Carolina Water Specialties LLC

Carolina Water Specialties LLC, doing business as Culligan Of The Piedmont, supplies potable water treatment equipment, spare parts, maintenance services, and operational support to U.S. diplomatic facilities worldwide as a full-and-open prime contractor—99% of its recent federal work flows through prime contracts and indefinite delivery vehicles held directly with the Department of State. The company is a self-certified small disadvantaged business structured as a for-profit limited liability company, based in Powdersville, South Carolina, competing on an unrestricted basis without set-aside designations.

The vendor's customer concentration is extreme and immobile. The Department of State's Bureau of Overseas Building Operations accounts for 102 awards (83% of the 123 total) and $3.7 million of the $4.1 million combined potential value. The Bureau of African Affairs places 12 awards ($343 thousand). The remaining five customer organizations—Bureau of Near Eastern Affairs, Bureau of Western Hemisphere Affairs, and three embassy-specific offices—account for a combined $52 thousand. The top two rankings are nearly identical, signaling that OBO dominates both frequency and dollars with no tension between the two metrics.

Carolina Water Specialties holds two active indefinite delivery contracts with the Department of State. The primary vehicle is a single-award IDIQ with the Bureau of East Asian and Pacific Affairs valued at $90,000 (running through September 27, 2027) for domestic water treatment systems and services, primarily supporting diplomatic facilities in Indonesia with supplemental work performed in Easley, South Carolina. The second vehicle is a newer single-award IDIQ with the Bureau of Overseas Building Operations valued at $198,972.36 (running through September 30, 2031) for potable water treatment services at various diplomatic facilities worldwide. Task orders under these IDIQs carry individual ceilings between $16,400 and $18,458 and are priced on a firm fixed-price basis. Representative task orders include a $18,458.34 delivery order (August 2026, domestic water treatment in Indonesia, completion October 2027), a $17,920.72 order (March 2026, Easley, South Carolina, completion May 2027), and a $16,892 order (September 2023, Indonesia, completion October 2024).

Beyond the IDIQs, Carolina Water Specialties wins frequent purchase orders and definitive contracts. Recent named examples include a $102,576.01 purchase order for replacement potable water boost pumps at the U.S. Embassy in Gabon (August 2023, completion August 2024); a $158,210.24 definitive contract for potable water and HVAC service maintenance at the U.S. Embassy in Benin (June 2022, completion May 2027); a $110,581.63 definitive contract for domestic hydronic water systems at the U.S. Embassy in Brazzaville, Republic of the Congo (July 2022, completion August 2027); and a $87,361.33 definitive contract for domestic hydronic water systems, also in the Republic of the Congo (July 2022, completion August 2027). Smaller orders cover spare parts, filters, pump controls, training, and equipment repair across Indonesia, Rwanda, Uganda, Mozambique, Laos, Paraguay, Mexico, Greece, Serbia, Eswatini, and Bahamas.

Award activity peaked in 2023 (18 awards) and declined in 2024 (8 awards) and 2026 (7 awards, year-to-date through mid-September), suggesting no growth trajectory. Nine awards with combined potential value of $517 thousand reach ultimate completion within the next twenty-four months, creating a recompete exposure window. The vendor's capability portfolio is narrow—water purification equipment dominates (30 awards by PSC), followed by maintenance of water supply facilities (19 awards) and repair/rebuild services for water purification equipment (10 awards)—leaving the vendor vulnerable to customer budget cuts or agency consolidation of water treatment procurement. Carolina Water Specialties operates one identified subcontractor relationship: it subcontracted to BL Harbert International LLC on a potable water treatment task for the New Embassy Compound in Kinshasa, Republic of the Congo (February 2026), but this single sub-award represents only 1% of the portfolio and is not the vendor's primary role. The vendor's federal footprint is entirely dependent on State Department water infrastructure programs at diplomatic posts, with zero diversity across other agencies, civilian buyers, or defense customers.
