Tangolunda Wastewater Treatment Plant, Santa María Huatulco, Oaxaca, Mexico

Tangolunda wastewater treatment plant is situated in Santa María Huatulco, Oaxaca, Mexico, a coastal town in the state of Oaxaca. The plant serves a population equivalent of 9,169 and has a designed capacity of 1.00, indicating a small-scale facility typical of tourist-oriented communities in the region. As a Mexican wastewater treatment plant, Tangolunda operates under the national regulatory framework established by the Ley de Aguas Nacionales and NOM-001-SEMARNAT-1996, which sets discharge standards for pollutants into national waters. The plant's proximity to the Pacific coast (within 50 km) means its treated effluent likely discharges into a local watercourse that eventually reaches the ocean. The region's coastal ecosystems, including mangroves and coral reefs, are sensitive to nutrient loading and require effective treatment to prevent eutrophication and protect marine biodiversity.

Tangolunda's treated effluent likely flows into a local stream or arroyo that drains into the Pacific Ocean near Huatulco Bay. The coastal waters of Oaxaca support diverse marine life, including sea turtles and migratory fish, and are part of a broader ecosystem that includes mangrove forests and estuaries. Effective wastewater treatment is critical to prevent nutrient pollution and protect these sensitive habitats from algal blooms and oxygen depletion.
