About the company
Schubert Diana, doing business as Omega Supply, is a woman-owned small business based in Lake Havasu City, Arizona, that supplies specialized water infrastructure equipment and oil purification systems to federal agencies as a prime contractor under women-owned small business set-asides. The company is a sole proprietorship operating exclusively in the prime role — all seven awards in the source data are prime contracts with zero subcontract work.
Omega Supply's customer footprint is highly concentrated with the Bureau of Reclamation (Department of the Interior), which accounts for six of seven awards and $1.6 million of the $1.7 million combined potential value. The single remaining award is a $64 thousand contract from the Army Corps of Engineers Engineering District Seattle. This concentration reflects Omega Supply's specialization in equipment and components for water resource management infrastructure — a narrow but strategically important niche within Interior's operations and maintenance portfolio.
The vendor's concrete capability portfolio centers on portable transformer oil purification systems, control valves, and oil purification trailers. Representative work includes a $1.163 million September 2026 purchase order from Bureau of Reclamation for nine to ten High Purity Northwest Thermo-Vac Mini-MOPS systems (portable transformer oil purification dry-out units) with delivery due October 31, 2027; a $206,703 March 2026 purchase order for 4-inch cast iron full port ball valves supporting Grand Coulee Dam operations; a $124,700 September 2023 purchase order for an oil purification trailer; and a $28,998 August 2023 purchase order for a 6-inch WPP control valve rotary 3800 series. All awards carry women-owned small business set-aside designations.
Activity has been episodic rather than sustained — one award in 2020, two in 2021, a gap through 2022, two in 2023, a gap through 2025, and two awards in 2026. Combined dollars obligated equal the combined potential value at 100%, indicating firm fixed-price purchase orders with complete funding. One award (the $1.163 million transformer oil purification system order) reaches completion within the next twenty-four months and faces recompete risk in that window.
