Puente de Camotlán Wastewater Treatment Plant, Nayarit, Mexico

Puente de Camotlán is a wastewater treatment plant located in the municipality of La Yesca, Nayarit, Mexico. It serves a population of 3,330 and provides secondary treatment, which is the standard level for communities of this size under Mexican water quality regulations (NOM-001-SEMARNAT). The plant has a design capacity of 570.24 cubic meters per day and currently treats an average daily flow of 345.60 cubic meters, indicating it operates well within its capacity. As a secondary treatment facility, Puente de Camotlán uses biological processes to remove organic matter and suspended solids, meeting the effluent standards required for discharge into surface waters. The plant is part of Mexico's national wastewater infrastructure, which is regulated by the National Water Commission (CONAGUA) to protect water resources and public health. The treated effluent is discharged into local waterways that eventually drain into the Pacific Ocean via the Santiago River basin. The region's rivers support diverse aquatic life and are important for agriculture and local communities. Proper treatment helps prevent nutrient pollution and maintains water quality in downstream ecosystems.

The plant discharges into the Santiago River basin, which flows westward through Nayarit and Jalisco before emptying into the Pacific Ocean near San Blas. This watershed supports a variety of freshwater species and provides water for irrigation and domestic use. The downstream environment includes estuaries and coastal habitats that are ecologically sensitive, making effective wastewater treatment crucial for preventing eutrophication and protecting biodiversity.
