ETE MUNIZ FREIRE Wastewater Treatment Plant, Muniz Freire, Espírito Santo

ETE MUNIZ FREIRE is a municipal wastewater treatment plant located in São Vicente de Paula, Muniz Freire, in the state of Espírito Santo, Brazil. The plant serves a population of approximately 5,300 residents, classifying it as a small-scale facility within the region's sanitation infrastructure. The plant employs secondary treatment, which is the standard biological process required for municipal wastewater in Brazil under national regulations. This level of treatment removes organic matter and suspended solids, producing effluent suitable for discharge into surface waters. The plant handles an average daily flow of 623.68 cubic meters, reflecting the demand of the local community. The treated effluent is discharged into the local water system, which drains into the Itapemirim River basin and eventually reaches the Atlantic Ocean. The plant plays a crucial role in protecting downstream water quality and supporting the ecological health of the region's rivers and coastal environment.

The plant discharges into the Itapemirim River basin, which flows through the mountainous terrain of Espírito Santo before reaching the Atlantic Ocean. This watershed supports diverse aquatic life and provides water for agriculture and communities downstream. The secondary treatment process helps reduce nutrient and organic pollution, mitigating eutrophication risks in the river and coastal zone.
