Hazen And Sawyer, D.p.c.

Hazen And Sawyer, D.p.c. (doing business as Hazen & Sawyer PC) is a for-profit environmental and water resource engineering firm based in New York, New York, that delivers water modeling, hydrologic analysis, desalination technology development, and infrastructure advisory services to federal agencies as a prime contractor (89% of recent awards) and occasionally as a subcontractor. The firm competes full-and-open; no set-asides characterize its footprint.

Hazen & Sawyer's capability portfolio centers on specialized water resource management and treatment technologies. Recent prime work includes a $2.49 million Millennium Challenge Corporation BPA call for technical advisory services on sanitation infrastructure development in Timor-Leste (February 2022, running through February 2027), a $1.82 million Army Corps of Engineers firm fixed-price definitive contract for Task 2 water resource services with a March 2029 completion date, a $389.8 thousand U.S. Geological Survey purchase order to develop the OASIS water modeling application for the Mobile and Perdido River basins (awarded July 2022, with most recent modification exercised July 2025), and a $1.025 million Federal Energy Regulatory Commission purchase order for flood hydrology consulting services with performance in Washington, DC (awarded October 2026, extending through March 2031). The firm also holds two Bureau of Reclamation cooperative agreements focused on advanced water treatment: a larger grant award (amount not specified) on reverse osmosis optimization using machine learning and process automation (cooperative agreement, June 2023, completing December 2025), and a $202.8 thousand SECURE Water Act cooperative agreement (CFDA 15.560) to pilot electrochemical oxidation for PFAS destruction from desalination facilities (May 2023 through December 2024).

Customer concentration reflects international development and civilian water infrastructure dominance. The Millennium Challenge Corporation leads with seven awards totaling $10.2 million, representing 45% of combined potential value. The Army Corps of Engineers Engineering District Baltimore follows with four awards valued at $7.2 million. The Department of the Interior's Bureau of Reclamation and U.S. Geological Survey, along with NASA and the Federal Energy Regulatory Commission, round out the active customer set. The vendor serves twelve distinct federal agencies overall.

Hazen & Sawyer places most task orders under the Water, Sanitation & Irrigation Infrastructure Consulting BPA (six task orders, $10.2 million combined potential value), with two Army Corps of Engineers IDIQs (W912DR09D0049 and DACA5186C0052) as secondary vehicles. Activity has been modest but consistent: one award in 2021, two in 2022, three in 2023, two in 2024, and one in 2026. Only one award (the Millennium Challenge Corporation BPA call valued at $2.5 million) faces ultimate completion inside the next twenty-four months, limiting near-term recompete exposure. In its subcontractor role, Hazen & Sawyer delivers hydrological analysis and water treatment facility support to HDR Engineering and Environmental Management & Planning Solutions on Corps of Engineers and Colorado River management projects. Service Contract Inventory data shows minimal federal services footprint captured above the $150,000 reporting threshold, with fewer than 1.0 FTE across three sub-contract records (FY2022–FY2025), indicating the vendor's primary federal activity flows through prime contracts and grants rather than large SCI-reportable service engagements.
