ETE ITAICI - Advanced Wastewater Treatment Plant in Indaiatuba, São Paulo

ETE ITAICI is an advanced wastewater treatment plant located in the Portal Itaicí neighborhood of Indaiatuba, São Paulo, Brazil. The facility serves a population of approximately 2,183 residents, making it a small-scale municipal treatment operation within the Campinas metropolitan region. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. This level of treatment is consistent with Brazil's CONAMA regulations for protecting water quality in sensitive receiving environments. The plant discharges a daily volume of 344.74 m³ of treated wastewater. The treated effluent from ETE ITAICI ultimately drains into the Capivari River basin, a tributary of the Piracicaba River, which flows into the Tietê River and eventually reaches the Paraná River basin. This waterway network supports diverse aquatic life and provides water for downstream communities and agriculture in southeastern Brazil.

The plant's discharge enters the Capivari River watershed, which flows into the Piracicaba River, a key tributary of the Tietê River. The Tietê River traverses the São Paulo state and drains into the Paraná River basin, one of South America's major river systems. This region supports diverse aquatic ecosystems and is important for regional water supply and irrigation. The advanced treatment helps protect downstream water quality in this ecologically sensitive watershed.
