Nueva Esperanza El Veinte Wastewater Treatment Plant, Tabasco, Mexico

Nueva Esperanza El Veinte is a wastewater treatment plant located in the town of Nueva Esperanza, within the municipality of Tenosique, Tabasco, Mexico. The plant serves a population of 1,215 and is part of the region's municipal wastewater infrastructure, providing essential sanitation services to this small community. The plant employs secondary treatment, which is appropriate for its scale and aligns with Mexican regulatory standards (NOM-001-SEMARNAT-1996) that set discharge limits for pollutants. With a designed capacity of 259.20 cubic meters per day and a current discharge volume of 172.80 cubic meters per day, the facility operates below its full capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into local water bodies that eventually drain into the Gulf of Mexico via the Grijalva-Usumacinta river system. This region is ecologically significant, supporting diverse aquatic life and wetlands that are important for migratory birds and local fisheries. Proper treatment helps protect downstream ecosystems and water quality.

The plant discharges into the Usumacinta River basin, one of Mexico's largest and most biodiverse watersheds. The river flows northward through Tabasco and into the Gulf of Mexico, supporting extensive wetlands and floodplains that provide critical habitat for fish, reptiles, and migratory waterfowl. The region's tropical climate and seasonal flooding make effective wastewater treatment essential to prevent nutrient loading and maintain water quality in this ecologically sensitive area.
