Mosciano Costa del Monte Wastewater Treatment Plant, Mosciano Sant'Angelo, Abruzzo

The Mosciano Costa del Monte wastewater treatment plant is located in the Ripoli area of Mosciano Sant'Angelo, in the Abruzzo region of Italy. It serves a population of approximately 2,500 people, making it a small-scale municipal facility. The plant is situated near the Adriatic coast, within 10 km of the shoreline, which influences its environmental management priorities. As a secondary treatment facility, the plant provides biological treatment to reduce organic matter and suspended solids. With a designed capacity of 4,000 cubic meters per day and an average discharge volume of 494.91 cubic meters per day, the plant operates well below its capacity, indicating room for future growth. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), small agglomerations like this are required to have appropriate treatment, and secondary treatment meets the standard for discharges into coastal waters. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Adriatic Sea. The coastal environment supports diverse marine life and is an important ecological zone. Proper treatment helps protect water quality in the receiving waters, reducing nutrient loads and safeguarding the coastal ecosystem.

The plant discharges into the local watershed that flows to the Adriatic Sea, a semi-enclosed basin with sensitive marine ecosystems. The coastal area supports seagrass meadows and fish nurseries, which are vulnerable to nutrient pollution. Effective secondary treatment helps mitigate eutrophication risks and maintains water quality for recreational and ecological uses.
