moving forward

The process to develop, construct, and eventually operate a regional water system takes years of research, planning, and coordination.

In 2024, the Dakota Mainstem Regional Water System contracted with a collaborative teaming partnership composed of HDR, Banner & Associates, Bartlett & West, DGR Engineering, and WCS Engineering for the delivery of an Appraisal Study.

 

Appraisal Study

Appraisal Studies are used to determine the nature of water and related resource problems and needs, formulate and assess preliminary alternatives to address the problems, establish whether there is a federal interest in working with partners to pursue a solution and identify potential project beneficiaries. If a federal interest exists and one or more viable alternatives are identified, a completed appraisal report may recommend a feasibility study of a new federal project or modification of an existing project.

An Appraisal Study is required before a Feasibility Study unless an equivalent analysis has been completed. An Appraisal Study will define the problem, needs, project area, participants, proposed solution(s), and any obstacles that might preclude federal or the cost-share partner’s participation.

The Appraisal Study will explore:

  • Identify the needs

  • Available alternatives

  • Environmental impacts

  • Cultural impacts

  • Site and route determination

  • Best practices and design

  • Treated water standards

  • Pipeline materials

  • Pumping and storage strategies

  • Financing options

Feasibility Study

A Feasibility Study evaluates the technical, economic, and financial feasibility of a proposed alternative based on detailed investigations requiring the acquisition of primary data and including an assessment of environmental impacts as required by the NEPA. The Feasibility Study will provide the basis for making recommendations to Congress about whether a proposed alternative will be authorized for implementation and Federal funding.

The Feasibility Study will research:

  • Project justification

  • Engineering concepts

  • Cost estimates

  • Environmental and cultural findings

  • Governance recommendations

  • Funding strategies
