Santa Leandra MTR DEP - Advanced Wastewater Treatment in Montegranaro, Italy

Santa Leandra MTR DEP is an advanced wastewater treatment plant located in Montegranaro, in the province of Fermo, Italy. The plant serves a population of 4,043 and has a designed capacity of 10,000 cubic meters per day, with an actual discharge volume of 800.37 cubic meters per day. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients and other pollutants, meeting stringent standards under the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size, the directive requires secondary treatment, but the plant's advanced level indicates it likely operates in a sensitive area or under additional local requirements. The plant's treated effluent is discharged into the local water system, which ultimately drains into the Adriatic Sea. The proximity to the coast (within 10 km) means the discharge may affect coastal water quality and marine ecosystems. The plant plays a key role in protecting the Adriatic Sea from nutrient pollution and supporting regional environmental health.

The plant discharges into a watercourse that flows into the Adriatic Sea, a semi-enclosed basin with limited water exchange, making it sensitive to nutrient enrichment. The surrounding area includes agricultural lands and coastal zones that support diverse marine life. Effective treatment at this plant helps prevent eutrophication and protects the ecological balance of the Adriatic coastal waters.
