ETE Santana V Wastewater Treatment Plant, Piracicaba, São Paulo

ETE Santana V is a wastewater treatment plant located in the Santana district of Piracicaba, in the state of São Paulo, Brazil. The plant serves a small population of 465 residents, reflecting its role in a localized community within the broader Piracicaba metropolitan region. As a secondary treatment facility, it provides biological treatment to reduce organic matter and suspended solids before discharge. The plant operates under Brazil's national environmental regulations, which require wastewater treatment for urban agglomerations. For small communities like this, secondary treatment is the standard to meet water quality standards set by the National Environment Council (CONAMA). The plant's discharge volume of 104.00 m³/day indicates a modest flow consistent with its small service population. The treated effluent is released into the local watershed, which ultimately drains into the Piracicaba River, a tributary of the Tietê River. The Tietê River flows through São Paulo state and eventually reaches the Paraná River basin, one of South America's major river systems. The plant's operation helps protect downstream water quality and supports aquatic life in the region's rivers.

The plant discharges into the Piracicaba River basin, which flows into the Tietê River, a major waterway in São Paulo state. The Tietê River is ecologically significant, supporting diverse aquatic species and providing water for agriculture and urban use downstream. The plant's secondary treatment reduces organic pollution, helping to maintain the health of this important river system.
