suburban water suppliers to coordinate their efforts so as to avoid piecemeal fragmented
I
planning. To the extent that individual members ofthe TAC were interested in more
d~tailed investigations in any of the study areas, it was anticipated that such
irlvestigations could take place through cost sharing arrangements with the state. It was
~ticipated that these investigations would provide the basis for continuing discussions
beyond the conclusion of the MWSI and could possibly lead to the implementation of
cooperative projects.

In consideration of these factors, the PMT decided that the originally planned Phase IV
effort to develop and evaluate conceptual design plans should take place in these sub-
regional planning efforts. This would allow water suppliers from each of the sub-regional
areas to have a more direct involvement with the formulation of conceptual plans in
conjunction with continuing the cooperative communication and coordination process
established under the MWSI. To facilitate this effort, the CWCB authorized the use of
funds originally budgeted for Phase IV, on a matching basis, for sub-regional planning
efforts.

2.3. COORDINATION WITH OTHER STUDIES I
PROCESSES

Another critical factor that influenced the evolution of the MWSI was its relationship
with other studies and planning processes that were ongoing at the beginning of the
MWSI or initiated while the MWSI was undelWay. These related studies and plamiing
processes included the following:

. When the MWSI was initiated, the Metro Wastewater Reclamation District was
engaged in extensive effluent management studies that included the analysis of
water management options such as exchanges and reuse.

. Denver Water was in the early stages of implementing an Integrated Resource
Planning Process (IRP) to identify and evaluate alternative water supply planning
strategies. In conjunction with this effort a new raw water supply plamiing model
for the Denver system (P ACSM) was developed as a tool for evaluation of new
water supply sources and system management alternatives,

. The Arapahoe County Water Resource Authority, the Douglas County Water
Resource Authority, Denver Water and Aurora were involved in studies of non-
tributary groundwater resources that included investigations of recharge potential
and potential interconnection with surface water facilities in order to facilitate
conjunctive use of surface and groundwater resources.

. Mayor Wellington Webb was inthe process of initiating a planning effort for
revitalization of the urban South Platte River corridor that included plans to
address urban South Platte instream flow and water quality issues.
