Overview
La Morita wastewater treatment plant serves Tijuana, Baja California, Mexico, with a population equivalent of 97,837. Located near the US-Mexico border, it discharges into the Tijuana River watershed, which flows into the Pacific Ocean.
La Morita is a wastewater treatment plant located in Tijuana, Baja California, Mexico, serving a population of approximately 97,837. The plant is situated in the Zona Río district, near the Tijuana River, and operates within the broader Tijuana metropolitan area, a major urban center on the US-Mexico border. As a plant serving a medium-to-large agglomeration, La Morita is subject to Mexico's national water quality standards (NOM-001-SEMARNAT) and the binational framework of the International Boundary and Water Commission (IBWC). Plants of this scale in Mexico typically employ secondary treatment or higher to meet discharge limits for organic matter and suspended solids. The treated effluent from La Morita ultimately reaches the Tijuana River, which flows northwest into the Tijuana River Estuary and then into the Pacific Ocean. This coastal discharge area is ecologically sensitive, supporting diverse aquatic life and migratory bird species. The plant plays a key role in protecting downstream water quality in the Tijuana River Valley and the adjacent coastal zone.
Environmental context
La Morita discharges into the Tijuana River, which flows through the Tijuana River Valley and into the Tijuana River Estuary before reaching the Pacific Ocean. This coastal watershed supports a variety of habitats, including wetlands and riparian zones, and is an important corridor for migratory birds. The estuary is a critical ecosystem that provides nursery grounds for fish and other marine life, making effective wastewater treatment essential for maintaining water quality and ecological health.
