Water Supply & Demand #

Fort Collins Utilities manages water supply and demand through careful research and analysis regarding streamflow, diversions, climate, customer demand and population estimates to ensure a clean, reliable water supply for customers now and into the future.

Utilities supplies water to approximately 75% of residents and businesses within the Fort Collins city limits. The remaining customers are serviced by surrounding water districts, including East Larimer County Water District and Fort Collins-Loveland Water District. See what service area you are in.

Each year, Utilities typically:

  • Delivers an average of around 24,000 acre-feet per year of treated water to customers
  • Uses approximately 3,000 acre-feet of raw water to irrigate Fort Collins' parks, golf courses, cemetery, and other green belt areas
  • Delivers about 4,500 acre-feet of other raw water obligations

Raw Water Rental Program
