Overview
ETE Jose Cirilo is a secondary treatment plant serving 6,815 people in Muriae, Minas Gerais, Brazil. It discharges 864 m3/day of treated wastewater into local water bodies.
ETE Jose Cirilo is a municipal wastewater treatment plant located in the Santana neighborhood of Muriae, a city in the Zona da Mata region of Minas Gerais, Brazil. The plant serves a population of approximately 6,815 residents, placing it in the small-to-medium agglomeration category under Brazilian regulatory frameworks. The plant provides secondary treatment, which is the minimum standard required by Brazilian environmental legislation (CONAMA resolutions) for most inland municipalities. Secondary treatment typically involves biological processes to remove organic matter and suspended solids. The treated effluent is discharged into local watercourses that ultimately drain into the Paraiba do Sul River basin, one of the most important river systems in southeastern Brazil. The Paraiba do Sul flows through industrial and agricultural regions before reaching the Atlantic Ocean near Campos dos Goytacazes. The plant's operation helps protect downstream water quality and aquatic ecosystems in this economically vital watershed.
Environmental context
The plant discharges into tributaries of the Paraiba do Sul River, which flows through Minas Gerais, Rio de Janeiro, and Sao Paulo states before emptying into the Atlantic Ocean. The Paraiba do Sul basin supports diverse aquatic life and provides water for millions of people, industry, and agriculture. Downstream areas include the Paraiba do Sul estuary, an ecologically sensitive region that serves as a nursery for fish and crustaceans. Protecting water quality in this basin is critical for maintaining regional biodiversity and water security.
