The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. Secondary treatment typically involves activated sludge or similar biological methods. The plant's discharge volume is around 747 cubic meters per day, reflecting its small service area. Treated effluent from the plant is discharged into the local watershed, which drains into the Atlantic Ocean. The coastal environment of Marataízes supports diverse marine life and is important for local fisheries and tourism. Proper wastewater treatment is critical to prevent nutrient pollution and protect the region's coastal ecosystems.

The plant discharges treated wastewater into local watercourses that flow to the Atlantic Ocean near Marataízes. This coastal area supports mangroves, estuaries, and marine habitats that are sensitive to nutrient loading and pollution. Effective secondary treatment helps reduce organic and nutrient loads, safeguarding the ecological health of the downstream coastal zone.
