CHIEUTI Wastewater Treatment Plant, Chieuti, Puglia, Italy

The CHIEUTI wastewater treatment plant is located in Chieuti, a town in the province of Foggia, Puglia, Italy. It serves a population of approximately 1,254 people, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated near the Adriatic coast, within 10 km of the shoreline. The plant provides secondary treatment, which is the minimum required by the EU UWWTD for freshwater discharges from agglomerations of this size. The designed capacity is 2,500 m³/day, and the current discharge volume is 255 m³/day, indicating ample capacity for current loads. As a small plant in a coastal area, it plays a role in protecting the marine environment from untreated wastewater. The treated effluent likely discharges into a local watercourse or directly into the Adriatic Sea, contributing to the health of the coastal ecosystem. The region's drainage ultimately flows into the Adriatic Sea, which supports diverse marine life and is an important area for fisheries and tourism. Proper treatment helps prevent nutrient pollution and safeguards water quality.

The plant's discharge enters the local watershed, which drains into the Adriatic Sea. The Adriatic Sea is a semi-enclosed basin with sensitive marine ecosystems, including seagrass meadows and nursery habitats for fish. Nutrient inputs from wastewater can lead to eutrophication, so secondary treatment helps mitigate this risk. The coastal location makes the plant's performance critical for maintaining bathing water quality and supporting local biodiversity.
