Benjamín Urías Ejido Revolución Wastewater Treatment Plant, Durango, Mexico

Benjamín Urías Ejido Revolución is a municipal wastewater treatment plant located in Benjamín y Urías, Hidalgo, Durango, Mexico. The facility serves a small community of 1,315 residents, providing essential sanitation infrastructure for this rural area in northern Mexico. The plant employs secondary treatment, which is appropriate for its population scale. With a designed capacity of 380.16 m³/day and an actual discharge volume of 198.72 m³/day, the plant operates below its capacity, indicating room for future growth. Under Mexican regulations (NOM-001-SEMARNAT), secondary treatment is the standard for municipal wastewater to protect water quality. The treated effluent is discharged into the local watershed, which ultimately drains into the Nazas River basin. This river system is ecologically significant in the arid region of Durango, supporting agriculture and local biodiversity. Proper treatment helps maintain water quality in this water-scarce area.

The plant discharges into the Nazas River basin, a critical water source in the semi-arid Durango region. The Nazas River flows into the Laguna de Mayrán, an endorheic lagoon that supports migratory birds and local wildlife. Effective secondary treatment is vital to prevent nutrient loading and protect this fragile downstream ecosystem.
