Centenario Wastewater Treatment Plant, Gómez Palacio, Durango, Mexico

Centenario is a municipal wastewater treatment plant located in Gómez Palacio, Durango, Mexico. It serves a population of 6,389 people, making it a small-scale facility within the region's water management infrastructure. The plant provides secondary treatment, which is the standard biological treatment required under Mexican regulations (NOM-001-SEMARNAT-1996) for municipal wastewater. With a designed capacity of 864.00 m³/day and an average discharge volume of 604.80 m³/day, the plant operates below its full capacity, indicating potential for future growth or variable inflow. The treated effluent is discharged into the local environment, contributing to the protection of water resources in the arid region of Durango. The plant plays a key role in reducing pollution loads before water reaches downstream water bodies, supporting both public health and ecological balance in the Nazas River basin.

The plant discharges into the Nazas River basin, which flows through the arid landscape of northern Mexico. The Nazas River eventually drains into the Laguna de Mayran, an important wetland ecosystem that supports diverse aquatic life and migratory birds. Proper wastewater treatment is critical to prevent nutrient pollution and maintain water quality in this sensitive downstream environment.
