ETE SEVARTIS Wastewater Treatment Plant - Agulhas Negras, Resende, Rio de Janeiro, Brazil

ETE SEVARTIS is a wastewater treatment plant located in Agulhas Negras, a district within the municipality of Resende, in the state of Rio de Janeiro, Brazil. The plant serves a population of approximately 20,507 people, placing it in the medium-agglomeration category under Brazilian sanitation standards. It is situated inland, near the Paraíba do Sul River basin, which is a major water resource for the region. As a plant serving a medium-sized community in Brazil, ETE SEVARTIS is expected to comply with national regulations such as CONAMA Resolution 430/2011 and the National Basic Sanitation Law (Law 11.445/2007). These regulations set effluent discharge standards and require appropriate treatment to protect water quality. The treated effluent from ETE SEVARTIS likely discharges into a local watercourse that feeds into the Paraíba do Sul River, one of the most important rivers in southeastern Brazil. This river flows through the states of São Paulo, Rio de Janeiro, and Minas Gerais, ultimately draining into the Atlantic Ocean near Campos dos Goytacazes. The plant plays a role in protecting the river's water quality, which supports drinking water supply, agriculture, and aquatic ecosystems downstream.

ETE SEVARTIS is located in the Paraíba do Sul River basin, a critical waterway for southeastern Brazil. The river supplies water to millions of people and supports diverse aquatic life, including migratory fish species. The plant's discharge likely enters a tributary of the Paraíba do Sul, which flows through the Paraíba Valley and eventually reaches the Atlantic Ocean. Protecting this watershed is essential for maintaining regional water quality and ecological balance.
