Sources

The City has two sources of water available to meet water demands. The primary source is a 36 square mile area forming the "Mill Creek Watershed". At its upper end lies the headwaters of Mill Creek. The Watershed area is protected. It is closed to the public allowing only limited access in coordination with the U.S. Forest Service. It is patrolled by a City Watershed Attendant and United States Forest Service personnel.
Water from Mill Creek is piped 14.5 miles to the City's Water Treatment Plant where it is treated using UV disinfection and chlorine to meet State and Federal Drinking Water Quality Standards before entering the distribution system.

The Mill Creek Watershed supplies 88-90% of the City's water need. In addition to this primary source, the City also has seven deep (800-1400') basalt wells used to supplement supply when stream levels decline in summer months. In an emergency, these wells would completely supply the city's needs. Wells are typically used when:

  • Surface water quality has changed due to weather events.
  • During the summer to meet increased water demands or when stream levels are low.

Treatment

The City's Water Treatment Plant is capable of producing 24 million gallons of water daily that meets or exceeds Environmental Protection Agency and Department of Health Drinking Water Standards. Quality assurance is provided through stringent lab and system monitoring and testing.  Water is treated using  UV disinfection and chlorine. The City maintains a state certified microbial laboratory at the Treatment Plant which provides efficient and timely water testing, testing results, and allows for rapid adjustments in treatment operations to consistent maintain water quality.

Hydro Power Generation

All water that passes through our Treatment Plant from the Mill Creek Watershed also passes through a hydropower generator which produces 13,500 megawatts of electricity annually (sufficient to power approximately 1,500 homes). Revenue from the generated power is used to offset operation and maintenance costs.
