Denver Water serves more than 1.3 million people in Denver and its surrounding suburbs. The majority of Denver’s water comes from rivers and streams fed by mountain snowmelt. The South Platte River, Blue River, Williams Fork River and Fraser River watersheds are Denver Water’s primary water sources, but it also uses water from the South Boulder Creek, Ralston Creek and Bear Creek watersheds.
Denver Water produces one-third of the state’s treated water supply, which is about 234,000 acre-feet per year. An acre-foot equals 325,851 gallons of water and is enough for about 2 ½ households for one year. Denver Water uses about 265,000 acre-feet of water a year, which is about 2 percent of all water, treated and untreated, in Colorado.
