DP01308301_CREMIA Wastewater Treatment Plant, Cremia, Lombardy, Italy

DP01308301_CREMIA is an advanced wastewater treatment plant located in Rezzonico, a frazione of Cremia, in the province of Como, Lombardy, Italy. The plant serves a population of approximately 4,037 people and is designed to handle a capacity of 8,000 m³ per day, with a current discharge volume of 799.18 m³/day. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients and other pollutants, aligning with the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for sensitive areas. The plant's operation is part of Italy's implementation of the directive, which mandates appropriate treatment levels based on population equivalents and receiving water sensitivity. The plant discharges treated effluent into the local watershed, which ultimately drains into Lake Como, a major subalpine lake in Lombardy. Lake Como is a significant ecological and recreational resource, supporting diverse aquatic life and serving as a drinking water source for downstream communities. The advanced treatment helps protect the lake's water quality from eutrophication.

The plant's treated effluent flows into the local watercourse that feeds into Lake Como, a deep subalpine lake in the Po River basin. Lake Como is a sensitive ecosystem that supports endemic fish species and provides habitat for migratory birds. The advanced treatment level helps reduce nutrient loading, preventing algal blooms and maintaining the lake's oligotrophic status, which is crucial for both ecological health and tourism.
