Executive Summary

Throughout Colorado the competition and expense for water supplies is increasing
while the availability of water is decreasing. The Town of Erie (Erie) is among many
communities in the Front Range that anticipate significant growth and increases in
water supply needs.

One way to help reduce water supply expenses and be a steward of the state's
valuable resource is to conserve water. As the cost of water rises, the economic
benefits associated with conservation will increase. Conservation is an important
component of Erie's water management strategy.

This Conservation Plan (Plan) provides guidance for effective water conservation
while controlling implementational costs. This Plan evaluates Erie's water demands
and supplies, defines goals specific to the conservation program, and evaluates and
selects conservation measures/programs for implementation. This Plan focuses on
conservation measures and programs that are compatible with Erie's water supply
system, water resources management strategy, and community values.

Conservation Goals

The development of attainable water conservation goals are a key component to the
success of a conservation program. Goals provide a specific set of standards that can
be used to gage the effectiveness of a program as well as clearly define the
expectations for the program. The goals listed below were developed with the
objective of targeting a specific amount of water conservation savings, while also
providing the ability to monitor the results of the conservation program on an annual
basis. The goals are as follows:

1. Annual per capita water usage of 221 gallons per capita per day (gpcd) by 20141.
This annual per capita water usage provides a 2014 water savings of 1,350 acre-
feet per year (AFY)2,3 (20 percent) relative to the projected demands absent
conservation and use of reclaimed water. See Section 5.2 for additional
information.

2. 740 AFY4 of reclaimed (reused treated effluent) water use by 2014 (assuming
approximately 400 AFY of reclaimed water use at Vista Ridge) to the extent that
development occurs as anticipated and the reclaimed water system is constructed.

1 The per capita water usage will be calculated using the population projections provided in
Section 3.3 and the total annual first-use water usage of billed and unbilled potable water,
raw water, and leased water. The per capita water usage of 221 gpcd does not include use of
reclaimed water.
2 An acre-foot is equivalent to 325,851 gallons.
3 As discussed in Section 3, the per capita water usage of exclusively billed potable water would be
significantly less than the 221 gpcd used for purposes of this Plan.
4 This savings is included in the total water savings presented in Goal #1.
