Overview
DP01203601_CASALE_LITTA is an advanced wastewater treatment plant in Villadosia, Casale Litta, Lombardy, Italy. It serves a population of 2,390 with a designed capacity of 2,500 m³/day.
DP01203601_CASALE_LITTA is an advanced wastewater treatment plant located in Villadosia, a locality within the municipality of Casale Litta in the province of Varese, Lombardy, Italy. The plant serves a population equivalent of 2,390 and has a designed capacity of 2,500 cubic meters per day, with an average discharge volume of 473.14 m³/day. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), Italy requires appropriate treatment for discharges to sensitive areas, and advanced treatment is typical for plants serving agglomerations of this size in sensitive catchments. The treated effluent is discharged into local watercourses that ultimately drain into the Po River basin and the Adriatic Sea. The plant plays a key role in protecting the region's water resources and supporting the ecological health of downstream environments.
Environmental context
The plant discharges into the local hydrographic network within the Po River basin, which flows eastward into the Adriatic Sea. The Po basin is a densely populated and agriculturally intensive region, making nutrient removal critical to prevent eutrophication in the Adriatic. The plant's advanced treatment helps reduce nitrogen and phosphorus loads, supporting water quality in downstream rivers and coastal zones.
Frequently asked questions
The plant is located in Villadosia, a locality in the municipality of Casale Litta, in the province of Varese, Lombardy, Italy.
The plant serves a population equivalent of 2,390, making it a small agglomeration under EU classification.
The treated effluent is discharged into local watercourses that are part of the Po River basin, eventually reaching the Adriatic Sea.
As an Italian plant serving a small agglomeration, it must comply with the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment based on the sensitivity of the receiving waters. The plant's advanced treatment exceeds the minimum secondary treatment requirement.
For small agglomerations in Italy, secondary treatment is standard, but advanced treatment is often required in sensitive areas to protect water quality. This plant's advanced treatment indicates it likely discharges into a sensitive catchment.
