ETE LAGOA ENCANTADA - Wastewater Treatment Plant in Cuiabá, Mato Grosso, Brazil

ETE LAGOA ENCANTADA is a wastewater treatment plant located in the Morada da Serra neighborhood of Cuiabá, the capital of Mato Grosso state in Brazil's Centro-Oeste region. The plant serves a population of approximately 12,890 residents, classifying it as a small to medium-sized municipal facility within the metropolitan region of Vale do Rio Cuiabá. As a Brazilian wastewater treatment plant, ETE LAGOA ENCANTADA is subject to CONAMA Resolution 430/2011 and other federal regulations that set effluent discharge standards. For agglomerations of this scale, secondary treatment is typically required to protect receiving water bodies. It operates within the regulatory framework established by the National Water Agency (ANA) and state environmental agencies. The plant discharges treated effluent into the local watershed, which drains into the Cuiabá River, a major tributary of the Paraguay River basin. This basin is part of the Pantanal, one of the world's largest tropical wetlands and a critical ecosystem for biodiversity. Proper treatment at this plant helps protect downstream water quality in the Cuiabá River and the Pantanal floodplain.

The plant's treated effluent flows into the Cuiabá River, which is part of the Paraguay River basin. This basin ultimately drains into the Pantanal, a vast tropical wetland that supports diverse aquatic life, including fish, caimans, and migratory birds. The Pantanal is ecologically sensitive, and nutrient loading from untreated or poorly treated wastewater can lead to eutrophication and habitat degradation. Effective treatment at ETE LAGOA ENCANTADA helps maintain water quality in this important downstream ecosystem.
