DEP_COM_VALLE_SETTE_DUE is a wastewater treatment plant located in Colleferro, in the Lazio region of Italy. The plant serves a population of approximately 22,500 people, classifying it as a medium-sized agglomeration under Italian regulations. It is situated in the Valle Settedue area, near the Sacco River valley. As an Italian wastewater treatment plant, DEP_COM_VALLE_SETTE_DUE operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. And it likely employs conventional treatment processes to meet regulatory standards for discharge into local water bodies. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Tyrrhenian Sea via the Sacco River and the Liri-Garigliano river system. This region supports diverse aquatic life and is important for both ecological balance and agricultural water use in the Lazio countryside.
Environmental context
The plant's treated effluent likely enters the Sacco River, a tributary of the Liri River, which flows into the Garigliano River and then into the Tyrrhenian Sea. This watershed supports a variety of aquatic species and is used for irrigation in the surrounding agricultural areas. The proximity to the coast (within 50 km) means that nutrient loading from wastewater must be carefully managed to prevent eutrophication in coastal waters.
