MactUn Wastewater Treatment Plant, Mactún, Tabasco, Mexico

MactUn is a wastewater treatment plant located in the town of Mactún, within the municipality of Balancán, Tabasco, Mexico. The plant serves a population of approximately 1,225 people, making it a small-scale facility in a rural setting. The plant provides secondary treatment, which is the standard biological treatment required for municipal wastewater. With a designed capacity of 691.20 cubic meters per day and a discharge volume matching that figure, the facility operates at full capacity. In Mexico, wastewater treatment plants are regulated under the National Water Law (Ley de Aguas Nacionales) and NOM-001-SEMARNAT-1996, which sets discharge limits for pollutants. The treated effluent from MactUn likely discharges into a local watercourse that eventually flows into the Grijalva River basin, one of Mexico's major river systems. This basin drains into the Gulf of Mexico, supporting diverse aquatic ecosystems and providing water for agriculture and communities downstream.

The plant's discharge enters local waterways that are part of the Grijalva River basin, which flows northward through Tabasco and into the Gulf of Mexico. This region is ecologically significant, supporting wetlands and floodplain forests that provide habitat for fish, birds, and other wildlife. Proper treatment is essential to prevent nutrient pollution and protect downstream water quality in this sensitive tropical environment.
