The plant discharges into the drainage basin of southern Sicily, with the treated effluent eventually reaching the Mediterranean Sea. This coastal region supports diverse marine life and is important for local fisheries and tourism. The secondary treatment provided helps reduce organic pollutants and suspended solids, protecting the receiving waters from eutrophication and maintaining water quality for downstream uses.
