Rivera Alta is a wastewater treatment plant located in Nacajuca, Tabasco, Mexico, along the Carretera Jalpa-Nacajuca. It serves a population of approximately 36,509 people, placing it in the medium-agglomeration category. 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-1996, wastewater treatment plants serving populations over 2,500 are required to meet specific discharge standards. For a plant of this scale, secondary treatment is typically expected to reduce organic matter and suspended solids. The regulatory framework ensures compliance with national water quality objectives. The treated effluent likely discharges into local watercourses that drain into the Grijalva River basin, one of Mexico's largest river systems. This basin ultimately flows into the Gulf of Mexico via the Grijalva-Usumacinta delta, a critical ecological region supporting diverse aquatic life and mangrove forests. The plant plays a key role in protecting downstream water quality and public health.
Environmental context
The plant is located in the Grijalva River basin, which drains into the Gulf of Mexico through the Grijalva-Usumacinta delta. This delta is an ecologically sensitive area that supports diverse aquatic life, including fish and crustaceans, and provides important habitat for migratory birds. The region's tropical climate and flat terrain make it prone to flooding, emphasizing the need for effective wastewater treatment to prevent nutrient and pathogen pollution in downstream waters.
