Overview
ARRESTRA wastewater treatment plant serves Cogoleto, Liguria, Italy, with a designed capacity of 1.00 and a population equivalent of 6,000. It is located within 50 km of the coast, discharging into the Ligurian Sea.
ARRESTRA is a wastewater treatment plant located in Punta Arrestra, Cogoleto, in the Liguria region of Italy. It serves a population equivalent of approximately 6,000, placing it in the small agglomeration category under Italian and EU regulations. As a facility in Italy, ARRESTRA operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size discharging into coastal waters. The plant's proximity to the coast (within 50 km) means it must meet stringent standards to protect marine environments. While specific treatment level data is absent, regulatory compliance would typically involve biological treatment and possibly disinfection. The plant's receiving water body is the Ligurian Sea, part of the Mediterranean Sea. This coastal area supports diverse marine life and is important for tourism and fisheries. Effective treatment is essential to prevent nutrient pollution and protect water quality in this ecologically sensitive region.
Environmental context
The ARRESTRA plant discharges into the Ligurian Sea, a basin of the Mediterranean Sea. This coastal zone supports diverse marine ecosystems, including seagrass meadows and fish nurseries, and is a popular tourist destination. Nutrient loading from wastewater could contribute to eutrophication, so treatment standards are critical for preserving water quality and biodiversity in this region.
