ETE Jardim Petrópolis - Petrolina, Pernambuco Wastewater Treatment Plant

ETE Jardim Petrópolis is a wastewater treatment plant located in the Jardim Petrópolis neighborhood of Petrolina, in the state of Pernambuco, Brazil. It serves a population of approximately 4,332 residents, making it a small-scale facility within the municipal wastewater infrastructure of Petrolina. As a plant in Brazil, it is subject to the country's environmental regulations, including CONAMA resolutions and state-level permitting. For a facility of this size, secondary treatment is typically required to meet effluent standards before discharge. The plant discharges treated wastewater into the local watershed, which ultimately drains into the São Francisco River, one of Brazil's major waterways. The São Francisco River supports diverse aquatic ecosystems and provides water for agriculture, industry, and drinking water downstream. Proper treatment at this plant helps protect water quality in the river and its tributaries.

The plant's treated effluent enters the local drainage network, which flows into the São Francisco River basin. The São Francisco River is a critical water resource in northeastern Brazil, supporting irrigation, hydropower, and biodiversity. Downstream, the river discharges into the Atlantic Ocean near the border of Alagoas and Sergipe. The region's semi-arid climate makes water quality management especially important for maintaining ecological balance and human use.
