Overview
ETE LAGO SANTA ROSA is a wastewater treatment plant serving Monte Azul Paulista, São Paulo, Brazil. It treats wastewater for approximately 6,076 residents, supporting local sanitation infrastructure.
ETE LAGO SANTA ROSA is a wastewater treatment plant located in Monte Azul Paulista, a municipality in the state of São Paulo, Brazil. The plant serves a population of around 6,076 people, making it a small-scale facility within the region's sanitation network. It is situated inland, away from coastal areas, and operates under Brazil's national environmental regulations. As a small agglomeration, the plant is expected to meet secondary treatment standards under Brazilian Resolution CONAMA 430/2011, which sets effluent quality parameters for wastewater discharges. Typical facilities of this scale employ biological treatment systems such as activated sludge or stabilization ponds to reduce organic load and pathogens before discharge. The treated effluent is likely discharged into a local watercourse that drains into the Rio Grande basin, part of the Paraná River system. This river network ultimately flows into the Río de la Plata estuary, supporting diverse aquatic ecosystems and agricultural water use downstream. Proper treatment at ETE LAGO SANTA ROSA helps protect these water bodies from nutrient pollution and pathogens.
Environmental context
The plant discharges into local streams that feed into the Rio Grande, a major tributary of the Paraná River system. The Paraná River flows through southeastern Brazil and into the Río de la Plata estuary, supporting extensive wetlands and fisheries. The region's watershed is ecologically sensitive, with seasonal rainfall patterns influencing water quality. Effective treatment at this plant helps prevent eutrophication and safeguards downstream aquatic habitats.
Frequently asked questions
ETE LAGO SANTA ROSA is located in Monte Azul Paulista, in the state of São Paulo, Brazil. It serves the local municipality as part of the regional sanitation infrastructure.
The plant serves approximately 6,076 residents, classifying it as a small-scale wastewater treatment facility under Brazilian regulations.
The treated effluent is discharged into local watercourses that drain into the Rio Grande, a tributary of the Paraná River system. The plant's inland location suggests discharge into a river or stream.
The plant operates under Brazilian environmental regulations, primarily CONAMA Resolution 430/2011, which sets effluent standards for wastewater discharges. Facilities of this scale are typically required to meet secondary treatment levels to control organic matter and pathogens.
For small agglomerations in Brazil, common treatment technologies include activated sludge systems, stabilization ponds, or anaerobic reactors followed by post-treatment. These processes aim to reduce biochemical oxygen demand (BOD) and total suspended solids (TSS) to comply with national discharge standards.
