ETE Pedrinhas Guaratinguetá is a wastewater treatment plant located in the Pedrinhas area of Guaratinguetá, within the Metropolitan Region of Vale do Paraíba e Litoral Norte in São Paulo, Brazil. The plant provides secondary treatment for a small population of 140 residents, reflecting its role in local sanitation infrastructure. The plant operates under Brazil's national environmental regulations, which require secondary treatment for urban wastewater. With a discharge volume of 25.92 units, the facility manages effluent from its service area. Brazilian standards, such as CONAMA resolutions, set effluent quality parameters for receiving water bodies.

This river flows through the Paraíba Valley and ultimately reaches the Atlantic Ocean near Campos dos Goytacazes. The plant helps protect downstream aquatic ecosystems and water quality.
Environmental context
The plant discharges into the Paraíba do Sul River basin, which flows through the Vale do Paraíba region and empties into the Atlantic Ocean. This watershed supports diverse aquatic life and is an important water source for multiple municipalities. The secondary treatment reduces organic load and nutrients, mitigating eutrophication risks in downstream water bodies.
