The Department of Defense, through the Naval Facilities Engineering Command Marianas, intends to award a sole-source contract to the Guam Waterworks Authority (GWA) for the provision of water and sewer services on Guam. This procurement is necessary as GWA is the only legally mandated utility provider on the island, responsible for supplying potable water and wastewater services to both civilian and military customers, including key installations such as Naval Base Guam and Andersen Air Force Base. The importance of this contract lies in GWA's unique position as the sole provider capable of meeting the water and wastewater needs of areas that cannot be fully served by Department of War utilities. Interested parties may submit inquiries regarding this notice within 14 days to the primary contact, Yun Hong, at yun.p.hong.civ@us.navy.mil.
