Iwakuni City Waterworks Bureau

Iwakuni City Waterworks Bureau, a foreign government entity and subsidiary of Iwakuni City, Yamaguchi Prefecture, Japan, delivers potable water distribution and treatment infrastructure to support U.S. military operations in the Pacific region as a prime contractor on recurring Marine Corps delivery orders. The bureau operates exclusively on full-and-open, non-set-aside basis and holds no SBA designations; as a foreign government municipal utility, it competes outside the domestic small-business framework.

The bureau's federal footprint centers entirely on water supply services to U.S. military installations in Japan. Recent representative work includes a $1.6 million firm fixed price delivery order from the Marine Corps awarded April 1, 2026, for water distribution and infrastructure support at Marine Corps Air Station Iwakuni and related facilities, due for completion by September 30, 2026; a $1.62 million delivery order awarded October 1, 2025, running through September 30, 2035; and a $1.5 million delivery order awarded October 1, 2024, also extending through 2035. All awards carry firm fixed price terms and carry no set-aside designation. Place of performance is Japan.

Customer concentration is acute and single-agency. The United States Marine Corps accounts for 20 awards (97% of award count coverage) and $24.8 million in combined potential value. The Department of the Air Force appears in 51 awards across two indefinite delivery contracts but with no named potential value listed in the source; the Defense Finance and Accounting Service and the Department of the Air Force Pacific Air Forces contribute nominal volumes. The Marine Corps relationship has run consecutively since 2021 and demonstrates the long-term and recurring nature of the bureau's water-services role.

The bureau sits on two parent indefinite delivery contracts: Indefinite Delivery Contract F6256292D8000, which carries 51 task orders, and Indefinite Delivery Contract FA520907G0009, which carries 23 task orders with $26.4 million in combined potential value. The category concentration reflects the nature of the business: 58 awards fall under PSC Utilities-Water, 24 under NAICS Bottled Water Manufacturing, and 18 under PSC Water Purification Equipment.

Award frequency has remained flat at two awards per year across 2022 through 2025, with one award recorded in 2026 to date. Combined potential value stands at $26.4 million across 76 total awards, though combined dollars obligated total $50.4 million (191% of potential value), indicating that invoiced performance has exceeded contractual ceiling values or that prior-year obligations have accumulated. The most recent award in April 2026 reflects continuation of the established delivery-order cadence with the Marine Corps.
