SisoGuichi Wastewater Treatment Plant, Sisoguichi, Chihuahua, Mexico

SisoGuichi is a wastewater treatment plant located in the town of Sisoguichi, within the municipality of Bocoyna, Chihuahua, Mexico. It serves a small population of 913 residents, reflecting its role in a rural community in the Sierra Madre Occidental region. The plant provides primary treatment, which involves physical processes like sedimentation to remove solids. With a designed capacity of 129.60 cubic meters per day and a current discharge volume of 86.40 cubic meters per day, it operates below its design capacity. Under Mexican regulations (NOM-001-SEMARNAT-1996), primary treatment is acceptable for small communities, though higher levels may be required to protect sensitive water bodies. The treated effluent is discharged into local waterways that drain into the broader Conchos River basin, eventually reaching the Rio Grande (Rio Bravo). This watershed supports diverse aquatic life and is important for agriculture and water supply in the region. The plant's operation helps reduce pollution in this ecologically significant system.

The plant discharges into local streams that flow into the Conchos River, a major tributary of the Rio Grande (Rio Bravo). This river system supports a variety of fish species and provides water for irrigation and human use in the arid Chihuahuan Desert. The watershed is ecologically sensitive, with habitats that depend on consistent water quality. Downstream, the Rio Grande forms the border between Mexico and the United States, making pollution control critical for binational water resources.
