Jolochero Wastewater Treatment Plant, Benito Juárez, Tabasco

Jolochero wastewater treatment plant is located in the Benito Juárez area of Jolochero, within the municipality of Balancán, Tabasco, Mexico. The plant serves a population of approximately 1,669 residents, reflecting a small-scale municipal facility typical of rural communities in the region. The plant operates with secondary treatment, which is the standard level required under Mexican regulations (NOM-001-SEMARNAT-1996) for discharge into water bodies. Its designed capacity matches the current discharge volume of 345.60 units, indicating the facility is operating at full capacity. As a small agglomeration, it is subject to national wastewater standards that set limits on pollutants like biochemical oxygen demand and total suspended solids. The treated effluent is discharged into local watercourses that eventually drain into the Grijalva River basin, one of Mexico's major hydrological systems. This basin supports diverse aquatic ecosystems and provides water for agriculture and communities downstream. The plant's secondary treatment helps reduce organic pollution loads, protecting water quality in the region's rivers and wetlands.

The plant discharges into local streams that are part of the Grijalva River basin, which flows into the Gulf of Mexico. This watershed supports important aquatic habitats, including floodplain wetlands and mangrove forests near the coast. The secondary treatment process helps mitigate nutrient and organic pollution, safeguarding downstream ecosystems that are ecologically sensitive and support fisheries and biodiversity.
