Overview
ETE Santa Maria da Serra is a secondary treatment plant serving 5,092 people in Santa Maria da Serra, São Paulo, Brazil. It discharges 432.00 cubic meters of treated wastewater daily.
ETE Santa Maria da Serra is a municipal wastewater treatment plant located in Santa Maria da Serra, a city in the state of São Paulo, Brazil. The plant serves a population of approximately 5,092 residents, classifying it as a small-scale facility within the region's sanitation infrastructure. The plant provides secondary treatment, which is the standard level required under Brazilian regulations (CONAMA resolutions) for inland water bodies. With a daily discharge volume of 432.00 cubic meters, the facility operates within the typical parameters for a community of this size. Brazilian environmental legislation mandates that treatment plants of this scale meet effluent quality standards to protect receiving waters. The treated effluent is discharged into local watercourses that ultimately drain into the Piracicaba River basin, a major tributary of the Tietê River. The Piracicaba River is an important water resource for the region, supporting agriculture, industry, and drinking water supplies downstream. The plant's secondary treatment helps reduce organic load and nutrients, contributing to the ecological health of the basin.
Environmental context
The plant discharges into the Piracicaba River basin, which flows into the Tietê River and eventually reaches the Paraná River system. This watershed supports diverse aquatic life and is a critical water source for the São Paulo region. The secondary treatment process helps mitigate nutrient pollution, which is essential for preventing eutrophication in downstream reservoirs and maintaining water quality for multiple uses.
