About this agency
The Department of the Army Corps of Engineers Washington Aqueduct is an Army sub-agency that procures supplies, services, and construction support to operate and maintain water infrastructure serving the Washington, D.C. region. The Aqueduct has issued 268 federal contract awards since 2004, with combined potential value of $86.6 million and $81.2 million obligated to date. Recent activity has accelerated markedly: the agency issued 3 awards in 2022, 8 in 2023, 15 in 2024, 43 in 2025, and 28 year-to-date in 2026, signaling a sustained increase in procurement volume.
Among the 133 distinct prime contractors awarded over the last five years, competitive concentration is fragmented by award count and by potential value. By award count, W.w. Grainger, Inc. leads with 15 awards worth $478 thousand in combined potential value, followed by Hach Company with 10 awards ($384 thousand) and Fisher Scientific Company L.L.C. with 7 awards ($243 thousand); these three primes account for 38 percent of recent awards. By potential value, the top five primes capture only 31 percent of combined potential value, with W.m. Schlosser Co., Inc. dominating at $21.3 million across a single award, Ah Environmental Consultants, LLC at $2.2 million across 2 awards, and Suffolk Sales And Service Corporation at $1.8 million across 2 awards. The divergence between by-count and by-value concentration reflects a purchasing pattern combining high-volume, low-dollar transactions for lab supplies and equipment (Grainger, Hach, Fisher Scientific) with episodic large engineering and construction procurements.
The portfolio is heavily weighted toward unrestricted competition: 195 awards (73 percent) carry no set-aside designation. Small Business awards comprise 24 percent of the portfolio (65 awards), while 8(a) and other socioeconomic set-asides together account for less than 3 percent of awards. This mix reflects the agency's reliance on established commercial suppliers for routine operational goods and services rather than reserved or sole-source procurement.
No recent contract opportunities are present in the source material, precluding identification of current open solicitations at the Aqueduct.
