ETE Chapeco is a municipal wastewater treatment plant located in Chapeco, Santa Catarina, Brazil. The plant serves a population of approximately 72,494 people, placing it in the medium agglomeration category for Brazilian wastewater infrastructure. It is situated in the southern region of Brazil, an area characterized by subtropical climate and significant agricultural activity. Brazilian wastewater treatment plants of this scale are typically regulated under national environmental standards set by CONAMA (National Environment Council) and operated by municipal or state water utilities. Plants serving populations of this size commonly employ secondary treatment technologies such as activated sludge or stabilization ponds to meet effluent quality standards. The plant discharges treated wastewater into local water bodies that ultimately drain into the Uruguay River basin, which flows southward to the Rio de la Plata estuary. This watershed supports diverse aquatic ecosystems and is important for regional water supply and agriculture. Proper treatment at ETE Chapeco helps protect downstream water quality and ecological health.
Environmental context
