Self-Supplied Industrial Water users Demand
<br />Major industrial demands within the SPDSS study area not accounted for in municipal water user
<br />demands include six power plants, the Coors brewery, and two ski areas, as summarized in
<br />Table 5. A number of minor industrial demands were identified though a review of the
<br />HydroBase (CO_20070701) water rights tabulation for water rights adjudicated for industrial use
<br />only. These water rights are generally for small amounts and few diversion records are available
<br />in HydroBase. Therefore, only the major self supplied industrial (SSI) water user demands listed
<br />in Table 5 are considered in this effort.
<br />Current demand data and CU rates for the power plants and Coors brewery were provided by the
<br />operators for the SWSI effort. Additional historical demand data for these and other self-supplied
<br />industrial users were gathered from discussions with power plant operators, ski resort operators
<br />and Coors personnel.
<br />Water demands for self-supplied industrial users totaled approximately 82,000 acre-feet per year
<br />in 2000, as summarized in Table 5. Based on the dates these uses came on-line and the increases
<br />in service areas/service capacities, the current self-supplied industrial water demands represent
<br />about a 550 percent increase from 1950 and about a 380 percent increase from 1980. As data was
<br />only provided on a decennial basis, the missing yearly demands were filled with TSTooI using
<br />linear interpolation to provide a complete dataset of SSI water demands.
