Suchiapa Wastewater Treatment Plant, Chiapas, Mexico

The Suchiapa wastewater treatment plant is located in the municipality of Suchiapa, Chiapas, Mexico. It serves a population of approximately 4,381 residents, providing secondary treatment to municipal wastewater. The plant has a designed capacity of 1,384.13 cubic meters per day and currently discharges 414.72 cubic meters daily. As a secondary treatment facility, Suchiapa reduces organic matter and suspended solids before discharge. In Mexico, wastewater treatment plants are regulated under the Federal Water Rights Law (Ley de Aguas Nacionales) and NOM-001-SEMARNAT-1996, which sets maximum permissible limits for pollutants in treated wastewater. Plants of this scale are expected to meet these standards to protect public health and the environment. The treated effluent is discharged into local waterways that drain into the Grijalva River basin, one of Mexico's most significant hydrological systems. The Grijalva River flows through Chiapas and Tabasco before emptying into the Gulf of Mexico. This watershed supports diverse aquatic life and provides water for agriculture and communities downstream. Proper treatment at Suchiapa helps maintain water quality in this ecologically important region.

The plant's treated effluent enters local streams that are part of the Grijalva River basin, which drains into the Gulf of Mexico. The Grijalva watershed is ecologically significant, supporting diverse freshwater species and providing critical habitat for migratory birds. Downstream, the river flows through wetlands and coastal zones that are important for fisheries and biodiversity. Effective wastewater treatment helps prevent nutrient pollution and protects these sensitive ecosystems.
