Overview
Santo Domingo wastewater treatment plant in Chiapas, Mexico, serves a small population of 146 with secondary treatment. It discharges 13.82 units of treated wastewater, with a designed capacity of 2246.40 units.
The Santo Domingo wastewater treatment plant is located in the town of Santo Domingo, within the municipality of Unión Juárez, in the state of Chiapas, Mexico. This facility serves a small population of 146 residents, reflecting its role in a rural or peri-urban setting. The plant is situated inland, away from coastal zones, and its operations are part of Mexico's national wastewater management infrastructure. The plant provides secondary treatment, which is a standard biological process that removes organic matter and suspended solids. Secondary treatment is the minimum requirement under Mexican regulations (NOM-001-SEMARNAT-1996) for discharges into water bodies. The designed capacity of 2246.40 units suggests the plant was built to accommodate potential future growth, while current discharge volume is 13.82 units, indicating low utilization. The treated effluent is discharged into local water bodies that eventually drain into the Pacific Ocean via the region's river systems. Chiapas is characterized by mountainous terrain and high rainfall, making water resource management critical for both human use and ecosystem health. The plant's operation helps protect downstream water quality in a region known for its biodiversity.
Environmental context
The plant discharges into local streams that are part of the Grijalva River basin, which flows into the Gulf of Mexico. This watershed supports diverse aquatic life and provides water for agriculture and communities. The region's tropical climate and steep slopes make it sensitive to erosion and nutrient runoff, so effective wastewater treatment is essential to prevent eutrophication and protect downstream ecosystems.
