FOSSO GAUTERIO Wastewater Treatment Plant, Lettomanoppello, Abruzzo

FOSSO GAUTERIO is a municipal wastewater treatment plant located in Lettomanoppello, a town in the province of Pescara, Abruzzo, Italy. The plant serves a population of approximately 1,800 residents and operates with a designed capacity of 1,200 cubic meters per day, currently discharging 520.55 cubic meters per day. As a secondary treatment facility, FOSSO GAUTERIO provides biological treatment to remove organic matter and suspended solids, meeting the standards required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The directive mandates secondary treatment for populations between 2,000 and 10,000, and while this plant serves fewer than 2,000, it still adheres to national Italian regulations that align with EU standards. The treated effluent is discharged into the local watershed, which ultimately drains into the Adriatic Sea via the Pescara River basin. The plant plays a key role in protecting the region's water quality, particularly the downstream aquatic ecosystems and the coastal environment of the Adriatic Sea, which supports diverse marine life and tourism.

The plant discharges into the Pescara River basin, which flows into the Adriatic Sea. The Adriatic Sea is a semi-enclosed basin with sensitive ecosystems, including seagrass meadows and fish spawning grounds. The plant's secondary treatment helps reduce nutrient loads that could otherwise contribute to eutrophication in the coastal zone, supporting the ecological health of the river and marine environments.
