ETE CODIN Wastewater Treatment Plant, Campos dos Goytacazes, Rio de Janeiro

ETE CODIN is a wastewater treatment plant located in Campos dos Goytacazes, in the state of Rio de Janeiro, Brazil. The plant serves a population of around 16,080 people, placing it in the small to medium agglomeration category. It is situated inland, more than 50 km from the coast, in the Região Sudeste region. As a Brazilian wastewater facility, ETE CODIN is subject to the National Environmental Council (CONAMA) resolutions and state-level environmental regulations, which set standards for effluent quality and treatment. For plants of this scale, secondary treatment is typically required to protect receiving water bodies. The plant's designed capacity is 1.00 (likely in a unit such as m³/s or L/s), indicating a modest infrastructure. The plant discharges into local watercourses that drain into the Paraíba do Sul River basin, a major river system in southeastern Brazil. This river flows into the Atlantic Ocean near São João da Barra, supporting diverse aquatic life and providing water for agriculture and urban use downstream. Proper treatment at ETE CODIN helps maintain water quality in this ecologically sensitive watershed.

ETE CODIN is located in the Paraíba do Sul River basin, which drains into the Atlantic Ocean. The river supports a variety of fish species and is an important water source for the region. The plant's effluent, after treatment, enters local streams that contribute to the river's flow, impacting downstream ecosystems and coastal waters.
