Water Use

Water_Use_sprinklerWater use from year to year is heavily influenced by the weather. About half of single-family residential water use is outdoors, and a hot, dry year can mean customers need to use more water than usual. Predicting the future needs for Denver Water's service area depends on growth in population and employment, improvements in water fixture technology, and changes to land use, among other variables.

Denver Water analyzes how customers use water now and how that use may change in the future. By researching customer water-use patterns, we are able to better plan for an adequate supply of clean, reliable water well into the future.

Denver Water serves about a quarter of the state's population but uses less than two percent of all water, treated and untreated, in Colorado.

Denver Water’s total retail treated water use by category:

  • 48 percent single-family homes
  • 23 percent business and industry
  • 19 percent multifamily homes
  • 6 percent irrigation-only
  • 4 percent public agencies

Average single-family residential customer’s water usage: 

  • 50 percent outdoor use
  • 12 percent toilet
  • 11 percent shower
  • 9 percent clothes washer
  • 8 percent faucet
  • 5 percent leaks
  • 3 percent other
  • 1 percent bath
  • 1 percent dishwasher

One strategy to meet future needs — in addition to recycling water and building new supply projects  — is by conserving. Using water efficiently can stretch our supplies well into the future.
