DEP_COM_LA_BIANCA Wastewater Treatment Plant, Allumiere, Lazio, Italy

DEP_COM_LA_BIANCA is an advanced wastewater treatment plant located in the La Bianca area of Allumiere, in the Lazio region of Italy. The plant serves a small population of 500 residents and has a designed capacity of 600 cubic meters per day, with a current discharge volume of 98.98 cubic meters per day. It is situated near the Tyrrhenian coast, within 10 kilometers of the sea. As an advanced treatment facility, the plant goes beyond secondary treatment to remove nutrients and other pollutants, aligning with the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for sensitive areas. The advanced level indicates the use of tertiary processes such as filtration or disinfection. The plant operates under Italy's national implementation of EU regulations, which mandate appropriate treatment for discharges into coastal waters. The treated effluent is discharged into the local watershed, which ultimately drains into the Tyrrhenian Sea. This coastal discharge requires careful management to protect marine ecosystems, including seagrass meadows and coastal habitats. The plant's advanced treatment helps minimize nutrient loading and other impacts on the sensitive coastal environment.

The plant discharges into the local drainage network that flows to the Tyrrhenian Sea, a semi-enclosed basin with limited water exchange. The coastal waters near Allumiere support diverse marine life, including fish nurseries and benthic communities. Advanced treatment reduces the risk of eutrophication and protects water quality in this ecologically sensitive coastal zone.
