Overview
ETE GUARAI is a secondary wastewater treatment plant serving Guaraí, Tocantins, Brazil. It treats municipal wastewater for a population of 2,096 with a discharge volume of 211.57 units.
ETE GUARAI is a wastewater treatment plant located in Guaraí, Tocantins, Brazil. It serves a population of 2,096 and operates as part of the municipal sanitation infrastructure in the northern region of the country. The plant provides secondary treatment, which is the standard biological treatment required for urban wastewater under Brazilian regulations (CONAMA Resolution 430/2011 and relevant state norms). For a small agglomeration of this size, secondary treatment is appropriate to reduce organic load and suspended solids before discharge. The treated effluent is discharged into local water bodies within the Tocantins River basin, which drains into the Atlantic Ocean via the Amazon River system. The plant plays a role in protecting downstream water quality in a region characterized by tropical savanna climate and sensitive aquatic ecosystems.
Environmental context
The plant discharges into the Tocantins River basin, which flows northward to join the Amazon River delta. This watershed supports diverse aquatic life and is important for local fisheries and water supply. The region's tropical climate and seasonal rainfall patterns influence dilution and assimilation capacity of receiving waters.
