Fraccionamiento La Selva is a wastewater treatment plant located in Nacajuca, Tabasco, Mexico. The facility serves a population of approximately 14,604 residents, placing it in the medium agglomeration category for Mexican wastewater infrastructure. The plant is situated in the low-lying, humid tropical region of Tabasco, which is characterized by extensive river systems and wetlands. Under Mexico's federal water law (Ley de Aguas Nacionales) and NOM-001-SEMARNAT-2021 standards, municipal wastewater treatment plants of this scale are required to meet specific discharge limits for organic matter, solids, and pathogens. Typical plants in this region employ secondary treatment technologies such as activated sludge or stabilization ponds to comply with national regulations. The treated effluent from Fraccionamiento La Selva ultimately drains into the Grijalva River basin, one of Mexico's largest hydrological systems. The Grijalva River flows northward through Tabasco into the Gulf of Mexico, supporting diverse aquatic ecosystems including mangrove forests and coastal lagoons. Proper treatment is essential to protect these sensitive environments from nutrient pollution and pathogens.
Environmental context
The plant's discharge enters the Grijalva River basin, which drains into the Gulf of Mexico via the Grijalva-Usumacinta delta. This region supports extensive mangrove ecosystems and is a critical habitat for migratory birds and aquatic species. The tropical climate and flat terrain make the area susceptible to flooding, which can affect wastewater management and water quality.
