Huasteca 2da Seccion Wastewater Treatment Plant, Centro, Tabasco

Huasteca 2da Seccion is a wastewater treatment plant located in Centro, Tabasco, Mexico. It serves a population of approximately 5,067 people, classifying it as a small agglomeration under Mexican wastewater regulations. The plant provides secondary treatment, which is the standard level required for municipal wastewater in Mexico under the official standard NOM-001-SEMARNAT-1996. The plant has a designed capacity of 1,296 cubic meters per day and currently discharges 864 cubic meters per day, indicating it operates below its maximum capacity. As a secondary treatment facility, it removes organic matter and suspended solids through biological processes, reducing the pollutant load before discharge. The treated effluent from Huasteca 2da Seccion is discharged into local water bodies that eventually drain into the Grijalva River system, one of Mexico's major rivers flowing into the Gulf of Mexico. The plant plays a crucial role in protecting the region's aquatic ecosystems and downstream communities from untreated sewage pollution.

The plant's discharge enters the Grijalva River basin, which flows through Tabasco and into the Gulf of Mexico. This watershed supports diverse aquatic life, including fish species important for local fisheries. The Grijalva River delta is an ecologically sensitive area with wetlands that provide habitat for migratory birds and help regulate water quality. Proper treatment at Huasteca 2da Seccion helps prevent nutrient pollution and pathogen contamination in this important coastal ecosystem.
