IDL_VIA_SOLDAINI Wastewater Treatment Plant, Cascina, Tuscany, Italy

IDL_VIA_SOLDAINI is a wastewater treatment facility located in San Lorenzo alle Corti, a frazione of Cascina in the province of Pisa, Tuscany, Italy. The plant serves a small population of 222 people and operates at a designed capacity of 150 cubic meters per day, with a current discharge volume of 43.95 cubic meters per day. As a secondary treatment plant, it provides biological treatment to reduce organic matter and suspended solids before discharge. The plant operates under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. For small plants serving fewer than 2,000 population equivalents, the directive allows appropriate treatment to ensure receiving waters meet quality standards. The facility's discharge volume and capacity indicate it is operating well below its design capacity, suggesting it serves a stable or declining population. The treated effluent from IDL_VIA_SOLDAINI ultimately drains into the Arno River basin, which flows through Tuscany to the Tyrrhenian Sea near Pisa. The Arno River is a major watercourse in the region, supporting diverse aquatic life and providing water for agriculture and industry. The plant's secondary treatment helps protect the river's water quality and downstream ecosystems.

The plant discharges into the Arno River basin, which flows through the Pisa province and empties into the Tyrrhenian Sea. The Arno River supports a variety of aquatic species and is an important water resource for the region. Downstream, the river passes through the city of Pisa and its coastal area, where the effluent contributes to the overall nutrient load. The secondary treatment level helps reduce organic pollution, but the plant's small size means its impact on the river's water quality is localized.
