Gran Morelos Wastewater Treatment Plant, San Nicolas de Carretas, Chihuahua

Gran Morelos is a wastewater treatment plant located in San Nicolas de Carretas, within the municipality of Gran Morelos, Chihuahua, Mexico. The facility serves a small population of 986 residents, reflecting its role in a rural or semi-urban community. The plant is situated inland, far from coastal areas, and operates under Mexico's national water regulations. The plant employs secondary treatment, which typically involves biological processes to reduce organic matter and suspended solids. With a designed capacity of 259.20 m³/day and a current discharge volume of 172.80 m³/day, the facility operates below its maximum capacity. For small communities like this, secondary treatment is standard under Mexican norms (NOM-001-SEMARNAT), which set discharge limits for pollutants into national waters. The treated effluent is likely discharged into a local watercourse or used for irrigation, contributing to the protection of the region's water resources. The plant's operation helps safeguard the local watershed, which is part of the larger Rio Conchos basin, a tributary of the Rio Grande (Rio Bravo). This river system supports agriculture and ecosystems in northern Mexico and the US border region.

The plant discharges into the local watershed within the Rio Conchos basin, which flows into the Rio Grande (Rio Bravo) and eventually reaches the Gulf of Mexico. This region is semi-arid, making water quality crucial for agricultural and ecological needs. The treatment plant helps reduce nutrient and pathogen loads, protecting downstream aquatic life and human water users.
