Frequently Asked Questions
Why is delivering treated Missouri River water the preferred solution?
By pumping treated water from South Dakota across the Missouri River into Santee, the Nation connects to Randall Community Water District (RCWD) near Wagner, SD. RCWD is a South Dakota rural water system that treats Missouri River surface water upstream of the Fort Randall Dam. The Nation would purchase bulk water from the rural water system.
​
Following an evaluation of development costs and a life cycle cost analysis performed per USDA RD requirements, this project was identified as the preferred solution. It provides the lowest life cycle and annual O&M costs while protecting against future groundwater contamination or depletion.
How is the project funded?
The estimated total project cost to meet Santee’s water supply needs is $43 million, and funding is in progress. Senator Fischer helped secure $8.25 million in FY ‘26 CDS funding within the EPA STAG Drinking Water SRF, complemented by an EPA commitment of $1.75 million. While $8.96 million in directed funds is currently held by IHS to address the health disaster, there is confidence that IHS will release these funds to the EPA; otherwise, the Tribe will need to secure additional CDS funding to bridge the gap. USDA RD will assist in finalizing the total funding package following environmental clearance.
What is the process to design and construct a regional water transmission line?
The project will employ the Construction Manager at Risk (CMAR) delivery method to involve construction professionals early in the design and permitting phases. CMAR requires the Construction Manager (CM) to establish a Guaranteed Maximum Price (GMP) during the preconstruction phase. With this, the CM assumes the risk of cost overruns and budget management, which facilitates faster delivery and reduces overall project uncertainty. This method ensures the contractor is involved during critical early tasks, including design, surveying, landowner easement acquisition, geotechnical, and environmental assessments.
What is the project’s anticipated construction schedule?
Construction will begin once permitting is approved, environmental clearances are obtained, and all preconstruction services are complete. Mobilization is anticipated for Spring 2027, with an estimated 13-month construction timeline. Many activities will occur concurrently, including HDPE pipeline plowing, river boring, and facility construction.
What can landowners within the proposed route expect?
Landowner care is one of our highest priorities and involves respectful communication throughout all phases. Landowners should will kept informed about the project timeline, the location of the waterline, and the measures taken to minimize disruption to their property and agricultural operations. Key aspects of care include prompt and fair compensation for easements, ensuring the restoration of property to preconstruction conditions, and establishing a clear point of contact throughout the project.
How does the plan minimize impacts to the natural environment?
The project water source is supplied by an existing intake to Lake Francis Case on the Missouri
River. Waterline right-of-way will primarily be along existing transportation corridors, and strategic boring locations will be used to minimize impact.
