Water infrastructure intelligence — North Dakota

The most concrete movement this cycle is in Mandan, where a wastewater treatment project appeared on the priority list for the first time with a requested $114.2M and a listed rank of #244. Wahpeton also appeared on the list for the first time, with a wastewater treatment project requesting $85.0M at rank #107. Both entries sit within the Clean Water / Wastewater program track and both are new to the SFY2026 Clean Water SRF IUP relative to the SFY2025 version.

On the Drinking Water SRF side, Flaxton climbed in priority rank to #34 for a water main, gate valve, and hydrant replacement project with an estimated cost of $986K. Maxbass climbed to rank #36 for a curb stop and gate valve replacement project estimated at $600K. Neither entry carries language about funding status beyond its placement on the list; movement in rank is the only change reflected in the data for these two communities.

Across the category rollup, collection and sewer work accounts for the largest share of both project count and value, with 225 projects totaling $1.1B. Wastewater treatment follows at 71 projects worth $604.9M, then stormwater at 64 projects worth $461.3M, watermain and distribution at 147 projects worth $440.2M, water treatment at 34 projects worth $337.4M, and lead service lines at 49 projects worth $151.7M. The concentration of value in collection and sewer work, combined with the size of the Mandan and Wahpeton treatment requests, points to wastewater infrastructure as the dominant driver of the $846.4M in new listings this cycle.

The net cost change of +$253.0M across 282 projects, with more than twice as many increases as decreases, shows estimate revisions moving in one direction more often than the other on this list. Whether any of the 180 newly listed projects or the 78 rank-up projects move further toward the fundable range will depend on future IUP cycles; this document reflects only where each project stands as of 2026-10-05.
