Diiez de Octubre San Lucas de Ocampo Wastewater Treatment Plant, Durango, Mexico

Diiez de Octubre San Lucas de Ocampo is a municipal wastewater treatment plant located in Diez de Octubre, within the municipality of San Juan del Río, Durango, Mexico. The plant serves a population of 1,825, classifying it as a small-scale facility under Mexican water management standards. Its location in the semi-arid region of northern Mexico underscores the importance of efficient water reuse and environmental protection. The plant operates with secondary treatment, which typically involves biological processes to remove organic matter and suspended solids. Secondary treatment is the standard for communities of this size under Mexican regulations (NOM-001-SEMARNAT-1996). The plant has a designed capacity of 293.76 cubic meters per day and a discharge volume of 172.80 cubic meters per day, indicating operational activity within its capacity. The treated effluent is discharged into local water bodies, contributing to the health of the surrounding watershed. Durango's water systems ultimately drain into the Pacific Ocean via the Nazas River basin or other regional hydrologic systems. Proper treatment helps protect downstream ecosystems and supports agricultural and domestic water uses in this water-scarce region.

The plant discharges into local watercourses that are part of the Nazas River basin, which flows into the Laguna de Mayran and eventually the Pacific Ocean. This semi-arid region relies heavily on groundwater and surface water for agriculture and human consumption. Effective secondary treatment reduces organic pollution and pathogens, safeguarding aquatic life and preventing eutrophication in downstream water bodies.
