SAN_LEONARDO_2 is a wastewater treatment facility located in the San Leonardo area of Guardiagrele, in the province of Chieti, Abruzzo, Italy. The plant serves a small population of around 1,000 residents, reflecting its role in a rural or suburban setting. It operates as part of the municipal wastewater infrastructure for Guardiagrele. The plant provides secondary treatment, which is the standard biological treatment stage required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 4,500 m³/day, the facility is sized to handle peak flows and future growth. The current discharge volume is approximately 198 m³/day, indicating significant spare capacity. The treated effluent is discharged into the local watershed, which ultimately drains into the Adriatic Sea via the Aterno-Pescara river system. The region is characterized by hilly terrain and a Mediterranean climate, with the plant playing a key role in protecting downstream water quality and supporting the ecological health of the Adriatic coastal zone.
Environmental context
The plant discharges into the local drainage network that feeds into the Aterno-Pescara river basin, which flows eastward to the Adriatic Sea. The downstream environment includes coastal ecosystems that support diverse marine life and are important for regional biodiversity. Secondary treatment reduces organic pollutants and suspended solids, helping to maintain water quality in the receiving waters and minimize eutrophication risks in the Adriatic.
