World-wide Water Storage Tank Remediation

The Department of State Bureau of Overseas Building Operations awarded a Master IDIQ for worldwide concrete water storage tank remediation on April 22, 2021, with a shared ceiling of $25 million and a last date to order of April 21, 2026—which has closed as of today. The vehicle was established as a multiple-award IDIQ with partial small-business set-asides, reserving one award each for a woman-owned small business and a small business, with one full-and-open award.

Ordering is no longer available. The vehicle's lifecycle has concluded, with the last task order awarded on July 7, 2026, one week before the ordering deadline passed. Across its five-year period, the vehicle issued 39 task orders with combined potential value of $210.4 million, against which only $11.9 million has been obligated (6% of combined potential). Ordering activity peaked in 2023 with 13 awards, declining to 3 awards each in 2024 and 2026, with 8 awards in 2025 and 6 in 2022.

Scope encompasses assessment, repair, and interior coating of concrete water storage tanks at U.S. diplomatic facilities worldwide, including labor, supervision, transportation, tools, equipment, materials, and supplies. Task orders reflect this mix: recent awards include coating services at the U.S. Embassy in Kigali, Rwanda ($955,618), tank assessment and repairs in Dhaka, Bangladesh ($74,652), and assessment and repairs in Brazzaville ($463,680). Orders are priced on a firm-fixed-price basis.

Watertight Solutions LLC dominates the vehicle, holding 26 of 39 orders representing $207.2 million of the $210.4 million combined potential value—roughly 98% of activity. Ease / SSC LLC holds 8 orders valued at $2.8 million, and Tidewater, Inc. holds 5 orders valued at $437 thousand. All 39 task orders fund a single customer: the State Department Bureau of Overseas Building Operations.

The set-aside distribution shifted over the vehicle's life. The 39 orders show 64% with no set-aside (25 orders) and 36% designated Total Small Business (14 orders). Early 2023 activity concentrated small-business awards; recent 2026 awards again used small-business set-asides.

Task-order values range from under $60,000 to roughly $1 million, with typical awards between $400,000 and $700,000. Places of performance span U.S. diplomatic posts globally, including Rwanda, Bangladesh, Congo, Benin, Myanmar, Serbia, and Norway, reflecting the worldwide scope of the original solicitation.
