Overview
Coahuayana wastewater treatment plant serves Coahuayana de Hidalgo, Michoacán, Mexico, with a population of 10,851. The facility is located within 50 km of the Pacific coast.
The Coahuayana wastewater treatment plant is located in Coahuayana de Hidalgo, Michoacán, Mexico, serving a population of approximately 10,851 residents. The plant is situated near the Pacific coast, within 50 km of the shoreline, and plays a role in managing municipal wastewater for this community in western Mexico. As a facility serving a medium agglomeration, the plant is expected to comply with Mexican wastewater regulations (NOM-001-SEMARNAT-1996 and subsequent updates), which set discharge standards for pollutants based on receiving water body type. Plants of this scale typically employ secondary treatment to meet national standards for organic matter and suspended solids removal. The treated effluent likely discharges into local watercourses that drain toward the Pacific Ocean, contributing to the health of coastal ecosystems. The region's watershed supports diverse aquatic life and agricultural activities, making proper wastewater treatment essential for protecting downstream water quality and marine habitats.
Environmental context
The plant's discharge ultimately reaches the Pacific Ocean via local rivers and streams draining the coastal region of Michoacán. The receiving waters support estuarine and marine ecosystems, including mangrove areas and coastal lagoons that provide critical habitat for fish, crustaceans, and migratory birds. Effective treatment helps prevent nutrient enrichment and pathogen contamination in these sensitive coastal environments.
