Poblado Amado Gomez Wastewater Treatment Plant, Cunduacán, Tabasco

Poblado Amado Gomez is a wastewater treatment plant located in Cunduacán, Tabasco, Mexico. The plant serves a small population of approximately 2,191 residents, providing secondary treatment for municipal wastewater. It is situated inland, away from coastal areas, and operates as part of the local water infrastructure in the Grijalva River basin. The plant provides secondary treatment, which is the standard biological treatment required for municipal wastewater. With a designed capacity of 537.41 m³/day and a current discharge volume of 207.36 m³/day, the plant operates below its full capacity. Under Mexican regulations (NOM-001-SEMARNAT-1996 and subsequent updates), secondary treatment is sufficient for inland discharge to freshwater bodies. The treated effluent is discharged into local watercourses that ultimately drain into the Grijalva River, one of Mexico's major rivers flowing into the Gulf of Mexico. The Grijalva basin supports diverse aquatic life and is ecologically significant, providing habitat for fish and migratory birds. Proper treatment helps protect downstream water quality and ecosystem health.

The plant discharges into the Grijalva River basin, which flows through Tabasco and into the Gulf of Mexico. This watershed supports important wetlands and aquatic habitats, including areas that serve as breeding grounds for fish and migratory waterfowl. The region's tropical climate and seasonal flooding make effective wastewater treatment critical to prevent nutrient pollution and protect downstream ecosystems.
