Under Mexico's federal water law (Ley de Aguas Nacionales) and NOM-001-SEMARNAT-1996, wastewater treatment plants of this scale are required to meet specific discharge standards to protect water quality. The plant's designed capacity is 1. Mexican regulations typically mandate secondary or advanced treatment for plants serving over 50,000 people, especially in sensitive areas. The plant discharges into local watercourses that eventually flow into the Pacific Ocean via the Coatán River or nearby coastal lagoons. This region is ecologically important, supporting diverse aquatic life and agricultural activities. Proper treatment is essential to prevent nutrient pollution and protect downstream ecosystems.
Environmental context
The plant's treated effluent likely enters the Coatán River basin, which drains into the Pacific Ocean near the Soconusco region. This coastal area supports mangrove ecosystems and is a critical habitat for migratory birds and marine species. The region's high rainfall and agricultural runoff make effective wastewater treatment crucial for maintaining water quality in downstream rivers and coastal waters.
