About the company

Washington Suburban Sanitary Commission, doing business as W S S C, a U.S. local government-owned utility headquartered in Laurel, Maryland, supplies water and sewer utility services to federal agencies and facilities as a prime contractor (98% of recent awards) on firm-fixed-price purchase orders and definitive contracts, competing full-and-open with no set-aside designations.

W S S C's federal contract footprint centers on providing water and sewer utility services to civilian research and administrative facilities across the National Capital Region. The utility's customer base is heavily weighted toward the Department of Health and Human Services National Institutes of Health, which accounts for 259 awards (198 under NIH Construction, 61 under NIH Office of Research Facilities Development Operations Acquisitions) with a combined potential value of $1.1 billion — representing 86% of the vendor's total combined potential value. Representative prime work includes a $78.9 million definitive contract with NIH Construction for water and lease invoicing services at the NIH campus in Bethesda, Maryland (award date November 10, 2021, completion December 31, 2026); a $6.67 million definitive contract with NASA's Goddard Space Flight Center for water and sewage services in Greenbelt, Maryland (award date July 1, 2022, completion April 30, 2032); a $720,131 definitive contract with the Nuclear Regulatory Commission for water and sewer services at two NRC facilities in Rockville, Maryland (award date September 13, 2024, completion November 30, 2029); and multiple $183,000 to $327,000 purchase orders from the National Cancer Institute for water and sewer services at the NCI Consolidated Research Lab and NCI Shady Grove Campus in Laurel, Maryland (annual awards from September 2022 through September 2026). The General Services Administration Public Buildings Service places 277 awards across multiple regional and leasing offices with a combined potential value of $84.6 million.

W S S C operates under five principal parent vehicles: an Indefinite Delivery Contract (F4964282D0104) with 259 task orders, likely the Air Force contract vehicle based on the Department of the Air Force's 282 award count; a Blanket Purchase Agreement (HHSN292200900004B) with 221 task orders and $74.5 million in combined potential value; and three General Services Administration Basic Ordering Agreements (GS11B01791, GS11B01788, GS11B01789) with 87 to 90 task orders each and combined potential values ranging from $8.1 million to $11.6 million. W S S C's category concentration reflects its core mission: 509 awards fall under PSC Utilities-Water, with secondary concentration in Utilities-Other (304 awards) and Housekeeping-Waste Treatment/Storage (155 awards); top NAICS codes are Water Supply and Irrigation Systems (284 awards), Lessors of Nonresidential Buildings (265 awards), and Regulation and Administration of Communications, Electric, Gas, and Other Utilities (258 awards).

W S S C also operates as a sub-recipient on multiple federal grant awards. The vendor received a cooperative agreement from the Office of Energy Efficiency and Renewable Energy (award date October 1, 2023, completion June 30, 2027) to develop a carbon-negative biosolids treatment process via CO2 upcycling to enhance water resource recovery facilities. W S S C is a sub-recipient under the Maryland Department of the Environment on multiple EPA-related water and sewer infrastructure grants, including lead and galvanized service line replacement projects across Prince George's County and Montgomery County (multiple sub-awards issued through June 2026) and sewer reconstruction and water main replacement initiatives throughout the WSSC service area (sub-awards issued November 2024 through June 2026). The vendor also subcontracts on biosolids treatment and bio-energy facility design and construction projects at the WSSC Piscataway Wastewater Treatment Plant, with prime grantee Maryland Department of the Environment and sub-award dates from July 2022 through November 2024.

Activity has been steady, averaging 6.4 awards per year over the past five years with ten awards in 2026 year-to-date. Six awards with ultimate completion inside the next twenty-four months carry combined potential value of $106.1 million, representing moderate recompete exposure concentrated in the NIH and GSA customer base. The vendor's $1.27 billion combined potential value across 1,302 total awards reflects a mature, federally embedded utility supplier with deep regional entrenchment in the National Capital Region and minimal subcontracting footprint (2% of recent awards).
