Hydro Service & Supplies, Inc.

Hydro Service & Supplies, Inc. Maryland Division, doing business as Hydro Services & Supplies Inc., is a for-profit water purification equipment manufacturer and service provider that operates as a 100% prime contractor across 289 federal awards spanning thirty-four agencies, with specialization in preventive maintenance, repair, and supply of laboratory and research water purification systems for civilian federal research institutions. The company is headquartered in Gaithersburg, Maryland, and has been registered in SAM since 2001. The parent entity is Hydro Service & Supplies Inc. (Durham, North Carolina).

Hydro Services competes predominantly full-and-open, with no subcontract footprint—all 289 awards are prime contracts. Two awards carry total small business set-asides: a $41,257.85 definitive contract with USDA's Animal and Plant Health Inspection Service (awarded September 2026) for quarterly and annual preventive maintenance of water purification systems at APHIS's National Center for Applied Plant Protection in Laurel, Maryland, running through September 2031; and a $642,385.83 definitive contract with the National Institute of Standards and Technology (awarded March 2025) for pure water system maintenance at the NIST Gaithersburg campus through June 2030. The remaining awards use no set-aside designation.

Customer concentration clusters heavily around NIH components and related federal research agencies. The top five customers by award count account for 49% of all awards: NIH Office of the Director (39 awards), NIH National Cancer Institute (35 awards), the Smithsonian Institution (33 awards), the Uniformed Services University of the Health Sciences (22 awards), and the NIH Clinical Center (12 awards). However, the top customers by potential value diverge meaningfully—the NIH Office of Logistics and Acquisition Operations anchors $10 million in potential value across four awards, reflecting a single-award blanket purchase agreement established April 1, 2024, through April 30, 2027, for water purification systems and supplies with no stated ceiling. NIST ranks second at $2.1 million across nine awards; USU follows at $1.2 million; and the NIH National Cancer Institute rounds out the top five at $419 thousand. Combined, these five customer accounts represent 74% of combined potential value. The largest single definitive contract is the $1.868 million NIH NIEHS award (January 1, 2026, through June 30, 2031) for maintenance and repair of 196 point-of-use laboratory water purification systems and six reverse osmosis systems at Research Triangle Park, North Carolina, with on-site regenerate capability.

Parent vehicles are predominantly single-award or agency-specific BPAs. The three highest-volume vehicles are BPA HHSN263200000053273B (21 task orders, $164 thousand combined potential value), BPA HHSN263201500080B (20 task orders, $165 thousand combined potential value), and BPA HU000117AJV28 (19 task orders, $232 thousand combined potential value)—all NIH umbrella vehicles. The NIH Office of Logistics and Acquisition Operations BPA and the NIST IDC (single-award, $268,020, established June 1, 2024) together represent the largest dollar concentration on parent vehicles. Hydro Services also holds a $253,665 indefinite delivery contract with NIST (awarded June 2024, completed November 2024) for ultra-pure water system preventive maintenance at the Gaithersburg campus Building 215.

Activity has been uneven: nine awards in 2022, six in 2023, thirteen in 2024, four in 2025, and two as of September 2026. Only two awards face ultimate completion within the next twenty-four months, with combined potential value of $120 thousand, exposing minimal recompete cliff risk in the near term.

Capability portfolio is narrowly scoped to laboratory and research water purification infrastructure. Representative work includes deionized water system maintenance, reverse osmosis equipment preventive maintenance and repair, ultra-pure water system servicing, and supply of consumables including activated carbon filters, brine tank salt, DI cartridges, UV bulbs, and post-filters. Services span installation, emergency repair, system relocation, water quality validation to CAP Type 1 standards, and compliance documentation. NAICS concentration reflects this specialization: 86 awards fall under "Other Electronic and Precision Equipment Repair and Maintenance," and the top PSC codes are "Maint/Repair/Rebuild Of Equipment—Instruments And Laboratory Equipment" (103 awards) and "Water Purification Equipment" (39 awards). Work locations include multiple NIH campuses in Bethesda and Montgomery Village, Maryland; NIST Gaithersburg; USDA facilities in Laurel and Beltsville, Maryland; FDA North Bethesda; and overseas NIH facilities at Research Triangle Park, North Carolina. Combined obligated dollars total $5.9 million against $19.2 million combined potential value (31% drawdown), reflecting primarily small maintenance and supply task orders rather than large-scale infrastructure programs.
