ETE PICOS Wastewater Treatment Plant, Picos, Piauí, Brazil

ETE PICOS is a wastewater treatment plant located in Picos, a city in the state of Piauí, Brazil. The plant serves a population of approximately 6,456 people, making it a small-scale facility within the regional sanitation network. It is situated in the Boa Vista neighborhood, addressing the wastewater needs of this community. As a small agglomeration, ETE PICOS operates under Brazil's national environmental regulations, which require appropriate treatment to protect water quality. Plants of this scale typically employ secondary treatment methods to meet effluent standards. The regulatory framework in Brazil, overseen by agencies such as the National Water Agency (ANA) and state environmental bodies, mandates compliance with discharge limits. The treated effluent from ETE PICOS is discharged into local water bodies that drain into the Parnaíba River basin, one of the major river systems in northeastern Brazil. This basin supports diverse aquatic life and provides water for agriculture and human consumption. Proper treatment at ETE PICOS helps safeguard the ecological health of the downstream environment, including the Parnaíba Delta and the Atlantic Ocean.

ETE PICOS discharges into local waterways that are part of the Parnaíba River basin, which flows northward to the Parnaíba Delta and the Atlantic Ocean. The basin supports a variety of ecosystems, including riparian forests and wetlands, and is an important migratory corridor for birds. Effective wastewater treatment is crucial to prevent nutrient pollution and protect the biodiversity of this semi-arid region.
