ETE Guanady Wastewater Treatment Plant, Aquidauana, Mato Grosso do Sul

ETE Guanady is a wastewater treatment plant located in the Guanandy neighborhood of Aquidauana, in the state of Mato Grosso do Sul, Brazil. The plant serves a population of about 4,987 residents, placing it in the small agglomeration category under Brazilian regulatory frameworks. Brazil's wastewater treatment standards are governed by CONAMA resolutions and state-level environmental agencies. For plants of this scale, secondary treatment is typically required to meet effluent quality standards before discharge. The plant discharges treated wastewater into local water bodies that ultimately drain into the Paraguay River basin, part of the larger Paraná River system. This region is ecologically significant, supporting diverse aquatic life and wetlands that are important for biodiversity and water quality regulation.

The plant's effluent enters local streams that flow into the Paraguay River, a major tributary of the Paraná River system. The Paraguay River basin supports extensive wetlands, including the Pantanal, one of the world's largest tropical wetlands. These ecosystems provide critical habitat for fish, birds, and other wildlife, and play a key role in flood control and water purification.
