The marquee programs rebuilding U.S. water infrastructure

Five programs whose scale, funding, or first-of-kind profile mark them as defining builds for the 2025–2032 water infrastructure construction cycle.

Spotlight 01 · Under Construction

Bull Run Filtration Project (Portland, OR)

Portland Water Bureau · Filtration facility + raw and finished water pipelines · Delivery this decade

The largest active drinking-water treatment build in the country.

Methodology

How iRecruit.co tracks water infrastructure construction

Every program shown is compiled from public filings, utility and district announcements, WIFIA and state SRF funding records, and our own placement work across the segment. We surface programs with confirmed owner sponsorship at procurement, design, construction, commissioning, or recently-completed stages.

What makes a program the tracker

To appear in the tracker, a program must meet at least three of the following criteria:

Publicly confirmed utility, municipal, district, or authority owner as program sponsor.
Disclosed location at minimum to metro / municipality level.
Public size figure (MGD capacity, storage volume, tunnel length, or program dollars).
Confirmed status (procurement, design / permitting, under construction, commissioning, or recently completed).
Sourced from public filings, owner press releases, WIFIA / SRF records, or established trade publications.
Active within the 2024–2032 delivery window relevant to current water infrastructure recruiting demand.

We refresh the tracker as programs are announced, status changes occur, or capacity and funding figures are updated. The tracker is maintained by iRecruit.co’s research team in coordination with our active placement work. Verify all data before referencing in formal documents. Some program specifics (MGD figures, $ values, contractor assignments, timelines) may have evolved since compilation.
