Overview
ETE Canasvieiras serves 10,750 residents in Florianópolis, Santa Catarina, Brazil. The plant operates under Brazil's national wastewater regulations, discharging treated effluent into the Atlantic coastal environment.
ETE Canasvieiras is a wastewater treatment plant located in the Cachoeira do Bom Jesus neighborhood of Florianópolis, on Santa Catarina Island in southern Brazil. The facility serves a population of approximately 10,750 people, classifying it as a small to medium agglomeration under Brazilian sanitation standards. Its location within 50 kilometers of the coast places it in a sensitive coastal zone where nutrient removal is often required to protect marine ecosystems. Brazil's wastewater treatment framework is governed by federal laws such as Law No. 11.445/2007 (National Basic Sanitation Policy) and CONAMA resolutions, which set discharge standards for organic matter, nutrients, and pathogens. For plants of this scale in coastal areas, secondary treatment with disinfection is typical, though specific process details for ETE Canasvieiras are not part of this record. The plant's designed capacity is 1.00 (likely in cubic meters per second or similar unit), indicating a modest infrastructure footprint. The treated effluent from ETE Canasvieiras ultimately reaches the Atlantic Ocean via local drainage channels and the island's coastal waters. Florianópolis is known for its beaches and lagoons, making proper wastewater treatment critical for maintaining water quality and supporting tourism and fisheries. The plant's operation helps reduce nutrient loading and pathogen discharge into the sensitive coastal ecosystem, which supports diverse marine life and is an important migratory corridor for seabirds.
Environmental context
The plant discharges into the Atlantic Ocean near Florianópolis, a coastal city on Santa Catarina Island. The receiving waters include the island's eastern beaches and the surrounding marine environment, which supports diverse aquatic life including sea turtles, fish, and seabirds. The area is part of the South Atlantic drainage basin, where nutrient pollution from untreated sewage can lead to eutrophication and algal blooms. Proper treatment at ETE Canasvieiras helps protect these coastal ecosystems and the local tourism economy.
Frequently asked questions
ETE Canasvieiras is located in the Cachoeira do Bom Jesus neighborhood of Florianópolis, Santa Catarina, Brazil. It serves the northern part of Santa Catarina Island.
The plant serves approximately 10,750 residents, classifying it as a small to medium agglomeration under Brazilian sanitation standards.
The treated effluent is discharged into local drainage channels that flow into the Atlantic Ocean near Florianópolis' eastern beaches. The plant's coastal location requires treatment to protect marine ecosystems.
The plant operates under Brazil's National Basic Sanitation Policy (Law 11.445/2007) and CONAMA resolutions, which set discharge standards for organic matter, nutrients, and pathogens. Coastal plants typically require secondary treatment with disinfection.
For small to medium agglomerations in coastal Brazil, secondary treatment (biological process) followed by disinfection is standard. This reduces biochemical oxygen demand (BOD) and pathogen levels to meet federal discharge limits.
