Magnolia Plumbing, Inc.

Magnolia Plumbing, Inc. Plumbing, Water & Sewer Utility Division is a self-certified small disadvantaged business delivering specialized plumbing, wastewater, and water utility maintenance services to federal agencies exclusively as a prime contractor on small firm purchase orders with no set-aside designations in its recent awards. The company operates as a for-profit limited liability partnership based in Washington, D.C., registered in SAM.gov since April 2000, and competes full-and-open rather than under formal SBA set-aside vehicles.

Magnolia Plumbing's service portfolio centers on sewage ejector pit pumping, inspection, and cleaning; wastewater and sewage collection, hauling, and delivery; backflow preventer repairs and certification; sewer line repair and replacement; high-pressure jetting of sanitary sewer piping; and well inspection and cleanout. Concrete examples span sewage ejector pit pumping and inspection services for the Department of Interior's Office of Policy Management and Budget ($365,671 ceiling, awarded September 2022, performance through September 2027); wastewater delivery supporting Naval Surface Warfare Center Carderock Division's shipboard sewage treatment system testing ($76,125 ceiling, August 2025, with 61 documented successful deliveries since November 2022); annual preventive maintenance and pumping of sewage ejector tanks for the Defense Counterintelligence and Security Command ($157,455 ceiling, base year July 2024 through July 2025, with a one-year extension option valued at $164,964); and multiple backflow preventer repairs and certification services for the Smithsonian Institution's museum facilities ($22,885, $30,995, and other projects between 2021 and 2023).

Customer concentration is moderate and regional. The Smithsonian Institution anchors the vendor's award count at 27 awards ($537 thousand combined potential value) but does not dominate dollars; the Department of Interior's Office of Policy Management and Budget leads the potential-value ranking with three awards worth $460 thousand, while the Department of Energy's Office of Management, the Department of Veterans Affairs' Veterans Health Administration Network 5, and the Department of the Navy's Naval Sea Systems Command collectively account for the remaining top-five concentration. The top five customers account for 55% of award count and 67% of combined potential value. Recent activity is sparse — one award in 2026, three in 2025, five in 2024 — following two-award years in 2022 and 2023. Four awards with ultimate completion dates in the next twenty-four months carry combined potential value of $662 thousand and represent recompete exposure. The vendor maintains a presence on GSA's Blanket Purchase Agreement 89303019AMA000013 (two task orders, $236 thousand) and the General Services Administration's Multiple Award Schedule, but neither vehicle dominates its workload; the bulk of awards are issued as direct purchase orders.

Magnolia Plumbing operates as a prime on 98% of its awards and subcontracts on only two recorded agreements. Across SCI-reportable service contracts, the vendor reported 5.3 FTEs in FY2024 on one subcontract award. The two named sub engagements are filter replacement work ($75 filters at 10 vault locations, April-August 2024) under Emcor Government Services as prime, and plumbing services on a roads-and-grounds contract under D7, LLC. These peripheral sub arrangements do not reflect the company's core operating model — Magnolia Plumbing builds and delivers its own teams on federal work and does not function as a feeder subcontractor to larger integrators. The vendor's business model is characterized by direct customer relationships, specialized technical capability in water and wastewater facility operations, and persistent engagement with mid-Atlantic federal installations, particularly in the National Capital Region.
