Lucero de Arcinas Wastewater Treatment Plant, El Lucero, Durango, Mexico

Lucero de Arcinas is a wastewater treatment plant located in El Lucero, within the municipality of Tlahualilo, Durango, Mexico. The plant serves a small population of 913 residents, reflecting its role in a rural or semi-urban community. It operates under Mexico's national water regulations, which set standards for wastewater treatment and discharge. The plant provides secondary treatment, a standard level for municipal wastewater that removes organic matter and suspended solids. With a designed capacity of 345.60 cubic meters per day and an actual discharge volume of 86.40 cubic meters per day, the plant operates well below its capacity, indicating potential for future growth or seasonal variations. Secondary treatment typically involves biological processes such as activated sludge or trickling filters. The treated effluent is discharged into the local environment, likely into an arroyo or drainage channel that eventually flows into the Nazas River basin. The Nazas River is a vital water source for the region, supporting agriculture and ecosystems in the arid landscape of northern Mexico. The plant's operation helps protect downstream water quality and public health in this water-scarce area.

The plant discharges into the Nazas River basin, which drains into the Laguna de Mayran, a shallow lake in the Chihuahuan Desert. This watershed is ecologically sensitive, supporting migratory birds and endemic species adapted to arid conditions. Proper wastewater treatment is crucial to prevent nutrient pollution and maintain water quality for agricultural and ecological uses downstream.
