • Under the 2021 groundwater management plan, water rights will be cut by priority date in five phases from January 1, 2035 to January 1, 2080.1
  • Cedar City owns about 13,000 acre-feet of groundwater rights, of which about 2,800 have enough priority to survive the state's cuts.1
  • The city's own master plan says groundwater in the valley is being withdrawn at an unsustainable rate.1

The associations

What the documents say, by community. Confirm with your own.

  • Cedar Highlands Homeowners Association is an active master HOA registration with the state, number 14258617-MHOA.1
  • The Central Iron County Water Conservancy District runs the Cedar Highlands water system and chose a different tank site after its geotechnical consultant advised against the old one, which sits at the toe of a landslide.1
  • Utah law bars an HOA from prohibiting water-wise landscaping on a detached home's lot (Utah Code 57-8a-231).1
  • Except for erosion control, an HOA may not require lawn in an area less than 8 feet wide.1

The ground

Soils, faults, flood and rockfall, from the state's hazard mapping.

  • The Utah Geological Survey documented land subsidence and earth fissures in Cedar Valley in Special Study 150 (2014).1
  • Groundwater pumping in excess of recharge has lowered water levels in Cedar Valley by as much as 114 feet since 1939, according to the UGS.1
  • Cedar Valley's aquifer contains a high share of fine-grained sediment that compacts when it is drained.1
  • The largest subsidence the UGS measured at a benchmark was 0.9 foot, near Enoch; vertical offset across the Enoch fissure zone is about 3 feet in places.1
  • At least 8.3 miles of earth fissures have formed in the southwestern and northeastern parts of Cedar Valley.1
  • The UGS concluded that long-term groundwater pumping in excess of recharge is the cause of the subsidence and fissures.1
13 more facts, with sources
  • If water levels keep falling about 2 feet a year, the UGS expects basin-wide subsidence of 0.02 to 1.2 inches a year to continue, and new fissures to form.1
  • Satellite radar (InSAR) identified about 100 square miles of Cedar Valley subsiding from groundwater mining.1
  • The UGS says the fissure inventory is likely incomplete, because many fissures are hairline cracks hard to see.1
  • Documented fissure damage is limited to the Parkview subdivision in Enoch and a stock pond west of Quichapa Lake.1
  • In Enoch's Parkview subdivision, fissure movement reversed the flow of a sewer line so it could no longer drain by gravity; the UGS calls it the first extensive fissure damage to the built environment in Utah.1
  • Several large-capacity Cedar City municipal wells sit near the fissure zones around Quichapa Lake.1
  • Subsidence can continue long after groundwater decline stops, because clay layers take years to decades to finish compacting.1
  • The UGS's 2025 hazard study (Special Study 177) says collapsible soil and flooding have been the costliest geologic hazards in Cedar Valley.1
  • The UGS identifies radon gas as a hazard in the Cedar Valley study area.1
  • The UGS also maps expansive, corrosive and soluble soil and rock, shallow groundwater, landslide and rockfall hazards in Cedar Valley.1
  • The UGS hazard maps are public on the Utah Geologic Hazards Portal and are not a substitute for a site-specific investigation.1
  • Collapsible soil in Cedar City itself was studied as far back as 1978.1
  • The Hurricane fault runs along the Hurricane Cliffs at the east edge of Cedar Valley, and the cliffs are up to 2,000 feet high.1
