Mecatepec Wastewater Treatment Plant, Tabasco, Mexico

The Mecatepec wastewater treatment plant is located in the town of Mecatepec, within the municipality of Huimanguillo, Tabasco, Mexico. This facility serves a population of approximately 3,407 residents, reflecting its role in managing domestic wastewater for a small community in the region. The plant employs secondary treatment, which is the standard biological process for removing organic matter and suspended solids. With a designed capacity of 604.80 m³/day and a reported discharge volume of 388.80 m³/day, the facility operates below its maximum capacity. Under Mexican regulations (NOM-001-SEMARNAT-1996), secondary treatment is required for discharges into national waters, ensuring compliance with environmental standards. The treated effluent is discharged into local water bodies that ultimately drain into the Grijalva River basin, a major hydrological system in southeastern Mexico. This basin supports diverse aquatic ecosystems and provides water for agriculture and communities downstream. The plant's operation helps protect water quality in this ecologically important region.

The plant's discharge enters the Grijalva River basin, which flows through Tabasco and into the Gulf of Mexico. This watershed supports a variety of aquatic life and is critical for local fisheries and agriculture. The region's tropical climate and flat terrain make water quality management essential to prevent eutrophication and maintain ecological balance in downstream wetlands and coastal areas.
