Government contracts for plumbers in Wisconsin

Plumbers contracts in Wisconsin typically cover backflow-preventer testing, water-main repair, fixture replacement at federal buildings, sewer-line work at correctional facilities, and on-call plumbing IDIQs. Federal posts in this category fall under NAICS 238220 (Plumbing, Heating, and Air-Conditioning Contractors), and the bulk of the work flows to the Army Corps of Engineers, the Federal Bureau of Prisons, and GSA. Small-business set-asides are common because most jobs sit well below the simplified acquisition threshold.

As of October 20, 2026, Wisconsin has 4 open plumbers contracts in our database, with 4 added in the last 30 days. Volume in smaller markets is lumpy: a single base or facility can drive a quarter of annual postings. The most active buyers are University of Wisconsin Eau Claire (1 open posts) and University of Wisconsin Madison (1), with the rest spread across other federal civilian agencies, DoD components, and state and local departments active in Wisconsin.

Beyond federal opportunities, much of the plumbers work in Wisconsin is posted through VendorNet (Wisconsin DOA), with recurring buyers including the Wisconsin Department of Transportation and the University of Wisconsin System. The Department of Administration enforces statewide minority- and woman-owned business participation goals on contracted spend. ContractRadar pulls federal postings from SAM.gov alongside state and local feeds so a plumbing contractor doesn't have to monitor each portal manually.
