Overview
DP01607901_COLOGNO_AL_SERIO is a wastewater treatment plant serving Cologno al Serio, Lombardy, Italy. It handles a population equivalent of approximately 69,365 under the EU Urban Waste Water Treatment Directive.
DP01607901_COLOGNO_AL_SERIO is a wastewater treatment plant located at 17 Via Piemonte in Cologno al Serio, a town in the province of Bergamo, Lombardy, Italy. The plant serves a population equivalent of approximately 69,365, classifying it as a medium-to-large agglomeration under Italian and European regulatory frameworks. As a plant of this scale in Italy, it is expected to comply with the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary biological treatment for agglomerations above 2,000 population equivalent. For larger agglomerations in sensitive areas, tertiary treatment may be required to reduce nutrients such as nitrogen and phosphorus. The regulatory framework ensures appropriate treatment standards. The plant discharges treated wastewater into the local water system, which ultimately drains into the Serio River, a tributary of the Adda River, and then into the Po River, which flows into the Adriatic Sea. The Po River basin is the largest in Italy and supports extensive agricultural activity, making nutrient removal critical to prevent eutrophication in the Adriatic.
Environmental context
The plant's treated effluent enters the Serio River, a major watercourse in Lombardy that flows through Bergamo and Cremona before joining the Adda River. The Adda then merges with the Po River, which discharges into the Adriatic Sea. The Po River basin is a densely populated and agriculturally intensive region, where nutrient loading from wastewater can contribute to algal blooms and hypoxia in the northern Adriatic. Effective treatment at plants like this one is essential to protect downstream water quality and the ecological health of the Po Delta and Adriatic coastal zone.
Frequently asked questions
The plant is located at 17 Via Piemonte in Cologno al Serio, a town in the province of Bergamo, Lombardy, Italy.
The plant serves a population equivalent of approximately 69,365 people, classifying it as a medium-to-large agglomeration under EU regulations.
The plant discharges treated wastewater into the Serio River, which flows into the Adda River, then the Po River, and ultimately the Adriatic Sea.
As an Italian plant serving over 10,000 population equivalent, it must comply with the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment and, in sensitive areas, tertiary treatment to reduce nutrients.
For agglomerations of this size, Italian regulations typically mandate secondary biological treatment. In sensitive areas like the Po River basin, tertiary treatment for nitrogen and phosphorus removal is often required to protect the Adriatic Sea.
