Mayaguez Regional WWTP is a municipal wastewater treatment facility serving the city of Mayagüez on the western coast of Puerto Rico. With a population served of approximately 114,939, it is classified as a large agglomeration under regulatory frameworks. The plant is situated in the Sabanetas area, near the Caribbean Sea. As a facility in a U. S. territory, the plant operates under the Clean Water Act and is subject to EPA National Pollutant Discharge Elimination System (NPDES) permits. For a plant of this scale, secondary treatment is typically required, and more advanced treatment may be mandated if discharging into sensitive waters. The designed capacity is reported as 1.00 (likely in million gallons per day or similar unit), indicating a substantial infrastructure. The plant's discharge ultimately reaches the Caribbean Sea, contributing to the marine environment of the Mona Passage. The surrounding watershed includes rivers and estuaries that support diverse aquatic life. Proper treatment is critical to protect coastal ecosystems and recreational waters in the region.
Environmental context
The plant's treated effluent flows into local waterways that drain into the Caribbean Sea near the Mona Passage. This coastal region supports coral reefs, seagrass beds, and mangrove forests, which are sensitive to nutrient pollution and require effective wastewater treatment to maintain water quality and biodiversity.
