ETE Principal de Borda da Mata - Wastewater Treatment Plant in Borda da Mata, Minas Gerais

ETE Principal de Borda da Mata is a municipal wastewater treatment plant located in Borda da Mata, in the state of Minas Gerais, Brazil. The plant serves a population of approximately 14,033 people, classifying it as a medium-sized agglomeration under Brazilian regulatory frameworks. Brazil's wastewater treatment standards are governed by the National Environment Council (CONAMA) and state-level environmental agencies. For plants of this scale, secondary treatment is typically required to meet effluent quality standards before discharge. It operates within the regulatory context of Minas Gerais, which enforces discharge permits and monitoring requirements. The plant discharges treated wastewater into a local water body that eventually drains into the Rio Grande, a major tributary of the Paraná River basin. This basin supports diverse aquatic life and is important for regional water supply and agriculture. Proper treatment at this plant helps protect downstream water quality and ecosystem health.

The plant's treated effluent flows into local streams that are part of the Rio Grande watershed, which drains into the Paraná River basin. This basin is ecologically significant, supporting diverse fish species and providing water for irrigation and human consumption. The region's tropical climate and agricultural land use make effective wastewater treatment crucial to prevent nutrient pollution and protect downstream aquatic habitats.
