PLANOIANNI Wastewater Treatment Plant, Penne, Italy - Secondary Treatment for Small Community

PLANOIANNI is a wastewater treatment plant located in Penne, a town in the province of Pescara, Abruzzo, Italy. The plant serves a small population of 600 people, reflecting its role in a rural or small urban setting. It is situated in the Contrada Casavalignani area near Santa Caterina. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive 91/271/EEC for agglomerations of this size. The designed capacity is 600 m³/day, and the current discharge volume is 82.19 m³/day, indicating operational capacity well within design limits. The plant is not within 10 km of the coast but is within 50 km, suggesting its discharge eventually reaches the Adriatic Sea via local waterways. The treated effluent from PLANOIANNI likely flows into the Tavo River or its tributaries, which drain into the Adriatic Sea. This coastal region supports diverse aquatic life and is important for local fisheries and tourism. The plant's operation helps protect the water quality of the receiving water bodies and the downstream marine environment.

PLANOIANNI discharges into the Tavo River basin, which flows into the Adriatic Sea near Pescara. The Adriatic Sea is a semi-enclosed basin with sensitive ecosystems, including seagrass meadows and fish spawning grounds. The plant's secondary treatment reduces organic pollutants and suspended solids, helping to maintain water quality in the river and coastal zone, which supports tourism and fishing activities.
