Saxchilbalte Wastewater Treatment Plant, Chanal, Chiapas, Mexico

Saxchilbalte is a wastewater treatment plant located in Chanal, a community in the state of Chiapas, Mexico. The plant serves a small population of 424 residents, reflecting its role in managing local domestic wastewater in a rural or semi-rural setting. As a secondary treatment facility, it provides biological treatment to reduce organic pollutants and suspended solids before discharge. The plant operates with a designed capacity of 86.40 cubic meters per day, matching its current discharge volume. Secondary treatment is the standard for plants of this scale under Mexican environmental regulations, which require compliance with NOM-001-SEMARNAT-1996 for wastewater discharge. The plant's capacity utilization suggests it is operating at full design capacity, indicating consistent service to the community. The treated effluent is discharged into local water bodies that eventually drain into the Grijalva River basin, a major hydrological system in southern Mexico. This basin supports diverse aquatic ecosystems and provides water for agriculture and human consumption. The plant's secondary treatment helps protect downstream water quality in this ecologically sensitive region, which includes tropical forests and wetlands that are important for biodiversity.

The plant discharges into local streams that flow into the Grijalva River basin, which ultimately reaches the Gulf of Mexico. This watershed supports a variety of aquatic life and is important for regional water supply. The surrounding Chiapas highlands feature tropical forests and karst landscapes, making water quality protection critical for maintaining ecological balance and preventing nutrient enrichment in downstream water bodies.
