IMPIANTO C DA ROCCHE Wastewater Treatment Plant, Pietraperzia, Sicily

IMPIANTO C DA ROCCHE is a former wastewater treatment plant located in Pietraperzia, a town in the province of Enna, Sicily, Italy. The plant served a population of approximately 5,000 people and was designed with a capacity of 8,000 cubic meters per day. It is now closed and no longer operational. The plant provided primary treatment, which involves physical processes such as sedimentation to remove solids. As a facility in Italy, it would have been subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's discharge volume was 989.82 cubic meters per day. The plant is located inland in Sicily, more than 10 km from the coast. The treated effluent likely drained into local waterways that eventually flow to the Mediterranean Sea, contributing to the island's water resources.

The plant is situated in the interior of Sicily, within the drainage basin of the Salso River or similar watercourses that flow toward the Mediterranean Sea. The region's semi-arid climate makes water quality management critical for local agriculture and ecosystems. Although the plant is closed, its historical discharges would have affected downstream water bodies, emphasizing the need for proper treatment to protect aquatic life and water resources.
