Impianto Locati Wastewater Treatment Plant, Locati, Sicily, Italy

Impianto Locati is a municipal wastewater treatment plant located in Locati, a small town in the province of Palermo, Sicily, Italy. The plant serves a population of 811, classifying it as a small agglomeration under Italian and EU regulations. It operates under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for all inland discharges from agglomerations of this size. The plant provides secondary treatment, which typically involves biological processes to reduce organic matter and suspended solids. With a designed capacity of 900 cubic meters per day and an actual discharge volume of 160.55 cubic meters per day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. Secondary treatment in small Italian plants often uses activated sludge or biological filters. The treated effluent is discharged into a local watercourse that eventually drains into the Mediterranean Sea. Sicily's inland waters support diverse aquatic life and are important for local agriculture. The plant's operation helps protect downstream ecosystems and coastal water quality, particularly given the region's sensitivity to nutrient pollution.

The plant discharges into a local stream that flows through the Madonie mountain range and eventually reaches the Tyrrhenian Sea, part of the Mediterranean Sea. The watershed supports diverse aquatic habitats and is important for regional biodiversity. The area is characterized by Mediterranean climate with seasonal rainfall, making consistent treatment crucial to prevent nutrient loading and protect downstream coastal ecosystems.
