IDL_ROCCASTRADA_CAPOLUOGO Wastewater Treatment Plant, Roccastrada, Tuscany

IDL_ROCCASTRADA_CAPOLUOGO is a municipal wastewater treatment plant located in Roccastrada, a town in the province of Grosseto, Tuscany, Italy. The plant serves a population of approximately 3,193 people and has a designed capacity of 3,100 cubic meters per day, with an actual discharge volume of 632.10 cubic meters per day. The plant provides secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Secondary treatment typically involves biological processes to remove organic matter and suspended solids, ensuring compliance with European effluent quality standards. Treated wastewater from the plant is discharged into the local watershed, which ultimately drains into the Tyrrhenian Sea. The plant plays a key role in protecting the region's water resources, including the nearby Ombrone River basin, by reducing pollutant loads before discharge.

The plant discharges into the drainage basin of the Ombrone River, which flows through southern Tuscany and empties into the Tyrrhenian Sea near Grosseto. The Ombrone River supports diverse aquatic life and is an important ecological corridor in the region. The Tyrrhenian Sea, part of the Mediterranean, is a semi-enclosed sea with sensitive marine ecosystems, including seagrass meadows and coastal habitats that benefit from reduced nutrient and pollutant inputs from well-treated wastewater.
