Overview
ETE Santa Terezinha Canela serves Canela, Rio Grande do Sul, Brazil, treating wastewater for approximately 7,924 residents. The plant operates under Brazil's national water quality regulations.
ETE Santa Terezinha Canela is a municipal wastewater treatment plant located in Canela, a city in the state of Rio Grande do Sul, Brazil. Serving a population of about 7,924 people, the plant is part of the region's sanitation infrastructure managed by local authorities. Brazil's wastewater treatment facilities are regulated by the National Environment Council (CONAMA) and the Ministry of Cities, with standards for effluent quality and receiving water body protection. For plants of this scale, secondary treatment is typically required to reduce organic load and pathogens before discharge. The plant's treated effluent likely discharges into a local watercourse within the Rio Grande do Sul watershed, which ultimately drains into the Atlantic Ocean. Protecting these waterways is critical for downstream communities and ecosystems, including the Lagoa dos Patos system and coastal environments.
Environmental context
The plant's discharge enters a tributary of the Rio Caí basin, which flows into the Jacuí River and eventually reaches the Lagoa dos Patos, a large coastal lagoon connected to the Atlantic Ocean. This watershed supports diverse aquatic life and provides water for agriculture and urban use downstream. Proper treatment is essential to prevent nutrient enrichment and maintain water quality in this ecologically sensitive region.
