Tomochi Wastewater Treatment Plant, Chihuahua, Mexico

Tomochi wastewater treatment plant is located in the town of Tomochi, within the municipality of Guerrero, in the state of Chihuahua, Mexico. The facility serves a population of approximately 3,124 residents, providing essential sanitation services for this rural community in northern Mexico. The plant operates with secondary treatment, which is appropriate for its small scale. With a designed capacity of 432.00 cubic meters per day and a discharge volume matching that figure, the facility appears to operate at full capacity. Under Mexican regulations (NOM-001-SEMARNAT-1996 and subsequent updates), secondary treatment is required for municipal wastewater to meet discharge standards for organic matter and suspended solids. The treated effluent is discharged into local water bodies, likely tributaries of the Rio Conchos or other regional streams that drain into the Rio Grande (Rio Bravo) basin. This watershed supports agricultural activities and provides water for communities downstream. The plant's operation helps protect local water quality and public health in the region.

The plant discharges into the Rio Conchos watershed, which flows northward to join the Rio Grande (Rio Bravo) at the US-Mexico border. This river system is a critical water source for both countries, supporting irrigation, livestock, and municipal supplies. The region's semi-arid climate makes water quality management particularly important for maintaining ecosystem health and agricultural productivity.
