ETE Planeta dos Macacos - Secondary Wastewater Treatment Plant in Recife, Pernambuco, Brazil

ETE Planeta dos Macacos is a wastewater treatment plant located in the Jardim São Paulo neighborhood of Recife, Pernambuco, Brazil. The plant serves a population of 3,229 and operates with secondary treatment, which is appropriate for its small scale. Recife is a major coastal city in northeastern Brazil, and the plant is part of the municipal infrastructure managed by the local water utility. As a secondary treatment facility, ETE Planeta dos Macacos provides biological treatment to remove organic matter and suspended solids. The plant discharges 384.00 cubic meters per day of treated effluent. The plant's design aligns with Brazilian regulatory standards for small agglomerations under CONAMA resolutions and state environmental permits. The plant is located within 10 km of the Atlantic coast, making its discharge potentially influential on coastal water quality. The treated effluent likely flows into local drainage channels that reach the Atlantic Ocean via the Recife estuary system. This coastal environment supports mangroves and diverse marine life, requiring careful management of nutrient and pathogen levels to protect recreational waters and ecosystems.

The plant discharges into the Recife coastal watershed, which drains into the Atlantic Ocean via the Capibaribe and Beberibe rivers. This estuarine region supports mangroves and seagrass beds that serve as nursery habitats for fish and crustaceans. The proximity to the coast means treated effluent can affect nearshore water quality, particularly in areas used for recreation and fishing. Nutrient loading from wastewater is a key concern in this tropical coastal environment.
