Josefino de Allende Wastewater Treatment Plant, Jalisco, Mexico

Josefino de Allende is a wastewater treatment plant located in the town of Josefino De Allende, within the municipality of Jesús María in the Altos Sur region of Jalisco, Mexico. The plant serves a small population of 1,680 residents, reflecting its role in a rural or semi-urban setting. It is situated inland, away from coastal areas, and operates as part of the local municipal wastewater infrastructure. The plant provides secondary treatment, which is a standard biological process that removes organic matter and suspended solids. With a designed capacity of 259.20 m³/day and a discharge volume matching that figure, the plant appears to operate at full capacity. Under Mexican regulations (NOM-001-SEMARNAT-1996 and subsequent updates), secondary treatment is required for discharges into national waters, and this plant meets that standard. The treated effluent is discharged into a local water body, likely a stream or river within the Lerma-Santiago-Pacifico basin, which ultimately drains into the Pacific Ocean. The plant's operation helps protect local water quality and supports the ecological health of the surrounding watershed, which is important for agriculture and biodiversity in the Altos Sur region.

The plant discharges into a local watercourse that is part of the Lerma-Santiago-Pacifico basin, one of Mexico's largest river systems. This basin flows through Jalisco and eventually reaches the Pacific Ocean via the Rio Grande de Santiago. The surrounding region is characterized by agricultural land and seasonal rivers, making the plant's treatment essential for preventing nutrient pollution and protecting downstream aquatic habitats that support diverse species.
