Williamsburg County

Williamsburg County Government, a South Carolina county entity based in Kingstree, operates as a federal prime recipient for grant-funded infrastructure and utility services, predominantly under Department of Agriculture rural development and Department of Transportation airport improvement programs. The county does not hold federal contract IDVs or prime contract vehicles; its federal engagement centers on direct grant awards and purchase orders for essential services, with no SBA set-aside designations across its portfolio.

Williamsburg County's federal footprint consists almost entirely of prime grant awards (93% of 168 total awards) concentrated in rural utility infrastructure, watershed management, and local airport development. The Department of Justice Bureau of Prisons drives contract volume — a series of firm fixed-price purchase orders for water and sewer services at the Federal Correctional Institution Williamsburg in Salters, South Carolina, spanning $71,441 to $236,629 per order from 2021 through 2023. However, grant work dominates the dollar pipeline. The Department of Agriculture's Rural Utilities Service and Rural Housing Service jointly anchor fourteen awards totaling multiple millions across water and waste disposal systems (CFDA 10.760), community facilities development (CFDA 10.766), and the Watershed Protection and Flood Prevention program (CFDA 10.904). Representative grant work includes a $5.4 million cooperative agreement for the Black River 7 Watershed Flood Prevention Project awarded August 2023 (completion September 2027), a $3.6 million cooperative agreement for the Middle Black River Watershed Project awarded September 2025 (completion September 2027), and a $5.1 million cooperative agreement for the Black River 9 Project awarded September 2023 (completion September 2027). The Federal Aviation Administration Southern Region awards project grants for Kingstree Airport infrastructure, including a $1.27 million grant for hangar and apron construction (June 2022 award, completion June 2026), a $295,789 grant for aircraft storage hangar construction awarded September 2025, and a $343,753 grant for runway rehabilitation and lighting design awarded August 2024.

Top customer concentration is extreme: the Department of Justice Bureau of Prisons accounts for 53 awards and the full $9.1 million in combined potential value across contracts, while the Department of Agriculture Rural Housing Service, Rural Utilities Service, and their subordinate components collectively hold 56 awards supporting watershed and utility infrastructure. Across the entire 168-award footprint spanning 2001 to present, the top five customer agencies account for 71% of award count. Award velocity has declined — ten awards in 2022, five in 2023, three in 2024, six in 2025, and three in 2026 year to date — with only two awards holding ultimate completion dates within the next twenty-four months and therefore facing recompete exposure in that window.

Williamsburg County acts as a subgrantee on nine federal grant awards issued by the South Carolina Department of Social Services (Title IV-D child support enforcement services to Williamsburg County Clerk of Court and Sheriff's Department), the South Carolina Adjutant General (hazard mitigation plan updates and emergency protective measures), the South Carolina Department of Public Safety (law enforcement mobilization grants), and through a Section 5311 transit administration and operations subaward. The county's capability footprint concentrates in sewage treatment facilities (47 awards), water supply and irrigation systems (10 awards), and utilities operations under PSC Utilities-Water (51 awards), reflecting its primary role as a local government entity providing essential services rather than as a federal contractor pursuing competitive solicitations.
