ETE Vicente de Carvalho - Wastewater Treatment Plant in Guarujá, São Paulo, Brazil

ETE Vicente de Carvalho is a wastewater treatment plant located in the Vicente de Carvalho district of Guarujá, in the state of São Paulo, Brazil. The plant serves a population of around 45,000 residents, contributing to the sanitation infrastructure of the Baixada Santista metropolitan region, which includes the port city of Santos. The facility is situated near the coast, highlighting its role in managing wastewater in a densely populated coastal area. Under Brazilian regulations, wastewater treatment plants of this scale are typically required to meet secondary treatment standards as per CONAMA resolutions, aiming to reduce organic load and pathogens before discharge. The plant's proximity to the coast suggests that effluent management is critical to protect marine and estuarine environments. The treated effluent from ETE Vicente de Carvalho ultimately drains into the Santos Estuary and the Atlantic Ocean, via the complex network of rivers and channels in the Baixada Santista lowlands. This region supports important mangrove ecosystems and is a key area for fisheries and tourism. The plant's operation is essential for maintaining water quality in the estuary and coastal waters, which are under pressure from urban and industrial activities.

The plant discharges into the Santos Estuary, which connects to the Atlantic Ocean. This estuarine system supports diverse aquatic life, including mangroves and fish species, and is an important migratory corridor for birds. The region's coastal waters are used for recreation and fishing, making effective wastewater treatment crucial for public health and ecosystem integrity.
