La Ribera Wastewater Treatment Plant - Baja California Sur, Mexico

La Ribera wastewater treatment plant is located in the town of La Ribera, within the municipality of Los Cabos in Baja California Sur, Mexico. The plant serves a population of approximately 2,998 residents, providing secondary treatment for municipal wastewater. It is situated in a coastal region, less than 10 kilometers from the Sea of Cortez. The plant has a designed capacity of 483.84 cubic meters per day and currently discharges 302.40 cubic meters per day. As a secondary treatment facility, it meets the basic treatment standards expected for a community of this size in Mexico. Mexican wastewater regulations (NOM-001-SEMARNAT-1996) set discharge limits for conventional pollutants, and plants of this scale typically require secondary treatment to comply. The treated effluent likely discharges into local arroyos or directly into the Sea of Cortez, given the plant's proximity to the coast. The Sea of Cortez is a biodiverse marine ecosystem supporting numerous fish species, marine mammals, and migratory birds. Proper treatment is essential to protect water quality and marine life in this ecologically sensitive area.

The plant is located within 10 km of the Sea of Cortez, a highly productive marine ecosystem known for its rich biodiversity. The Sea of Cortez supports a wide range of species including sea turtles, whales, and commercially important fish. Treated wastewater from the plant likely reaches the sea via local drainage, making effective treatment critical to prevent nutrient pollution and protect coastal habitats. The region's arid climate means limited freshwater dilution, so maintaining treatment standards is essential for downstream ecological health.
