The plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), implemented in Italy via Legislative Decree 152/2006. As a large agglomeration, it is required to provide secondary treatment and potentially tertiary treatment in sensitive areas.
For agglomerations over 150,000 population equivalent, the EU directive mandates secondary treatment, with tertiary treatment required in sensitive areas like coastal zones. Italian plants often employ activated sludge processes with nutrient removal to meet these standards.
