Chiapilla Wastewater Treatment Plant, Chiapas, Mexico

The Chiapilla wastewater treatment plant is located in the town of Chiapilla, in the state of Chiapas, Mexico. It serves a population of 1,752 residents, making it a small-scale municipal facility. The plant operates under Mexico's national water regulations, which require secondary treatment for communities of this size. The plant provides secondary treatment, which typically involves biological processes to remove organic matter and suspended solids. Its designed capacity is 552.96 cubic meters per day, and it currently discharges 165.89 cubic meters of treated wastewater daily. The facility is part of Mexico's efforts to improve sanitation in rural and semi-urban areas. The treated effluent is discharged into local waterways that drain into the Grijalva River basin, an important hydrological system in southern Mexico. This basin supports diverse aquatic life and provides water for agriculture and communities downstream. Proper treatment helps protect water quality in the region.

The plant's treated wastewater enters local streams that flow into the Grijalva River system, which ultimately reaches the Gulf of Mexico. The Grijalva basin is ecologically significant, supporting a variety of fish and bird species. Effective secondary treatment reduces organic pollution and helps maintain the health of downstream aquatic habitats.
