DP01901602_CASALBUTTANO Wastewater Treatment Plant, Casalbuttano ed Uniti, Lombardy

DP01901602_CASALBUTTANO is a wastewater treatment plant located in Casalbuttano ed Uniti, a municipality in the province of Cremona, Lombardy, Italy. The plant serves a population of approximately 7,843 residents, placing it within the small agglomeration category under EU regulations. As an Italian plant, it operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The directive also mandates appropriate treatment before discharge into inland waters. The plant is expected to meet these standards. The plant discharges into the local water system, which is part of the Po River basin. The Po River flows eastward through northern Italy into the Adriatic Sea. The surrounding area is agricultural, and the plant plays a key role in protecting local waterways from nutrient pollution and maintaining water quality for downstream ecosystems.

The plant is located in the Po River basin, one of Italy's most important watersheds. Treated effluent likely enters local canals or tributaries that feed the Po River, which ultimately drains into the Adriatic Sea. The Po basin supports intensive agriculture and diverse aquatic life, making nutrient removal critical to prevent eutrophication in the Adriatic. The region's flat terrain and irrigation networks mean that water quality management is essential for both ecological health and human use.
