Leona Vicario Wastewater Treatment Plant, Durango, Mexico

Leona Vicario is a wastewater treatment plant located in Leona Vicario, San Juan del Río, Durango, Mexico. It serves a small population of 456 residents, reflecting its role in a rural or small community setting. The plant operates under Mexico's national water regulations, which require secondary treatment for municipal wastewater to protect public health and the environment. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 60.48 cubic meters per day and an actual discharge volume of 43.20 cubic meters per day, it operates below its full capacity. This suggests the plant is adequately sized for current demand. The treated effluent is discharged into local water bodies, contributing to the hydrology of the region. Durango's watersheds ultimately drain into the Pacific Ocean via rivers such as the Nazas or Aguanaval. The plant's operation helps maintain water quality in these downstream ecosystems, supporting aquatic life and local water resources.

The plant discharges into local streams that are part of the Nazas-Aguanaval basin, which flows into the Pacific Ocean. This semi-arid region relies on careful water management to sustain agriculture and natural habitats. The secondary treatment reduces organic pollution, protecting downstream water quality and biodiversity.
