ETE BATAGUASSU - Secondary Wastewater Treatment Plant in Bataguassu, Brazil

ETE BATAGUASSU is a municipal wastewater treatment plant located in Bataguassu, within the state of Mato Grosso do Sul, Brazil. Serving a population of 706, the plant provides secondary treatment to the community's wastewater, discharging an average volume of 333.50 cubic meters per day. As a secondary treatment facility, ETE BATAGUASSU meets the standard level of treatment required for most inland and coastal communities in Brazil. Brazilian regulations, including CONAMA resolutions, set discharge standards for biochemical oxygen demand and other parameters, which secondary treatment typically achieves. The plant's scale places it in the small-population category, where such treatment is common. The plant's treated effluent is discharged into a receiving water body near the coast, as the facility lies within 10 km of the coastline. This proximity to coastal waters means the discharge may influence local estuarine or marine ecosystems. The plant plays a role in protecting downstream water quality and supporting the environmental health of the region's aquatic habitats.

The plant discharges treated wastewater into a water body that ultimately drains to the Atlantic Ocean via the Paraná River basin. The coastal proximity means the effluent enters a sensitive interface between freshwater and marine environments, which supports diverse aquatic life including fish and crustaceans. Proper treatment helps mitigate nutrient loading and preserve water quality in these ecologically important areas.
