Overview
Colombia wastewater treatment plant in Nuevo León, Mexico, serves 554 people with secondary treatment. It discharges 172.80 cubic meters daily, operating under Mexican water quality regulations.
The Colombia wastewater treatment plant is located in the town of Colombia, within the municipality of Anáhuac, Nuevo León, Mexico. This facility serves a small population of 554 residents, providing essential sanitation services for the local community. The plant is situated in a semi-arid region near the US-Mexico border, where water resources are scarce and treatment is critical for public health and environmental protection. The plant employs secondary treatment, which is appropriate for its small scale. Under Mexican regulations (NOM-001-SEMARNAT-1996 and subsequent updates), wastewater treatment plants must meet discharge standards based on receiving water body type. For a plant of this size, secondary treatment typically achieves the required pollutant removal. The designed capacity is 864.00 cubic meters per day, with an actual discharge volume of 172.80 cubic meters per day, indicating significant spare capacity. The treated effluent is likely discharged to a local arroyo or intermittent stream that drains into the Rio Grande (Río Bravo) basin, which ultimately flows to the Gulf of Mexico. This watershed supports diverse aquatic life and is an important migratory corridor for birds. Proper treatment helps protect downstream water quality in a region where water is a precious resource.
Environmental context
The plant discharges into the Rio Grande (Río Bravo) basin, which flows through arid landscapes before reaching the Gulf of Mexico. The river supports critical habitat for fish and migratory birds, and its waters are used for irrigation and municipal supply. Effective treatment is essential to prevent nutrient pollution and maintain ecological balance in this water-stressed region.
