Vicente Guerrero Wastewater Treatment Plant, Centla, Tabasco, Mexico

The Vicente Guerrero wastewater treatment plant is located in the town of Vicente Guerrero, within the municipality of Centla, Tabasco, Mexico. It serves a population of approximately 14,367 residents, classifying it as a medium-sized agglomeration under Mexican wastewater regulations. As a plant in Mexico, Vicente Guerrero operates under the national water quality standards set by the Comisión Nacional del Agua (CONAGUA), which mandates treatment levels based on population and receiving water body sensitivity. For a community of this size, secondary treatment is typically required to meet discharge standards. The plant's proximity to the coast (within 50 km) suggests that effluent may eventually reach marine environments, necessitating compliance with additional discharge criteria. The plant's treated wastewater likely discharges into local watercourses that flow toward the Gulf of Mexico, given its location in the Grijalva-Usumacinta delta region. This area supports diverse aquatic ecosystems, including mangrove forests and coastal lagoons, which are sensitive to nutrient loading and pollutants. Proper treatment is essential to protect these habitats and the livelihoods of local communities dependent on fishing and tourism.

The plant is situated in the Grijalva-Usumacinta delta, one of Mexico's most important hydrological systems. Treated effluent likely flows through local streams and canals into the Grijalva River or directly into coastal lagoons before reaching the Gulf of Mexico. This region hosts critical mangrove ecosystems that provide nursery habitat for fish and crustaceans, and support migratory bird populations. Nutrient and pathogen removal is crucial to prevent eutrophication and protect public health in downstream communities.
