ETE DO AEROPORTO Wastewater Treatment Plant, Cáceres, Mato Grosso

ETE DO AEROPORTO is a municipal wastewater treatment plant located in the Aeroporto neighborhood of Cáceres, in the state of Mato Grosso, Brazil. The plant serves a population of approximately 1,021 residents, classifying it as a small-scale facility within the region's sanitation infrastructure. The plant provides secondary treatment, which is the standard biological treatment process required under Brazilian regulations (CONAMA 430/2011) for most inland wastewater systems. This level of treatment removes organic matter and suspended solids, ensuring the effluent meets basic quality standards before discharge. The plant operates with a daily discharge volume of 172.80 cubic meters. The treated effluent is released into a local watercourse that eventually drains into the Paraguay River basin, a major tributary of the Paraná River system. This watershed supports diverse aquatic life and is part of the Pantanal, one of the world's largest tropical wetlands. Proper treatment at this plant helps protect downstream ecosystems and water quality in the region.

The plant discharges into a tributary of the Paraguay River, which flows through the Pantanal region, a vast floodplain known for its rich biodiversity. The Paraguay River ultimately joins the Paraná River and drains into the Río de la Plata estuary. The Pantanal is ecologically sensitive, supporting numerous fish, bird, and mammal species, and maintaining water quality is critical for this unique wetland ecosystem.
