The U.S. Department of Agriculture (USDA) is seeking qualified small businesses to design and install a custom reverse osmosis (R.O.) system and water softener for the Central Utility Plant (CUP) at the National Bio and Agro-Defense Facility (NBAF) in Manhattan, Kansas. The contractor will be responsible for providing an engineered installation schematic and ensuring that the system meets high water quality standards necessary for research involving zoonotic and agricultural diseases. This procurement is critical for maintaining a secure environment for ongoing research activities, and the USDA aims to award a single firm fixed-price contract on a small business set-aside basis, contingent upon receiving sufficient responses from qualified small businesses. Interested parties should contact David Hildebrand at david.hildebrand@usda.gov for further details, and responses to the sources sought notice must include specific information about the firm’s capabilities and experience by the indicated deadline.
