Overview
Cereso el Hongo is a wastewater treatment plant serving approximately 11,044 people in Tecate, Baja California, Mexico. Located near the coast, it operates under Mexico's national water regulations.
Cereso el Hongo is a wastewater treatment facility located in Tecate, Baja California, Mexico. It serves a population of about 11,044 people, placing it in the small-to-medium agglomeration category. The plant is situated near the U.S.-Mexico border in a region characterized by semi-arid climate and proximity to the Pacific coast. As a Mexican wastewater treatment plant, Cereso el Hongo falls under the jurisdiction of the National Water Commission (CONAGUA) and must comply with the Federal Law of Waters (Ley de Aguas Nacionales) and its regulations. For a plant serving this population size, secondary treatment is typically required to meet discharge standards. The plant's coastal location means it likely faces additional scrutiny to protect marine water quality. The treated effluent from Cereso el Hongo ultimately drains into the Pacific Ocean via local arroyos and the Tijuana River basin. The coastal waters off Baja California support diverse marine life, including commercially important fish species and migratory marine mammals. Proper treatment is essential to prevent nutrient pollution and protect the region's coastal ecosystems.
Environmental context
Cereso el Hongo discharges into the Tijuana River watershed, which flows into the Pacific Ocean near the U.S.-Mexico border. The coastal zone is ecologically sensitive, supporting habitats for seabirds, marine mammals, and fish. Nutrient loading from wastewater can contribute to algal blooms and hypoxia, making effective treatment critical for maintaining water quality in this transboundary region.
