Poblado Soyataco Wastewater Treatment Plant, Soyataco, Tabasco, Mexico

Poblado Soyataco is a municipal wastewater treatment plant located in the town of Soyataco, within the municipality of Jalpa de Mendez, Tabasco, Mexico. The plant serves a population of approximately 5,933 residents and operates with secondary treatment, which is the standard level for communities of this size under Mexican water quality regulations (NOM-001-SEMARNAT). The plant's designed capacity is 864.00 cubic meters per day, and it currently treats an average daily flow of 561.60 cubic meters, indicating operational capacity below its design limit. As a secondary treatment facility, it utilizes biological processes to reduce organic matter and suspended solids before discharge. The plant is part of Mexico's national wastewater infrastructure managed by CONAGUA and local water utilities. The treated effluent is discharged into local water bodies that eventually drain into the Grijalva River basin, one of Mexico's major river systems. This basin supports diverse aquatic ecosystems and provides water for agriculture and communities downstream. The plant's operation helps protect water quality in the region, reducing pollution loads to sensitive coastal areas of the Gulf of Mexico.

The plant discharges into local streams that flow into the Grijalva River, which empties into the Gulf of Mexico via the Carmen and Machona lagoons. This watershed supports mangrove forests and estuarine habitats critical for fish and bird species. The secondary treatment helps reduce organic pollution, protecting downstream aquatic life and coastal water quality in the Gulf of Mexico.
