Overview
S_MARTINO wastewater treatment plant serves Chieti, Italy, with a population equivalent of 69,000. The facility is located within 50 km of the Adriatic coast and operates under EU Urban Waste Water Treatment Directive standards.
S_MARTINO is a municipal wastewater treatment plant serving the city of Chieti in the Abruzzo region of Italy. The plant handles wastewater from a population equivalent of approximately 69,000, placing it in the medium-to-large agglomeration category under EU classification. Its location near the Adriatic coast influences its environmental management requirements. As a plant serving over 10,000 people, S_MARTINO is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment as a minimum. For discharges into sensitive areas, such as coastal zones, tertiary treatment may be required to reduce nutrients and protect marine ecosystems. The plant's designed capacity is reported as 1. 00 (likely in thousands of cubic meters per day), indicating a moderate scale of operations. The treated effluent from S_MARTINO ultimately reaches the Adriatic Sea, a semi-enclosed basin with limited water exchange, making it sensitive to nutrient pollution. The plant plays a key role in protecting coastal water quality and supporting the ecological health of the Adriatic, which hosts diverse marine life and supports local fisheries and tourism.
Environmental context
The plant discharges into the Adriatic Sea via local watercourses. The Adriatic is a shallow, semi-enclosed sea with slow water renewal, making it vulnerable to eutrophication from nutrient inputs. The coastal zone near Chieti supports seagrass meadows and nursery habitats for fish, requiring careful management of treated wastewater to prevent algal blooms and oxygen depletion.
Frequently asked questions
S_MARTINO is located in Chieti, in the Abruzzo region of Italy, near the Adriatic coast.
The plant serves a population equivalent of approximately 69,000 people.
Treated wastewater from S_MARTINO is discharged into local watercourses that flow into the Adriatic Sea.
As an Italian plant serving over 10,000 people, S_MARTINO operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment and, for sensitive coastal areas, tertiary treatment to reduce nutrients.
For agglomerations of this size, Italian plants typically provide secondary biological treatment. If discharging into sensitive coastal waters, additional nutrient removal (tertiary treatment) is often required to comply with EU directives.
