About plumbers contracts in South Carolina
Plumbers contracts in South Carolina 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, South Carolina has 16 open plumbers contracts in our database, with 12 added in the last 30 days. That's a steady cadence — enough flow to make automated alerting worthwhile rather than manual portal-checking. The most active buyers are Dorchester County (1 open posts) and Town of St. George (1), with the rest spread across other federal civilian agencies, DoD components, and state and local departments active in South Carolina.
Beyond federal opportunities, much of the plumbers work in South Carolina is posted through the South Carolina SCEIS / SCBO bid system, with recurring buyers including the South Carolina Department of Transportation and the University of South Carolina / Clemson. The state publishes its contracts through SCBO (South Carolina Business Opportunities) — daily monitoring is the simplest way to catch new awards. ContractRadar pulls federal postings from SAM.gov alongside state and local feeds so a plumbing contractor doesn't have to monitor each portal manually.
