<br />Update on Statewide Water Supply Initiative
<br />- Rio Grande Basin
<br />
<br />Statewide Municipal and Industrial and Self-supplied Industrial
<br />
<br />Demands
<br />
<br />SWSI has examined current water use and supply and has also estimated future water
<br />needs based on a per capita water use methodology. Per capita water use was
<br />obtained from over 75 percent of
<br />Colorado's water providers, and
<br />the data they provided were then
<br />combined with population
<br />estimates from the State
<br />Demographer's Office to develop
<br />future water demand projections.
<br />The results are shown in Table 2
<br />for the year 2000 and year 2030.
<br />The state's eight major water basins
<br />will need an additional 630,000
<br />acre-feet (AF) of new water by the
<br />year 2030 to meet projected
<br />San Juanl demands, 53 percent more water
<br />Dolores
<br />than is being used today. An acre-
<br />foot of water is approximately
<br />Figure 1 Colorado's Eight Major River Basins 326,000 gallons. These projected
<br />water demands are reduced by
<br />anticipated water conservation savings as a result of the National Energy Efficiency
<br />Act, which established mandatory standards for water use efficiency for certain
<br />plumbing fixtures.

<br />Understanding how future water needs will be met is the real challenge that SWSI
<br />will be examining in more detail over the next 4 months. To date, the study team has
<br />identified how the major water suppliers plan on meeting their 2030 demands. This
<br />inventory of solutions includes conservation, water reuse, water transfers,
<br />enlargement and re-operation of facilities, and new facilities. Examples of some of the
