Ejido Pochitocal is a wastewater treatment plant located in Tacotalpa, within the state of Tabasco, Mexico. It serves a small community of approximately 1,955 people, reflecting its role in rural sanitation infrastructure. The plant is situated inland, away from coastal zones, and contributes to local water management in the region. The facility employs secondary treatment, a standard biological process that removes organic matter and suspended solids. With a design capacity of 259.20 m³/day and an actual discharge volume of 207.36 m³/day, the plant operates at about 80% capacity. This level of treatment meets the requirements for small agglomerations under Mexican water quality regulations, which mandate secondary treatment for discharges into inland water bodies. The treated effluent is discharged into local waterways that eventually drain into the Grijalva River basin, a major hydrological system in southeastern Mexico. This river system flows into the Gulf of Mexico, supporting diverse aquatic ecosystems and providing water for agriculture and communities downstream. Proper treatment helps protect these waters from nutrient pollution and pathogens.
Environmental context
The plant discharges into the Grijalva River basin, which flows through Tabasco and into the Gulf of Mexico. This watershed supports important wetland ecosystems and fisheries. The secondary treatment reduces organic load and suspended solids, helping to maintain water quality in the river and its downstream environments, which are ecologically sensitive areas for aquatic biodiversity.
