About the company
Seohaehwangyeonggaebal, a for-profit South Korean environmental services contractor based in Gunsan, provides sewage removal, sewer jetting, and waste-disposal services to the U.S. Air Force as a prime contractor on a single-award indefinite delivery contract held by Pacific Air Forces. The vendor operates exclusively as a prime (100% of recent awards) with no set-aside designations across its federal footprint, and has not held subcontracts or received federal grants.
The vendor's federal customer base consists entirely of Pacific Air Forces. All five awards in the source portfolio—one indefinite delivery contract and four delivery orders—were issued by or under this single customer, representing $2 million in combined potential value. Obligated dollars across all awards total $427 thousand, indicating that roughly 21% of the potential ceiling has been drawn to date.
Seohaehwangyeonggaebal holds a single-award indefinite delivery contract (W90VN723D0003) with Pacific Air Forces, valued at $1.567 million with an ultimate completion date of May 31, 2027. Under this IDIQ, the Air Force has issued four delivery orders since June 2023, ranging from $53,895.70 to $158,186.51 per order. The most recent delivery order, awarded December 1, 2025, carries a ceiling of $120,325.19 and extends through November 30, 2026. The IDIQ enables ongoing monthly sewer jetting, septic tank cleaning, grease trap maintenance, and domestic sewage disposal services at Kunsan Air Base in South Korea, with unscheduled maintenance services as needed.
Work is performed entirely at Kunsan Air Base, South Korea. The vendor's service portfolio is narrow and specialized — categorized under Septic Tank and Related Services (NAICS) and Housekeeping-Facilities Operations Support (PSC) — and is limited to infrastructure maintenance and environmental support for a single U.S. military installation. One award (the December 2025 delivery order, $120,325.19) reaches ultimate completion within the next twenty-four months and faces recompete exposure. Activity shows a declining trend: three awards in 2023, declining to one award each in 2024 and 2025, suggesting potential contract recompete or consolidation risk in the near term.
