ETE LAGOA DO ZEZA - Secondary Wastewater Treatment Plant in Fortaleza, Ceará

ETE LAGOA DO ZEZA is a wastewater treatment plant located in the Jardim das Oliveiras neighborhood of Fortaleza, in the state of Ceará, Brazil. The plant serves a small population of 728 residents, reflecting its role in local sanitation infrastructure within the broader Fortaleza metropolitan region. The plant provides secondary treatment, which is the standard biological treatment process required for municipal wastewater in Brazil under national regulations. With a discharge volume of 104.70 units, the facility operates as part of the municipal wastewater system managed by local authorities. Brazilian treatment plants of this scale typically follow the guidelines set by the National Environment Council (CONAMA) and state environmental agencies. The treated effluent from ETE LAGOA DO ZEZA is discharged into the local watershed, which ultimately drains into the Atlantic Ocean. The plant's proximity to the coast (within 10 km) means its discharge can affect coastal water quality and marine ecosystems. Proper treatment is essential to protect the recreational and ecological value of nearby beaches and estuarine areas.

The plant discharges into the coastal watershed of Fortaleza, which flows into the Atlantic Ocean via small rivers and drainage channels. The receiving waters support diverse aquatic life and are used for recreation, making nutrient and pathogen removal critical. The region's semi-arid climate means water resources are limited, so maintaining effluent quality is important for downstream ecological health and human use.
