General Treviño II Wastewater Treatment Plant, General Treviño, Nuevo León, Mexico

General Treviño II is a municipal wastewater treatment plant located in General Treviño, Nuevo León, Mexico. The plant provides secondary treatment, which is the standard level required under Mexican regulations (NOM-001-SEMARNAT-1996) for municipal wastewater before discharge. This level of treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring compliance with environmental standards. The treated effluent is discharged into local water bodies, contributing to the protection of the surrounding watershed. The plant's operations help maintain water quality in the region, which ultimately drains into the Gulf of Mexico via the Rio Grande basin. This supports downstream ecosystems and water resources in northeastern Mexico.

The plant is located inland, more than 10 km from the coast, but within 50 km of the Gulf of Mexico. Its discharge likely enters the Rio Grande basin, which flows into the Gulf. The region supports diverse aquatic life and is important for migratory birds. Proper treatment helps prevent nutrient pollution and protects the sensitive coastal environment.
