Guam Waterworks Authority

Guam Waterworks Authority, a U.S. local government entity headquartered in Tamuning, Guam, acts as a prime recipient of federal grants for water and wastewater infrastructure design, construction, and operational capacity building, with no federal contract prime awards in the recent footprint. The Authority operates exclusively as a prime grant recipient (100% of recent awards) with no subcontract role, receiving awards from the Environmental Protection Agency Region 9, the Department of the Interior's Insular Affairs and Bureau of Reclamation offices, and the Department of Defense Office of Economic Adjustment.

Guam Waterworks Authority delivers water and wastewater infrastructure projects under federal grant programs anchored in the Bipartisan Infrastructure Law and EPA state revolving fund mechanisms. Representative work includes a $32.1 million EPA Region 9 formula grant (CFDA 66.600, awarded May 1, 2026) funding construction of a Fats, Oils, and Grease receiving facility at the Northern District Wastewater Treatment Plant, Hagatna forcemain rehabilitation, general waterline replacement, booster pump installation, and dieldrin mitigation through April 30, 2033. A $28.7 million EPA cooperative agreement (CFDA 66.600, awarded October 1, 2024) funds collection line rehabilitation, waterline replacement and rehabilitation, sewer lift station and forcemain rehabilitation, and well rehabilitation through September 30, 2031. A $26.4 million EPA cooperative agreement (CFDA 66.600, awarded October 1, 2022) supported water and sewer services for the Gil Breeze subdivision, a FOG receiving station for the Northern District Wastewater Treatment Plant, hiring of four senior engineers, and Hagatna pump station and force main construction. The Authority also received a $950 thousand Department of the Interior Bureau of Reclamation WaterSMART project grant (CFDA 15.507, awarded September 5, 2024) for Santa Rita Springs facility design and upgrade to maximize spring discharge and reduce purchased water costs. Smaller awards from Department of the Interior Insular Affairs include a $296.5 thousand project grant (CFDA 15.875, awarded July 24, 2023) for subsurface water line leak detection training and equipment, a $438 thousand project grant for electric vehicle procurement (awarded September 15, 2022), and a $124 thousand technical assistance program grant (CFDA 15.875, awarded August 15, 2022) for financial management and operational capacity training delivered at industry conferences.

EPA Region 9 and Department of the Interior Insular Affairs dominate the recent award footprint, with 10 EPA awards and 11 Insular Affairs awards (combined 97% of recent activity) and $374.4 million in combined dollars obligated across all 39 awards since 2002. Activity spiked in 2022 with six awards, then declined to one to three awards annually in 2023, 2024, and 2026. Two awards face ultimate completion within the next twenty-four months. The Authority receives no sub-awards and does not sub-contract to other vendors; all work is performed as a prime grant recipient using internal staff and procurement of external construction and professional services contractors.
