ETE Mundo Novo Macrófitas - Secondary Wastewater Treatment in Novo Hamburgo, Rio Grande do Sul

ETE Mundo Novo Macrófitas is a wastewater treatment plant located in the Canudos neighborhood of Novo Hamburgo, in the state of Rio Grande do Sul, Brazil. It serves a small population of 206 residents as part of the municipal sanitation infrastructure for the Porto Alegre metropolitan region. The plant provides secondary treatment, which is the standard level required under Brazilian regulations (CONAMA Resolution 430/2011) for most inland discharges. With a daily discharge volume of 69.12 m³, the facility operates at a scale typical for small communities. Treated effluent from the plant flows into local streams that are part of the Sinos River basin, which ultimately drains into the Guaíba Lake and then the Patos Lagoon, one of the largest coastal lagoons in South America. This watershed supports diverse aquatic life and provides water for downstream communities, making proper treatment essential for environmental protection.

The plant discharges into the Sinos River basin, which flows into the Guaíba Lake and then the Patos Lagoon, a major coastal lagoon system in southern Brazil. The Patos Lagoon estuary supports important fisheries and migratory bird populations. Secondary treatment helps reduce organic pollution and nutrient loads, protecting downstream water quality in this ecologically sensitive region.
