ETE LOPES is a wastewater treatment facility located in Limeira, within the state of São Paulo, Brazil. The plant serves a population of about 2,936 residents, classifying it as a small-scale municipal treatment system. It is situated in the interior of São Paulo, away from the coast, and operates under Brazil's national environmental regulations. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. Secondary treatment typically involves activated sludge or similar biological methods. Brazil's regulatory framework, including CONAMA resolutions and state-level environmental agencies, sets discharge standards for such facilities to protect water quality. The treated effluent is discharged into local water bodies, likely tributaries of the Piracicaba River basin, which flows into the Tietê River and eventually reaches the Paraná River system. This inland drainage network supports agricultural and urban water uses downstream. The plant's operation helps reduce pollution loads in the region's freshwater resources.
Environmental context
The plant discharges into the Piracicaba River basin, a sub-basin of the Tietê River, which flows through São Paulo state and ultimately joins the Paraná River. This watershed supports diverse aquatic life and provides water for irrigation and drinking water supply. The region's subtropical climate and agricultural activity make nutrient management important to prevent eutrophication in downstream reservoirs.
