ETE Santa Teresa - Advanced Wastewater Treatment Plant in Santa Teresa, Espírito Santo, Brazil

ETE Santa Teresa is an advanced wastewater treatment facility located in Santa Teresa, a municipality in the state of Espírito Santo, Brazil. The plant serves a population of 8,972 residents, providing essential sanitation services to the community. Situated in the mountainous interior of the state, the plant plays a key role in managing wastewater from this small urban agglomeration. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. This level of treatment is typical for facilities discharging into sensitive environments. The plant's discharge volume of 777.60 cubic meters per day indicates its operational scale. Under Brazilian regulations, such plants are subject to federal environmental standards (CONAMA resolutions) and state-level permits. The treated effluent from ETE Santa Teresa is discharged into local watercourses that eventually drain into the Atlantic Ocean via the Doce River basin or coastal rivers of Espírito Santo. The advanced treatment helps protect downstream aquatic ecosystems, including rivers that support diverse fish populations and provide water for agriculture and human consumption. The plant's inland location reduces direct marine impact, but its discharge contributes to the overall health of the regional watershed.

The plant discharges into the tributaries of the Doce River basin, which flows eastward to the Atlantic Ocean. This watershed supports diverse aquatic life, including migratory fish species, and provides water for local communities. Advanced treatment at ETE Santa Teresa helps minimize nutrient loading and protects downstream water quality in this ecologically sensitive region.
