About the company
S4 Water Sales And Service, LLC, a service-disabled veteran-owned small business based in Bowling Green, Kentucky, supplies water treatment chemicals, mechanical cleaning services, and closed-loop system equipment to the U.S. Department of State as a prime contractor competing in full-and-open procurements without set-asides. The company operates exclusively as a prime on small-dollar purchase orders; it holds no subcontract positions and no parent vehicles.
S4 Water serves a single customer agency: the Department of State's Bureau of Overseas Building Operations, which accounts for 17 of 18 recent awards ($787 thousand combined potential value), with the Bureau of African Affairs placing one award ($26 thousand). Across the past five years (2022–2026), the company has maintained consistent activity at roughly three to four awards annually, totaling $813 thousand in combined potential value across all eighteen prime awards. The portfolio is 100% obligated, with no unobligated ceiling value remaining.
S4's capability portfolio centers on water infrastructure support for diplomatic facilities worldwide. Representative work includes a $219,571 purchase order (July 2022) for mechanical water chemicals (glycol), a $74,645 order (September 2025) for closed-loop system equipment and parts, a $66,456 order (February 2024) for chemical treatment services and supplies including test kits and corrosion inhibitor feed systems, a $56,756 order (December 2022) for closed-loop cleaning, passivation, and treatment, a $43,480 order (April 2023) for chemical and test kits on compound water treatment projects, and a $32,108 order (March 2026) for technical cleaning of newly installed chiller systems in Senegal. The company also delivers hydronic pipe flushing services, chilled water system treatment, and water treatment chemical supplies to overseas posts. All awards are firm fixed-price purchase orders with no set-aside designation, reflecting competitive award based on technical capability and pricing.
Two awards (combined potential value $103 thousand) face ultimate completion within the next twenty-four months and will therefore face recompete exposure. The company's narrow customer concentration — entirely within State Department facility operations — creates significant revenue dependency on a single bureau and limits diversification into other federal agencies.
