Washington Suburban Sanitary Commission specializes in the delivery of potable water supply and wastewater infrastructure services to federal facilities, with deep expertise in utility system operations, billing, and compliance for mission-critical government campuses. The contractor provides end-to-end water and sewer utility services, including infrastructure maintenance, metering, billing reconciliation, and regulatory reporting, tailored to the operational demands of research, administrative, and scientific facilities. Their technical proficiency lies in integrating municipal-grade utility systems with federal facility requirements, ensuring continuous service delivery under stringent environmental and safety standards, particularly in high-security or sensitive environments such as laboratories and data centers. The contractor maintains a consistent, long-term relationship with the Department of Health and Human Services, delivering utility services to National Institutes of Health campuses including the Shady Grove and Consolidated Research Lab facilities. They also serve the Nuclear Regulatory Commission with mission-critical water and sewer services at its Rockville Pike headquarters, and have supported the Smithsonian Institution, NASA’s Goddard Space Flight Center, and the National Archives with infrastructure utility management. These engagements reflect a pattern of trusted, recurring partnerships centered on reliability, regulatory adherence, and seamless integration with federal facility operations. The primary NAICS code 221310 reflects core competency in water supply and irrigation systems, with practical focus on municipal utility services for institutional and federal buildings. The contractor’s market positioning is as a regional utility provider with proven capacity to meet federal operational standards, particularly in the Mid-Atlantic region. Their work is not construction or engineering design, but rather the ongoing operation, monitoring, and billing of water and sewer infrastructure under federal contract. As a government entity structured as a public utility commission (2A), the contractor operates under state-authorized regulatory frameworks and holds no federal business certifications. Based in Laurel, Maryland, they serve as a critical regional infrastructure partner to federal agencies requiring compliant, continuous utility services without reliance on commercial third-party vendors.
