8.4 Summary of Forecast Modifications and Benefits of
Conservation

Figure 8-1 shows the projected demands with and without conservation as well as an
assumed surface water supply capacity of 2,000 AFY and reuse of 240 AFY. Projected
demands with conservation were estimated by subtracting the total of the water
saving estimates presented in Section 7.2. As discussed in Section 8.1, these water
estimates were reduced by 20 percent to compensate for overlapping demands and
uncertainty on the level of customer participation.

Figure 8-1
Supply and Projected Demands with and without Conservation

As discussed in Section 8.2, conservation will not significantly affect future capital
expenditures or the timing of development of new infrastructure. However,
conservation can reduce the amount of water consumed and consequently the
operation and maintenance costs to produce treated drinking water. Significant
conservation savings may also reduce the amount of water rights that are needed to
be purchased for surface water supplies.

8.5 Revenue Effects

Conservation can reduce the amount of revenue received by the District. As the
amount of water used by customers decreases, the less revenue the District receives.
Figure 8-2 shows projected revenues based on projected demands with and without
conservation. It is assumed that the District charges an average of $3.67 per
1,000 gallons for water. This price was derived by calculating a weighted average of
2006 tiered water rates and the projected amount of usage per tier.
