DP09800601_BREMBIO Wastewater Treatment Plant, Brembio, Lombardy

DP09800601_BREMBIO is an advanced wastewater treatment plant located in Brembio, a municipality in the province of Lodi, Lombardy, Italy. The plant serves a population of approximately 2,816 residents and has a designed capacity of 2,000 m³/day, with a current discharge volume of 557.47 m³/day. As an advanced treatment facility, the plant goes beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. In Italy, wastewater treatment plants are regulated under national legislation that implements the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size (under 10,000 population equivalent), the directive requires appropriate treatment, and advanced treatment is often employed in sensitive areas to protect water quality. The plant discharges treated wastewater into local watercourses that eventually drain into the Po River basin, which flows into the Adriatic Sea. By providing advanced treatment, the plant helps protect the ecological health of the Po River and its tributaries, supporting biodiversity and water quality in one of Italy's most important agricultural and industrial regions.

The plant's treated effluent enters the local drainage network within the Po River basin, one of Italy's largest and most ecologically significant watersheds. The Po River flows eastward through the Po Valley and discharges into the Adriatic Sea, supporting diverse aquatic life and providing water for agriculture and industry. Advanced treatment at this plant reduces nutrient loads, helping to prevent eutrophication in downstream water bodies and the Adriatic Sea.
