About the company
OTT Hydromet Corp, a Sterling, Virginia-based subsidiary of Veralto Corporation (formerly Danaher), manufactures and supplies hydrological and meteorological monitoring equipment to federal civilian agencies as a prime contractor across full-and-open federal procurement, with no set-aside posture. The company specializes in streamgages, water quality sensors, precipitation gauges, data loggers, satellite telemetry systems, and related instrumentation essential to nationwide water resource management and environmental data collection. OTT Hydromet competes exclusively as a prime (100% of awards); the three sub-awards in the source represent downstream pass-through relationships rather than OTT Hydromet's operating posture.
Customer concentration is extreme and reflects the vendor's role as a specialized supplier to science and water-management agencies. The top five funding agencies account for 47% of awards by count and 60% of combined potential value. The Department of the Interior's U.S. Geological Survey Office of Acquisitions and Grants dominates both metrics: 294 awards valued at $188.2 million combined potential value, anchored by a $44.95 million single-award indefinite delivery contract for hydrological equipment and repair services to the USGS Hydrologic Instrumentation Facility running through December 2029. The National Oceanic and Atmospheric Administration ranks second by dollar value with 194 awards ($33.4 million combined potential), supported by a $1.96 million single-award blanket purchase agreement for Sutron-branded environmental monitoring equipment through June 2027 and a $7.034 million indefinite delivery contract for precipitation accumulators through September 2028. The Department of the Interior's Bureau of Reclamation places 216 awards ($10.3 million combined potential); the Department of the Army Corps of Engineers, 163 awards ($2.3 million combined potential). OTT Hydromet also serves the National Park Service, U.S. Fish and Wildlife Service, USDA agencies, Environmental Protection Agency, and smaller federal science and logistics entities.
Vehicle position reflects GSA Multiple Award Schedule dominance. OTT Hydromet holds the Federal Supply Schedule contract GS25F6040D (609 task orders, $35.3 million combined potential value) and participates in the standard GSA Multiple Award Schedule (120 task orders, $17.5 million combined potential). On the customer side, the USGS indefinite delivery contract ING17PC00021 has generated 89 task orders ($15.2 million), and ING13PC00007 has generated 53 task orders ($9.4 million). Recent awards include a $1.3 million single-award indefinite delivery contract from USGS (December 2024) for maintenance and repairs of OTT Hydromet equipment through December 2029, and a $1.96 million BPA with NOAA for Sutron equipment (June 2025) through June 2027.
Activity has declined year over year from 37 awards in 2022 and 2023 to 17 awards in 2026 (through mid-September). Only five awards (combined potential value $2.7 million) complete within the next twenty-four months, reducing near-term recompete exposure. The combined potential value across all 2,042 awards stands at $399.1 million, of which $207.2 million (52%) has been obligated. By NAICS, OTT Hydromet's footprint concentrates on instrument manufacturing: 1,166 awards under NAICS 334513 (Instruments and Related Products Manufacturing for Measuring, Displaying, and Controlling Industrial Process Variables), 280 under NAICS 334519 (Other Measuring and Controlling Device Manufacturing), with smaller segments in custom programming and related services. The PSC footprint mirrors this: geophysical instruments (374 awards), combination and miscellaneous instruments (328), and liquid/gas flow measuring instruments (180) dominate.
OTT Hydromet's federal award footprint is a textbook specialized-equipment-supplier profile: non-commodity, technical equipment essential to federal water and climate missions, sole-source and competitive awards without set-asides, concentration among a handful of science and resource-management agencies, and long-term single-award vehicles that lock in supplier relationships. The vendor's parent, Veralto Corporation (formerly Danaher's Environmental and Applied Solutions segment, spun to public company status in 2023), carries a portfolio of water and environmental technology brands, positioning OTT Hydromet as a core component of that strategic footprint. Recent award velocity decline and low recompete-cliff exposure suggest a mature, stable federal position rather than aggressive expansion or near-term risk.
