Reyes Hdz 1ra Seccion Wastewater Treatment Plant, Tabasco, Mexico

Reyes Hdz 1ra Seccion is a wastewater treatment plant located in León Zárate Primera Sección, within the municipality of Comalcalco, Tabasco, Mexico. The plant serves a small community of 2,738 people, providing secondary treatment to manage local wastewater. The plant operates with secondary treatment, which is appropriate for its scale. In Mexico, wastewater treatment plants are regulated under the National Water Law (Ley de Aguas Nacionales) and NOM-001-SEMARNAT-1996, which sets discharge limits for pollutants. For small agglomerations like this, secondary treatment is typically sufficient to meet environmental standards. The treated effluent is discharged into local water bodies, likely tributaries of the Grijalva River system, which flows into the Gulf of Mexico. The plant plays a key role in protecting the region's aquatic ecosystems and public health by reducing organic pollutants and pathogens before discharge.

The plant discharges into the Grijalva River basin, which drains into the Gulf of Mexico. This watershed supports diverse aquatic life and is important for local fisheries. The region's tropical climate and proximity to coastal wetlands make proper wastewater treatment critical to prevent eutrophication and protect downstream ecosystems.
