Ciudad Morelos Wastewater Treatment Plant | Baja California, Mexico

The Ciudad Morelos wastewater treatment plant is located in the town of Ciudad Morelos (Cuervos), within the municipality of Mexicali in Baja California, Mexico. The plant serves a population of approximately 2,054 residents, making it a small-scale facility in a rural or peri-urban setting. Its location near the US-Mexico border places it within a region characterized by arid climate and agricultural activity. As a Mexican wastewater treatment plant, it operates under the national regulatory framework established by the Ley de Aguas Nacionales and the Normas Oficiales Mexicanas (NOMs), particularly NOM-001-SEMARNAT-1996 which sets maximum permissible limits for pollutants in wastewater discharges. For small agglomerations like this, secondary treatment is typically expected to protect receiving water bodies. The regulatory context suggests that basic treatment standards apply. The plant discharges into the local watershed, which is part of the Colorado River basin. The Colorado River flows into the Gulf of California (Sea of Cortez), an ecologically significant marine environment that supports diverse aquatic life and important fisheries. The plant's operations contribute to protecting downstream water quality in this arid region where water resources are scarce.

The plant is located in the Colorado River basin, which drains into the Gulf of California (Sea of Cortez). This terminal estuary is a highly productive ecosystem supporting diverse marine life, including endangered species like the vaquita porpoise and totoaba fish. The arid climate and water scarcity in the region make effective wastewater treatment critical for maintaining water quality in the river and downstream coastal waters.
