ETE JAPUIRA Wastewater Treatment Plant, Cuiabá, Mato Grosso

ETE JAPUIRA is a wastewater treatment plant located in the Santa Rosa neighborhood of Cuiabá, Mato Grosso, Brazil. The plant serves a small population of 124 residents, reflecting its role in local sanitation infrastructure for a limited service area. The plant employs secondary treatment, which is the standard biological process required for municipal wastewater in Brazil under national regulations. For small agglomerations like this, secondary treatment effectively reduces organic matter and suspended solids before discharge, meeting typical environmental standards. The treated effluent is discharged into local water bodies within the Cuiabá River basin, which flows into the Paraguay River and eventually the Paraná River system. This downstream network supports diverse aquatic life and is important for regional water resources and the Pantanal wetlands ecosystem.

The plant discharges into the Cuiabá River basin, part of the Paraguay River watershed that drains into the Paraná River system. This region supports ecologically sensitive areas, including the Pantanal, one of the world's largest tropical wetlands. Proper treatment helps protect downstream water quality and aquatic biodiversity.
