About Schubert Diana
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 maintenance parts to federal agencies as a prime contractor under woman-owned small business set-asides. The company is SBA-certified as a Women-Owned Small Business, self-certified as a small disadvantaged business, and DOT-certified as a DBE. All six of Omega Supply's recent federal awards are prime contracts; the vendor does not subcontract.
Omega Supply's customer footprint is highly concentrated. The Bureau of Reclamation (Department of the Interior) accounts for five of six awards and $484 thousand of the combined $548 thousand in potential value; the Army Corps of Engineers' Seattle Engineering District placed a single $64 thousand award. The vendor operates exclusively under woman-owned small business set-asides.
Omega Supply's capability portfolio centers on equipment procurement for water infrastructure operations and maintenance. Representative awards include a $206,703 firm fixed-price purchase order from the Bureau of Reclamation (March 2026) for 4-inch cast iron full port ball valves to support Grand Coulee Dam operations, meeting ANSI B16.10 and 200-pound working oxygen gas pressure specifications; a $124,700 order (September 2023) for an oil purification trailer supporting Reclamation projects across the Western United States; and a $28,998 order (August 2023) for a 6-inch WPP Control Valve Rotary 3800 Series. The vendor also delivered specialized analytical equipment and control valves to Reclamation projects in prior years.
Activity is sporadic. The source shows one award in 2020, two in 2021, two in 2023, and one in 2026, with all six awards now obligated at their ceiling value. No recompete cliff is present in the data — the most recent award closed out in May 2026. The vendor has no presence on government-wide vehicles or blanket purchase agreements and does not operate as a subcontractor to larger primes.
