Overview
ETE Terra Nova Varzea Grande is a secondary treatment plant serving 1,100 people in Varzea Grande, Mato Grosso, Brazil. It discharges 100.40 cubic meters of treated wastewater into local waterways.
ETE Terra Nova Varzea Grande is a municipal wastewater treatment facility located in the Condominio Terra Nova area of Varzea Grande, Mato Grosso, Brazil. The plant serves a population of approximately 1,100 residents within the Cuiaba River Valley Metropolitan Region, an area characterized by tropical savanna climate and proximity to the Pantanal wetlands. The plant provides secondary treatment, which is the standard biological treatment stage that removes organic matter and suspended solids. Under Brazilian regulations (CONAMA resolutions and the National Water Resources Policy), secondary treatment is the minimum requirement for municipal wastewater before discharge into surface waters. The plant's discharge volume is reported at 100.40 cubic meters, reflecting its small-scale operation. The treated effluent from the plant ultimately flows into the Cuiaba River, a major tributary of the Paraguay River, which drains into the Pantanal, one of the world's largest tropical wetlands. The Pantanal is an ecologically sensitive region supporting diverse aquatic life and migratory bird populations. Proper wastewater treatment at this plant helps protect downstream water quality in this globally significant ecosystem.
Environmental context
The plant discharges into the Cuiaba River basin, which flows into the Paraguay River and eventually the Pantanal wetlands. The Pantanal is a vast floodplain ecosystem that supports high biodiversity, including jaguars, capybaras, and numerous fish species. Secondary treatment reduces organic pollution and nutrient loads, helping to prevent eutrophication and maintain water quality in this sensitive downstream environment.
