San Jose de La Boca Wastewater Treatment Plant, Los Pinos, Durango, Mexico

San Jose de La Boca is a municipal wastewater treatment plant located in Los Pinos, within the municipality of Tepehuanes, Durango, Mexico. The plant serves a small population of 437 residents, reflecting its role in a rural community. It operates under Mexico's national water regulations, which mandate treatment standards for discharges into the environment. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 69.12 m³/day and a current discharge volume of 64.80 m³/day, it operates near its intended capacity. As a small-scale facility, it aligns with typical infrastructure for rural agglomerations in Mexico, where treatment objectives focus on protecting local water resources. The treated effluent is discharged into a local watercourse, ultimately contributing to the broader drainage network of the region. Durango's semi-arid climate makes water quality management critical for sustaining downstream ecosystems and community water supplies. The plant's operation supports the health of nearby rivers and the overall watershed balance.

The plant discharges into a local watercourse that feeds into the broader drainage system of the Sierra Madre Occidental region. This watershed supports diverse aquatic life and provides water for agriculture and communities downstream. The semi-arid climate means that maintaining water quality is essential for ecosystem health and human use, particularly during dry seasons when dilution capacity is limited.
