THE BROADER BENEFITS OF THE COLLABORATIVE
~nwsl PROCESS

The MWSI has been both a technical evaluation of cooperative water supply
opportunities and a continuing process of dialogue, mutual education, joint inquiry, and
cCJllaboration among over 60 Front Range water providers and representatives of other
k;~y stakeholders including environmental organizations, agriculture and the West Slope.
\Vhile this diverse group has focused principally on the opportunities and limitations
associated with the four cooperative water supply categories, participants also developed
and shared considerable information regarding the future water needs of the metro
Denver area and individual water providers' plans that are in place for meeting those
needs.

Tills information, summarized in the table and text below by sub-region, provides
valuable context that enhances understanding of the roles and benefits of the cooperative
water supply opportunities evaluated through the MWSL

(1) Based on their planning efforts to date, water providers have a relatively high degree of confidence in these supplies.
(2) Providers have a relatively lower degree of confidence in their plans to meet these needs, based on uncertainty
factors and the comparatively longer time frames before these supplies would be needed.
(3) Cooperative suppiy opportunities could be used to meet future unmet needs or as an alternative
to reasonably certain future supplies.
(4) Includes Denver Water and Englewood; includes Denver Water's 30,000 AF safety factor.
(5) Based on the expected range of Denver Water's future safety factor.
(6) Includes Aurora's 10,000 AF planning reserve,
(7) Depending on the degree of Implementation of Thornton's Northern Project

The table illustrates that most Denver area water providers have planned for the future
very well and currently have strategies in place to meet projected water needs to the year
2030 and in some cases considerably beyond that date. As described further below, the
cooperative water supply opportunities evaluated in the MWSI could supplement or
partially replace the plans individual water providers already have in place.
