DP01618701_ROVETTA Wastewater Treatment Plant, Cerete Basso, Lombardy

DP01618701_ROVETTA is a wastewater treatment plant located in Cerete Basso, a frazione of Rovetta in the province of Bergamo, Lombardy, Italy. The plant serves a population of approximately 5,887 people, placing it in the small-to-medium agglomeration category under EU classification. It is situated in the alpine foothills of the Bergamo Alps, within the Valle Borlezza. As an Italian plant serving fewer than 10,000 population equivalent, it falls under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment before discharge into freshwaters. Italian regulations typically mandate secondary biological treatment for plants of this size, with possible nutrient removal if the receiving water body is in a sensitive area. The plant discharges treated effluent into the local water system, likely the Torrente Borlezza, a tributary of the Serio River. The Serio flows south through the Po Valley, eventually joining the Po River, which drains into the Adriatic Sea. This watershed supports diverse aquatic life and is important for regional agriculture and biodiversity.

The plant's treated effluent enters the Torrente Borlezza, a mountain stream that flows into the Serio River. The Serio River traverses the Lombardy region and joins the Po River, which ultimately discharges into the Adriatic Sea. This watershed is ecologically sensitive, supporting fish species such as trout and grayling, and provides water for irrigation and industrial use downstream. The alpine origin of the water body means it is particularly vulnerable to nutrient enrichment, making proper treatment essential for maintaining water quality.
