EX_ACNA_CO Wastewater Treatment Plant, Cengio, Liguria, Italy

EX_ACNA_CO is a wastewater treatment plant located in Cengio, a municipality in the province of Savona, Liguria, Italy. The plant serves a population of approximately 8,800 people, classifying it as a small to medium agglomeration under EU regulations. Its location in the Ligurian hinterland places it within the Bormida River basin, a tributary of the Tanaro River, which ultimately drains into the Po River and the Adriatic Sea. As an Italian plant serving fewer than 10,000 people, EX_ACNA_CO is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment (biological treatment) for discharges into freshwater and estuaries. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas, such as those prone to eutrophication. The plant's design capacity of 1.00 (likely in thousands of cubic meters per day) suggests it is sized appropriately for its population equivalent. The plant's treated effluent is discharged into the local water system, which flows through the Bormida River and eventually reaches the Po River, Italy's longest river. The Po River basin is ecologically significant, supporting diverse aquatic life and providing water for agriculture and industry. Downstream, the Po Delta is a critical wetland habitat for migratory birds and fish species. Proper wastewater treatment at EX_ACNA_CO helps protect these downstream ecosystems from nutrient pollution and pathogens.

EX_ACNA_CO discharges into the Bormida River, a tributary of the Tanaro River, which flows into the Po River and ultimately the Adriatic Sea. The Po River basin is one of Italy's most important ecological and economic regions, supporting agriculture, industry, and biodiversity. The downstream Po Delta is a vital wetland for migratory birds and fish. Effective treatment at this plant helps prevent eutrophication and contamination in these sensitive waters.
