Overview
Ochitocal 1era is a secondary wastewater treatment plant in Tacotalpa, Tabasco, Mexico, serving approximately 1,825 people with a discharge volume of 172.80 cubic meters per day.
Ochitocal 1era is a wastewater treatment plant located in Tacotalpa, within the state of Tabasco, Mexico. It serves a small community of about 1,825 residents, reflecting its role in managing domestic wastewater for a rural or peri-urban area. The plant is situated in the tropical lowlands of southeastern Mexico, a region characterized by high rainfall and extensive river networks. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. With a designed capacity of 259.20 cubic meters per day and a current discharge volume of 172.80 cubic meters per day, it operates below its maximum capacity. Under Mexican regulations (NOM-001-SEMARNAT-1996 and subsequent updates), secondary treatment is typically required for discharges into water bodies to meet quality standards for parameters like biochemical oxygen demand and total suspended solids. The treated effluent is discharged into local watercourses that eventually drain into the Grijalva River basin, one of Mexico's major hydrological systems. This basin flows northward to the Gulf of Mexico, supporting diverse aquatic ecosystems and providing water for agriculture and communities downstream. The plant's operation helps protect these waters from untreated sewage, contributing to public health and environmental quality in the region.
Environmental context
The plant discharges into local streams that are part of the Grijalva River basin, which flows through Tabasco into the Gulf of Mexico. This watershed supports tropical wetlands and mangrove forests along the coast, which are critical for fish nurseries and migratory birds. The secondary treatment reduces organic pollution, helping to maintain water quality in these ecologically sensitive downstream habitats.
