DP09806101_ZELO_BUON_PERSICO is a wastewater treatment plant located in Bisnate, a locality within Zelo Buon Persico, in the province of Lodi, Lombardy, Italy. The plant serves a population equivalent of 7,699, placing it in the small-to-medium agglomeration category under Italian and EU regulations. As a plant of this scale in Italy, it is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations above 2,000 population equivalent. The regulatory framework ensures compliance with national standards for effluent quality. The plant discharges treated wastewater into local watercourses that drain into the Po River basin, ultimately reaching the Adriatic Sea. The Po River is Italy's longest river and supports extensive agricultural activity and diverse aquatic ecosystems. The plant's operations contribute to protecting water quality in this important hydrological system.

The plant is located in the Po River basin, which drains a large portion of northern Italy and flows into the Adriatic Sea. The Po River and its tributaries support rich biodiversity, including fish species such as sturgeon and eel, and provide irrigation for the Po Valley, a major agricultural region. The plant's discharge affects local streams that feed into the Po, making its treatment performance critical for downstream water quality and ecosystem health.
