Section 8
Integrate Resources and Modify Forecasts

This section summarizes the projected water conservation savings and financial
implications of the proposed conservation measures/programs.

8.1 Water Conservation Savings Estimates and
Conservation Goals

The water conservation measures and programs selected for implementation in
Section 7.4 are estimated to total approximately 1,080 AFY of water savings. However,
as shown in Table 7-3, the water savings for many of the conservation measures and
programs could not be estimated to a reasonable degree of certainty and were not
included in the 1,080 AFY estimate. Total water savings could be significantly higher.
Water Conservation Goal 1 presented in Section 5.1 targets a total water savings of
1,350 AFY. This may be achievable with the selected measures and programs if the
actual water savings in 2014 exceeds the quantifiable estimated water savings of
1,080 AFY.

Conversely, there is a degree of uncertainty in the assumptions used to calculate the
available water savings estimates. Actual water savings could ultimately be less than
the estimates provided and total water savings of Erie's conservation program could
be significantly less than the estimated 1,080 AFY. Section 9.3 describes the
monitoring plan Erie plans to implement. Water savings will be evaluated on an
annual basis and if warranted, adjustments could be made to the conservation
program to achieve a higher degree of water savings.

8.2 Summary of Demand Forecast Modifications

Figure 5-2 shows the projected demands with and without the targeted conservation
water savings specified in Conservation Goals 1, 2, and 3. If the water conservation
savings goals are achieved, total water demand (potable, raw, and reclaimed water
use) could be reduced by 610 AFY through demand management. Twelve percent
(740 AFY) of this demand could be met through use of reclaimed water. This would
further reduce potable/raw water demands, resulting in a total water savings of
1,350 AFY.

8.3 Identification of Proj ect-Specific Savings

Generally speaking, successful conservation practices can reduce water demands and
consequently eliminate, downsize, or delay the need for water supply capital projects.
Conservation can also reduce the amount of water rights that need to be purchased to
meet customer needs. This can provide significant cost savings. These savings need to
be considered in light of implementation costs for the conservation measures and
programs.
