Tecominoacan Wastewater Treatment Plant, Tecominoacán, Tabasco, Mexico

The Tecominoacan wastewater treatment plant is located in Tecominoacán, Huimanguillo, Tabasco, Mexico. It serves a population of 3,147 and operates with secondary treatment, a standard level for small communities in Mexico under NOM-001-SEMARNAT-1996 regulations. The plant has a designed capacity of 864.00 m³/day and currently discharges 604.80 m³/day of treated wastewater. As a secondary treatment facility, Tecominoacan removes organic matter and suspended solids, meeting Mexican discharge standards for inland water bodies. The plant's capacity utilization is approximately 70%, indicating operational efficiency. Mexican regulations require secondary treatment for populations over 2,500, and this plant complies with that requirement. The treated effluent is discharged into local watercourses that drain into the Grijalva River basin, one of Mexico's largest hydrological systems. The Grijalva River flows through Tabasco and ultimately reaches the Gulf of Mexico. The plant plays a key role in protecting downstream aquatic ecosystems and water quality in the region.

The plant discharges into the Grijalva River basin, which flows through the state of Tabasco and empties into the Gulf of Mexico. This watershed supports diverse aquatic life and is important for local fisheries and agriculture. The secondary treatment reduces organic pollution, helping to maintain water quality in the river and its downstream coastal environment.
