The discharge volume of 214.27 m³/day indicates a modest operation. Under Brazilian regulations, such plants are subject to CONAMA standards and state-level environmental licensing. The treated effluent is discharged into local streams that flow into the Atibaia River, a tributary of the Piracicaba River, which eventually reaches the Tietê River basin. This watershed supports diverse aquatic life and is important for regional water supply and agriculture. The plant's operation helps protect downstream water quality in the Campinas metropolitan region.

The plant discharges into local watercourses that drain into the Atibaia River, part of the Piracicaba River basin, which flows into the Tietê River and ultimately reaches the Paraná River system. This watershed supports diverse aquatic ecosystems and is used for drinking water supply, irrigation, and recreation. The region's subtropical climate with seasonal rainfall influences runoff and dilution capacity, making consistent treatment important for maintaining ecological balance.
