Overview
Tuxtla Gutierrez Paso Limon wastewater treatment plant serves 431,689 people in Tuxtla Gutiérrez, Chiapas, Mexico. The facility operates under Mexican water quality regulations (NOM-001-SEMARNAT-1996) for discharge standards.
Tuxtla Gutierrez Paso Limon is a wastewater treatment plant located in Tuxtla Gutiérrez, the capital city of Chiapas, Mexico. Serving a population of 431,689, the plant is a key component of the city's sanitation infrastructure, handling wastewater from residential and commercial sources. The facility is situated in the central highlands of Chiapas, a region characterized by tropical climate and significant seasonal rainfall. The plant operates under Mexico's federal water pollution control regulations, primarily NOM-001-SEMARNAT-1996, which sets maximum permissible limits for pollutants in wastewater discharges. For a plant serving over 400,000 people, advanced secondary or tertiary treatment is typically required to meet these standards. The designed capacity is 1.00 (likely in cubic meters per second or similar unit), indicating a large-scale facility. The treated effluent is discharged into the local watershed, which ultimately drains into the Grijalva River basin, one of Mexico's most important river systems. The Grijalva River flows northward through Chiapas and Tabasco, eventually reaching the Gulf of Mexico. The plant's operations help protect downstream aquatic ecosystems, including the Grijalva River's diverse fish populations and the coastal wetlands of the Gulf, from untreated sewage pollution.
Environmental context
The plant discharges into the Grijalva River basin, which drains into the Gulf of Mexico. This watershed supports diverse aquatic life, including endemic fish species and migratory birds. The region's tropical climate and seasonal rains make proper wastewater treatment critical to prevent nutrient loading and algal blooms in downstream water bodies.
