Miramar Wastewater Treatment Plant, Buena Vista 1ra. Secc., Tabasco

Miramar is a wastewater treatment plant located in Buena Vista 1ra. Secc., in the municipality of Centro, Tabasco, Mexico. It serves a population of approximately 9,127 people, classifying it as a small to medium-sized facility within the region's municipal wastewater infrastructure. The plant provides secondary treatment, which is the standard biological treatment level required under Mexican regulations (NOM-001-SEMARNAT-1996) for municipal wastewater before discharge. With a designed capacity of 864 m³/day and a reported discharge volume of 864 m³/day, the facility operates at full capacity, indicating consistent treatment of the incoming wastewater flow. The treated effluent is discharged into the local watershed, which ultimately drains into the Gulf of Mexico via the Grijalva River system. The plant plays a key role in protecting downstream aquatic ecosystems and coastal water quality in the Tabasco region, an area characterized by extensive wetlands and floodplains that support diverse freshwater and estuarine species.

The plant discharges into the Grijalva River basin, one of Mexico's largest river systems, which flows into the Gulf of Mexico. The downstream environment includes sensitive coastal wetlands and mangrove ecosystems that provide critical habitat for fish, crustaceans, and migratory birds. Effective wastewater treatment is essential to prevent nutrient loading and maintain water quality in these ecologically productive areas.
