Boca de Tomatlán Wastewater Treatment Plant, Jalisco, Mexico

The Boca de Tomatlán wastewater treatment plant is located in the coastal town of Boca de Tomatlán, part of Puerto Vallarta in the state of Jalisco, Mexico. It serves a small population of 913 residents, reflecting its role in a smaller community within the Costa Norte region. The plant provides secondary treatment, which is the standard biological treatment required under Mexican regulations (NOM-001-SEMARNAT) for municipal wastewater. Its designed capacity is 345.60 m³/day, and it currently discharges 86.40 m³/day of treated effluent. The plant operates under the framework of Mexico's Federal Water Law and is subject to discharge standards set by the National Water Commission (CONAGUA). The treated wastewater is discharged into the local environment, likely into the Pacific Ocean given the plant's coastal proximity. The surrounding area includes the Bahía de Banderas, a large bay known for its marine biodiversity and tourism. Proper treatment is essential to protect coastal water quality and the health of marine ecosystems.

The plant discharges into the Bahía de Banderas, a large bay on the Pacific coast of Mexico that supports diverse marine life, including sea turtles and migratory fish. The bay is an important ecological and economic resource for tourism and fisheries. Effective wastewater treatment helps prevent nutrient pollution and protect coastal water quality.
