Section 8
Options for Meeting Future Water Needs
achieve about 10 percent water demand reduction in
the short- to mid-term (10 years).
^ Le~~i S M~! ~~n~~rv~ti~n: Program savings are
influenced by the level of participation and compliance
with a given program. The prior levels of conservation
effort (2 through 4) assume a reasonable level of
program participation. Level 5 assumes total
participation by all customers and is intended to
represent a maximum level of effort in water use
efficiency. Such a level of conservation is estimated to
achieve about 15 percent water demand reduction in
the short- to mid-term (10 years).
It is important to note that the matrix shown in Table 8-1
shows future conservation potential. The SWSI baseline
county water use values of gpcd are based upon year
2000 data and therefore implicitly include the "current"
level of conservation effort. One cannot simply apply an
assumed level of conservation to a county demand
number and expect the referred percent savings,
because water providers may be at or above the
assumed level of conservation.
It is also important to note that the realistic level of future
water demand varies by location given the currently
implemented or budgeted water conservation programs.
For example, Level 3 conservation represents a set of
conservation programs similar to what Denver Water has
already implemented, as of the base year 2000.
Continued implementation of Level 3 programs will
further increase market saturation and enhance program
savings. Therefore, the future water demand for Denver
County should be further reduced by the Level 3
percentages to reflect the future impacts of continuing
the currently implemented conservation programs.
Furthermore, Denver Water is considering for future
implementation a set of programs commensurate with
Level 4. Thus, if the additional programs are
implemented, it would be realistic to further reduce the
Denver County demand projections by the difference
between Level 3 and Level 4(i.e., simply apply the
Level 4 percent reduction). This would provide a realistic
projection of future water demand for Denver County.
However, the base period of the SWSI analysis is 2000.
Therefore, the level of conservation in the year 2000 is
assumed for the current conservation level.
In order to develop a more realistic assessment of future
water demand throughout the state, the appropriate
current (year 2000) level of conservation was identified
~~
for each county. The classification of the level of effort for
each county is subjectively based on a review of
available water conservation plans submitted by water
providers to the CWCB and survey results collected by
the Colorado Municipal League. The resulting
classification of each county is summarized in Table 8-2.
It is estimated that these current active conservation
programs will result in water demand savings ranging
from 3 to 14 percent by basin, or an estimated
231,000 AF, by 2030 if the current level of effort is
sustained into the future. More detail on the estimated
M&I conservation savings is provided in Appendix E.
