Impianto C da Mulini Wastewater Treatment Plant, Gangi, Sicily

Impianto C da Mulini is a wastewater treatment plant located in Gangi, a town in the province of Palermo, Sicily, Italy. The plant serves a population of approximately 8,700 residents, making it a small to medium agglomeration under EU classification. It is situated inland, away from the coast, and its operations are part of the municipal wastewater infrastructure for the area. As an Italian facility, it operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The treated effluent from the plant is discharged into local water bodies that eventually drain into the Mediterranean Sea. The plant plays a key role in protecting the local watershed and downstream ecosystems, including rivers and coastal waters, from pollution. Its operation supports the environmental health of the region, which is characterized by Mediterranean climate and diverse aquatic habitats.

The plant discharges into local streams that flow into the Imera Settentrionale river basin, eventually reaching the Tyrrhenian Sea. This watershed supports diverse aquatic life and is important for regional biodiversity. The plant's treatment helps protect downstream water quality in a region with sensitive Mediterranean ecosystems.
