The Department of Defense, through the Naval Surface Warfare Center Carderock Division (NSWCCD), is seeking to award a firm fixed price contract for wastewater delivery services, specifically targeting Magnolia Plumbing as the sole source provider. The contract aims to facilitate the hauling of sewage to support the testing of a simulated shipboard sewage handling system, with an initial requirement of eight loads of approximately 2,500 gallons each from treatment plants in Maryland and Virginia, and an option for up to 18 additional loads. This procurement is critical for maintaining continuity in testing and ensuring compliance with health and environmental standards, as previous attempts with other vendors did not meet necessary quality requirements. Interested parties can direct inquiries to Tracy L. McDonough at tracy.l.mcdonough2.civ@us.navy.mil, with proposals due by November 12, 2024, and the contract period extending until September 2025.
