Overview
ETE Maria Leite serves Ladário, Mato Grosso do Sul, Brazil, treating wastewater for approximately 37,217 people. The plant operates under Brazil's national environmental regulations.
ETE Maria Leite is a municipal wastewater treatment plant located in Ladário, a city in the state of Mato Grosso do Sul, Brazil. The plant serves an estimated population of 37,217, placing it in the medium-sized agglomeration category for the region. Brazil's wastewater treatment standards are governed by CONAMA Resolution 430/2011 and the National Basic Sanitation Plan (Plansab), which set effluent quality requirements. For plants of this scale, secondary treatment is typically expected to meet discharge limits for organic matter and suspended solids. The plant's treated effluent ultimately flows into the Paraguay River basin, a major tributary of the Paraná River system. This watershed supports diverse aquatic ecosystems and is important for regional water supply and biodiversity in the Pantanal region, one of the world's largest tropical wetlands.
Environmental context
The Paraguay River basin receives discharges from Ladário's wastewater infrastructure. This basin drains into the Paraná River and eventually the Río de la Plata estuary. The Pantanal, a vast floodplain ecosystem downstream, is ecologically sensitive, supporting jaguars, capybaras, and migratory birds. Proper treatment is critical to prevent nutrient loading and maintain water quality in this globally significant wetland.
