Overview
Poblado Ocuapan wastewater treatment plant in Ocuapan, Tabasco, Mexico, serves 5,804 people with secondary treatment and a designed capacity of 864 m³/day.
Poblado Ocuapan is a wastewater treatment plant located in Ocuapan, Huimanguillo, Tabasco, Mexico. It serves a population of approximately 5,804 residents, classifying it as a small-scale municipal facility. The plant is situated inland, about 50 km from the coast, and operates within the tropical climate of the Grijalva-Usumacinta region. The plant provides secondary treatment, which is the standard biological treatment stage required under Mexican regulations (NOM-001-SEMARNAT-1996) for municipal wastewater. With a designed capacity of 864 m³/day and a current discharge volume of 604.80 m³/day, the facility operates at roughly 70% capacity. This suggests adequate headroom for future population growth or seasonal variations. The treated effluent likely discharges into local watercourses that drain into the Grijalva River system, eventually reaching the Gulf of Mexico. The plant plays a key role in protecting downstream aquatic ecosystems and public health by reducing organic load and pathogens before release into the environment.
Environmental context
The plant's discharge enters the Grijalva River basin, which flows through the state of Tabasco into the Gulf of Mexico. This region supports diverse freshwater and estuarine habitats, including wetlands and mangroves that are critical for migratory birds and aquatic species. The secondary treatment helps mitigate nutrient pollution and oxygen depletion in downstream waters, preserving ecological balance in a tropical watershed.
