Ciudad de Comalcalco Wastewater Treatment Plant, Comalcalco, Tabasco, Mexico

The Ciudad de Comalcalco wastewater treatment plant is located in Comalcalco, Tabasco, Mexico, serving a population of approximately 41,393. As a medium-sized agglomeration, the plant plays a key role in managing municipal wastewater in the region. Under Mexican regulations (NOM-001-SEMARNAT-1996 and subsequent updates), wastewater treatment plants are required to meet specific discharge standards based on the receiving water body. For plants of this scale, secondary treatment is typically expected to reduce organic matter and suspended solids. The plant's operational details are consistent with standard municipal infrastructure in Tabasco. The plant's treated effluent likely discharges into local rivers or streams that flow toward the Gulf of Mexico. The region's tropical climate and proximity to the coast mean that proper treatment is essential to protect downstream aquatic ecosystems and coastal water quality. The plant contributes to the sanitation needs of Comalcalco and helps mitigate pollution in the Grijalva River basin.

The plant is located in the Grijalva River basin, which drains into the Gulf of Mexico. The region supports diverse aquatic life, including mangrove ecosystems and coastal fisheries. Proper wastewater treatment is critical to prevent nutrient loading and protect downstream habitats, particularly in the sensitive coastal zone near the Carmen-Machona lagoon system.
