ETE ZOONOSES Wastewater Treatment Plant, Piracicaba, São Paulo

ETE ZOONOSES is a wastewater treatment plant located in Piracicaba, within the state of São Paulo, Brazil. It serves a small population of 116 residents, reflecting its role in a localized community. The plant operates under Brazil's national environmental regulations, which set standards for effluent quality and water resource protection. The plant provides secondary treatment, a standard level that removes organic matter and suspended solids. Secondary treatment is typical for small-scale facilities in Brazil. The plant discharges 26.00 cubic meters of treated wastewater, indicating a modest operational scale. Treated effluent from ETE ZOONOSES likely enters local watercourses that drain into the Piracicaba River, a tributary of the Tietê River, which flows through São Paulo state. The Tietê River ultimately reaches the Paraná River basin, supporting diverse aquatic ecosystems and regional water supplies. Protecting these waters is vital for downstream communities and biodiversity.

The plant's discharge contributes to the Piracicaba River watershed, part of the larger Tietê River basin. The Tietê River flows across São Paulo state and into the Paraná River, which drains to the Río de la Plata estuary. This watershed supports agricultural, industrial, and urban water uses, as well as aquatic habitats. Effective treatment at ETE ZOONOSES helps maintain water quality in this ecologically and economically important system.
