Jalupa I Wastewater Treatment Plant, Jalupa, Tabasco, Mexico

Jalupa I is a municipal wastewater treatment plant located in Jalupa, a locality in the municipality of Jalpa de Mendez, Tabasco, Mexico. The plant serves a population of approximately 6,845 residents, making it a small-scale facility within the region's wastewater infrastructure. The plant provides secondary treatment, which is the standard biological treatment process that removes organic matter and suspended solids. With a designed capacity of 864.00 units and a current discharge volume of 648.00 units, the plant operates below its maximum 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 into national waters. The treated effluent from Jalupa I is discharged into local water bodies that eventually drain into the Grijalva River basin, one of Mexico's major river systems. The Grijalva River flows through Tabasco and empties into the Gulf of Mexico, supporting diverse aquatic ecosystems and providing water for agriculture and communities downstream.

Jalupa I discharges into the Grijalva River basin, which flows through the low-lying, flood-prone region of Tabasco. The river ultimately reaches the Gulf of Mexico, a marine environment that supports fisheries and coastal habitats. The plant's secondary treatment helps reduce organic pollution, but the region's high rainfall and agricultural runoff can exacerbate nutrient loading, potentially affecting downstream water quality and aquatic life.
