ETE PROFIPO Wastewater Treatment Plant, Joinville, Santa Catarina, Brazil

ETE PROFIPO is a municipal wastewater treatment facility located in the Profipo neighborhood of Joinville, Santa Catarina, Brazil. Serving a population of 960, the plant provides secondary treatment for the local community, contributing to the region's sanitation infrastructure. The plant operates under Brazil's national wastewater regulations, which require secondary treatment for urban agglomerations. With a discharge volume of 112.32 m³/day, the facility meets the treatment standards expected for its scale, ensuring that effluent is adequately treated before release. The treated wastewater is discharged into the local watershed, which ultimately drains into the Atlantic Ocean via the Babitonga Bay estuary. This coastal environment supports diverse aquatic life and is ecologically sensitive, making the plant's secondary treatment crucial for protecting downstream water quality and marine habitats.

The plant's effluent enters the local drainage network, flowing into the Cubatão River and then into Babitonga Bay, a large estuarine system on the Atlantic coast of Santa Catarina. This bay is an important nursery for fish and crustaceans and supports mangrove ecosystems. The plant's coastal proximity (within 10 km) means its discharge can directly influence the bay's water quality and ecological health.
