Rosamorada Wastewater Treatment Plant: Serving Nayarit, Mexico

Rosamorada wastewater treatment plant is located in the town of Rosamorada, Nayarit, Mexico. It serves a population of approximately 5,950 residents, classifying it as a small agglomeration under Mexican wastewater regulations. The plant operates with secondary treatment, which is the standard level for municipal wastewater in the region. The plant has a designed capacity of 1,468.80 volume units and currently handles a discharge volume of 777.60 units, indicating it is operating below its full capacity. As a Mexican facility, it falls under the oversight of the National Water Commission (CONAGUA), which enforces discharge standards based on the Official Mexican Standards (NOMs) for wastewater treatment. The treated effluent is discharged into local waterways that eventually drain into the Pacific Ocean. The region's hydrology supports diverse aquatic life, and proper treatment is essential to protect downstream ecosystems and coastal water quality. The plant's location within 50 km of the coast underscores its role in safeguarding marine environments.

The plant discharges into local rivers and streams that flow toward the Pacific Ocean, contributing to the coastal watershed of Nayarit. This region supports important estuarine and mangrove habitats, which are sensitive to nutrient pollution. Effective secondary treatment helps reduce organic load and protect downstream aquatic ecosystems, including fisheries and biodiversity along the Mexican Pacific coast.
