Tenejapa Wastewater Treatment Plant, Chiapas, Mexico

The Tenejapa wastewater treatment plant is located in the municipality of Tenejapa, in the state of Chiapas, Mexico. It serves a population of 4,281, providing secondary treatment to manage municipal wastewater. The plant's designed capacity and discharge volume are both 405.22, indicating it operates at full capacity. As a secondary treatment facility, Tenejapa meets the standard level of treatment required for municipal wastewater in Mexico, which typically involves biological processes to reduce organic matter and suspended solids. The plant operates under Mexico's national water regulations, which set effluent quality standards for discharges into water bodies. The treated effluent from Tenejapa is discharged into local watercourses that drain into the Grijalva River basin, one of the most important hydrological systems in southern Mexico. This basin supports diverse aquatic life and provides water for agriculture and communities downstream. The plant plays a key role in protecting local water quality and the ecological health of the region.

Tenejapa lies in the highlands of Chiapas, within the Grijalva River basin. The treated wastewater eventually flows into the Grijalva River, which empties into the Gulf of Mexico. This watershed supports a variety of ecosystems, including tropical forests and wetlands, and is home to numerous fish and bird species. Proper treatment helps prevent nutrient pollution and protects downstream water quality.
