Torreon de Cañas Wastewater Treatment Plant - Durango, Mexico

Torreon de Cañas is a wastewater treatment plant located in the town of Torreón de Cañas, within the municipality of Ocampo, Durango, Mexico. The facility serves a small population of 873 residents, providing essential sanitation services for this rural community in northern Mexico. The plant employs secondary treatment, which is appropriate for its scale. It has a designed capacity of 198.72 m³/day and currently discharges 164.16 m³/day of treated effluent. As a Mexican facility, it operates under the federal water pollution control framework administered by CONAGUA (National Water Commission), which sets discharge standards for municipal wastewater. The treated effluent likely drains into local arroyos or seasonal streams that feed into the Nazas River basin, part of the endorheic Bolsón de Mapimí region. This area supports semi-arid ecosystems and agricultural activities downstream, making proper wastewater treatment important for protecting local water resources and public health.

The plant discharges into the Nazas River basin, which flows through the semi-arid Bolsón de Mapimí region before terminating in the Laguna de Mayrán, an endorheic lake. This watershed supports limited but ecologically important riparian habitats and is used for irrigation. Proper treatment helps prevent nutrient loading and pathogen contamination in this water-stressed environment.
