Project Development Tasks: the following tasks will be part of the Feasibility Study but are common to
both Water and Wastewater Regionalization work:
· Regionalization Governance Structure and Management Alternatives
· Economic Impact Analysis & Funding Development
· Cost-Share and Financial Structure Development
· Project Cost Analysis and Scenario Planning
· Public Outreach and Education Planning
Regionalization Governance Structure and Management Alternatives
Consultant shall provide guidance on how the regionalization effort may be organized, governed, and
managed. Each jurisdiction will want to show that it can exercise and protect the rights of their users.
Consultant shall provide examples that comply with Montana Code Annotated (MCA) 75-6-305 and have
been used successfully in other similar regionalization endeavors.
Economic Impact Analysis and Funding Development
Develop a long-term economic impact analysis that identifies and quantifies the economic limits on the
Gallatin Valley without additional water supply(ies), and the potential economic benefit with additional
water supply(ies). Together with the environmental benefits of the project (fewer septic systems and
groundwater withdrawals), the economic development impact will form the basis of any justification for
the project when pursuing funding from State and Federal partners.
The funding development phase will include a two-pronged approach:
1. Research and identify large funding programs that could be used to fund portions of either or
both the water and wastewater regionalization projects. The funding review will be limited to
large programs and sales tax efforts that have the potential to fund significant aspects of the
project as opposed to smaller programs.
2. Collaborate with the conceptual design team to identify aspects of the project that can be
modified to increase the likelihood of federal funding procurement, and any phasing
alternatives that can be considered to improve the likelihood of funding success.
3. Outline arguments in support of a local sales tax effort, and coordinate meetings with Gallatin
Valley area state representatives.
Cost-Sharing and Financial Structure Development
Outside sources of funding (State, Federal, and potential public-private partnerships(P3)) will likely be
critical to the success of regionaliation, but some level of self-funding will be necessary to provide local
matching funds and/or to finance portions of the project that cannot be funded with outside sources.
Appropriate, fair, and equitable cost-sharing will be critical to stakeholder participation in
regionalization endeavors. Consultant shall identify, quantify, and explain a logical cost-sharing
breakdown between local jurisdictions, for both upfront capital and long-term OM&R costs. The cost-
sharing analysis shall evaluate the following, to the extent possible at this stage:
DRAFTDocuSign Envelope ID: D268493F-AF3E-428C-90F7-4AE36CC38F58
· Differences in populations served within each jurisdiction
· Differences for Cost of Service due to population size, water use, wastewater generation,
geographic location, level of service, wastewater treatment requirements, etc.
· Incorporation of any capital that a local entity may contribute to the project(s)
· Incorporation of any water or wastewater infrastructure, resources or water rights that a local
entity may contribute to regionalization
· Accommodation of potential differences in future growth patterns between jurisdictions
The above tasks will not be completed at this stage, instead the goal of this feasibility effort will be to
identify long-term financial implications of regionalization for each jurisdiction, and how others may
financially benefit from joining the regionalization initiative.
Project Cost Analysis & Scenario Planning
Financial team shall utilize the capital and OM&R cost estimates developed by the engineering team to
identify the financial impacts of the various project components.
Consultant shall develop a preliminary cost-share model that uses the cost estimates developed for
projects to estimate the potential impact on participating jurisdictions.
The goal will be to compare current rates and impact fees, and the potential for future rate increases for
each jurisdiction with and without regionalization, to potential rates and impact fees for regionalization
partners. The rates calculated through this will be generalized based on the projected cost-share
allocated to each jurisdiction and the number of users (or total flows). Detailed scenarios will not be
prepared for all users or rate classes.
Summary and Recommendation
Summarize the work described above and provide roadmaps for both water and wastewater
regionalization. Identify key milestones as well as future work required to implement regionalization,
including permitting, water rights, environmental studies, engineering, financial evaluations, and
funding pursuits. Provide cost/fee estimates for work shown on the roadmaps. Also identify potential
decision-making points on the roadmap where if all or part of the regionalization to halt the pursuit of
regionalization.
Describe incentives and benefits of regionalization, along with the disadvantages, impediments, and
potential harms of regionalization.
Provide a final recommendation on next steps, depending on the outcome of cost estimates, financial
capacity and cost-benefits, and drawbacks of Gallatin Valley water and/or wastewater regionalization.
Items/Tasks/Level of Effort Specifically Not Included in the Scope:
· Preliminary design (20% plus) is not included in this scope. The level of design will be conceptual
(5 to 10%). These values are in comparison to 100% design, which is appropriate for bidding.
Engineer will estimate costs based on a combination of recent experience with similar
infrastructure and associated schedules of values from contractors, parametric cost estimation,
and adjustments for items such as terrain challenges, open land versus urban land, etc.
DRAFTDocuSign Envelope ID: D268493F-AF3E-428C-90F7-4AE36CC38F58
o Pipelines will be estimated at cost/diameter-inch/mile, with separate line items for soft
costs (survey, engineering, ROW, easement, construction administration).
o Treatment facilities and pump stations will be estimated based on engineer’s recent
experience with similar facilities and if necessary or critical to developing a Class 4 AACE
level cost estimate, parametric cost models.
o Buildings (treatment buildings, pump stations) will be estimated on $/ft2 basis, using
consultant teams experience and with consideration given to local extremes in public
works construction costs.
· Final Pipeline Routing: ultimate pipeline routing would be determined with more detailed
engineering analyses, easement and Right-of-Way studies and ability to acquisition. A full
Pipeline Route Study will be necessary if regionalization projects move forward.
· Final treatment facility and other vertical infrastructure locations: these will be based on logical
locations at this stage of the study. Ultimate locations will be determined based on longer-term
studies of efficiencies, access, and environmental permitting.
· No more than three cost-share allocation scenarios will be provided at this time with detailed
cost-share implications generalized for additional users and not targeted at any specific
jurisdiction that is not currently participating
· A detailed rate design will not be conducted for the individual users, but rather system-level
usage and account numbers will be used to derive general rate impacts
· The economic impact analysis will not target individual sectors, but the region as a whole
