The treated effluent is discharged into local water bodies that eventually drain into the Pacific Ocean via the Nazas River basin. The surrounding region is semi-arid, making water quality management crucial for sustaining local ecosystems and agricultural uses downstream. The plant plays a key role in preventing untreated sewage from affecting the Nazas River and its associated wetlands.
Environmental context
The plant discharges into the Nazas River basin, which flows through Durango and ultimately reaches the Pacific Ocean via the Laguna de Mayran and the Rio Grande de Santiago. The region's semi-arid climate makes the river a critical water source for irrigation and wildlife. Protecting water quality in this basin supports diverse aquatic life and prevents eutrophication in downstream reservoirs.
