Overview
EPC CAICARA is a wastewater treatment plant in Cubatão, São Paulo, Brazil, serving approximately 10,215 people. It is located within 50 km of the coast, discharging into the local watershed.
EPC CAICARA is a wastewater treatment plant located in Cubatão, within the Baixada Santista metropolitan region of São Paulo, Brazil. The plant serves a population of about 10,215 people, placing it in the small to medium agglomeration category. It operates under Brazil's national environmental regulations, which require appropriate treatment for discharges into sensitive coastal areas. Plants of this scale in Brazil typically employ secondary treatment to meet federal discharge standards. The designed capacity is 1.00 (likely in cubic meters per second or similar unit), indicating a facility sized for the local population. Regulatory oversight is provided by state environmental agencies such as CETESB in São Paulo. The plant's discharge ultimately reaches the Atlantic Ocean via the Cubatão River and the Santos estuary. This region is ecologically sensitive, supporting mangrove ecosystems and estuarine habitats that are critical for fish and bird species. The proximity to the coast necessitates careful management to prevent nutrient loading and protect marine biodiversity.
Environmental context
EPC CAICARA discharges into the Cubatão River, which flows into the Santos estuary and then the Atlantic Ocean. The Santos estuary is a vital ecological zone, supporting mangroves and serving as a nursery for marine life. The region's coastal waters are subject to pollution pressures from industrial and urban activities, making effective wastewater treatment crucial for preserving water quality and aquatic habitats.
