TALAFOFO DISTRICT WWTF - Yona Municipality, Guam Wastewater Treatment Plant

TALAFOFO DISTRICT WWTF is a municipal wastewater treatment facility located in Yona Municipality, Guam, United States. The plant serves a population of approximately 3,999 residents, classifying it as a small agglomeration under U.S. regulatory frameworks. It is situated in a coastal area on the Pacific island of Guam, which influences its operational and environmental considerations. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater before discharge. Its designed capacity is 2,271.24 megaliters, with an actual discharge volume of 946.35 megaliters, indicating it operates below capacity. As a U.S. facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Guam Environmental Protection Agency, ensuring compliance with effluent limits. The treated effluent is discharged into the Pacific Ocean, given the plant's proximity to the coast. This discharge affects the marine environment, including coral reefs and coastal ecosystems that support diverse aquatic life. The plant plays a key role in protecting Guam's coastal waters from untreated wastewater, contributing to the health of the surrounding marine habitats.

The plant discharges into the Pacific Ocean, which surrounds Guam and is part of the larger Philippine Sea. The coastal waters support coral reef ecosystems, which are sensitive to nutrient pollution and require careful management of wastewater discharges. The plant's secondary treatment helps reduce organic load and protect marine biodiversity in this tropical island environment.
