Scale Prevention in Sewage Collection, Holding and Transfer (CHT) and Vacuum CHT (VCHT) Piping Systems for Use on Naval Surface Ships

The Naval Sea Systems Command (NAVSEA) is in the process of drafting a new specification titled MIL-PRF-XX409, focused on scale prevention in sewage collection, holding, and transfer (CHT) systems, including vacuum CHT (VCHT) piping systems used on naval surface ships. This effort aims to create standards that accommodate various design solutions and processes, thereby encouraging a wider range of vendors to participate. The initiative is open for review and comment, with interested parties invited to request a copy by contacting a specified individual via email. It is important to note that this draft is not a solicitation for bids or proposals. The contract announcement, posted on January 27, 2006, does not specify contract type, set-aside status, NAICS code, or detailed location data. Its primary purpose is to inform stakeholders of the draft specifications and to solicit feedback to ensure the final standard meets operational needs while promoting vendor diversity. This action is part of NAVSEA’s ongoing efforts to improve the reliability and maintenance of sewage systems on naval ships by reducing scaling issues that affect performance and longevity.
