ETE MANTENA Wastewater Treatment Plant, Mantena, Minas Gerais, Brazil

ETE MANTENA is a wastewater treatment plant located in Mantena, a municipality in the state of Minas Gerais, Brazil. The plant serves a population of approximately 14,811 people, making it a medium-sized facility within the region's sanitation network. It is situated in the southeastern region of Brazil, an area characterized by a tropical climate and diverse ecosystems. As a plant serving a population of this scale, ETE MANTENA is expected to comply with Brazilian federal regulations, including CONAMA Resolution 430/2011 and the National Basic Sanitation Plan (PLANSAB), which set standards for effluent quality and treatment. Typical plants of this size in Brazil employ secondary treatment technologies such as activated sludge or stabilization ponds to meet regulatory requirements. The plant's treated effluent likely discharges into a local watercourse, contributing to the Rio Doce basin, which ultimately flows into the Atlantic Ocean. The Rio Doce basin is ecologically significant, supporting diverse aquatic life and providing water for communities downstream. Proper treatment at ETE MANTENA helps protect water quality in this important watershed.

ETE MANTENA discharges into a local tributary within the Rio Doce basin, which flows eastward to the Atlantic Ocean. The Rio Doce watershed supports diverse aquatic ecosystems, including fish species and riparian vegetation. Downstream, the river passes through urban and agricultural areas before reaching the coast, making effective wastewater treatment critical for maintaining water quality and ecological health.
