Overview
DORMELLETTO wastewater treatment plant serves Arona, Italy, in the Piemonte region. It handles a population equivalent of 50,000 and operates under EU Urban Waste Water Treatment Directive standards.
The DORMELLETTO wastewater treatment plant is located in Arona, in the Piemonte region of northern Italy. Serving a population equivalent of 50,000, the facility is part of the municipal wastewater infrastructure for the area, which includes the locality of Mercurago. The plant's location near Lake Maggiore places it in a sensitive environmental context. As a plant serving a medium-sized agglomeration, it is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum. For discharges into sensitive areas, such as lakes, tertiary treatment may be mandated to reduce nutrient loads and protect water quality. The plant's design and operation align with these regulatory requirements to ensure compliance with Italian and European standards. The treated effluent from the plant is discharged into the local water system, which ultimately drains into Lake Maggiore, a large subalpine lake that flows into the Ticino River and then into the Po River, reaching the Adriatic Sea. Lake Maggiore supports diverse aquatic life and is an important ecological and recreational resource. The plant plays a crucial role in protecting this downstream environment from pollution.
Environmental context
The DORMELLETTO plant discharges into the Lake Maggiore watershed, a large subalpine lake that flows into the Ticino River, a tributary of the Po River, which empties into the Adriatic Sea. Lake Maggiore supports diverse aquatic life, including fish species and migratory birds, and is ecologically sensitive to nutrient pollution. The plant's treatment processes help maintain water quality in this important freshwater ecosystem.
Frequently asked questions
