Overview
TRIESTE_BARCOLA is a primary treatment plant serving 2,800 people in Trieste, Friuli-Venezia Giulia, Italy. It discharges 554.30 m³/day of treated wastewater near the Adriatic coast.
TRIESTE_BARCOLA is a wastewater treatment plant located in the Barcola district of Trieste, in the Friuli-Venezia Giulia region of northeastern Italy. The plant serves a population of approximately 2,800 residents and is situated along the Adriatic coastline, reflecting the urban and coastal character of the area. The facility provides primary treatment, which involves physical processes such as sedimentation to remove suspended solids. With a designed capacity of 7,500 m³/day and a current discharge volume of 554.30 m³/day, the plant operates well below its capacity. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), small agglomerations like this one are required to provide appropriate treatment before discharge into coastal waters. The treated effluent is discharged into the Gulf of Trieste, part of the northern Adriatic Sea. This coastal area supports diverse marine life and is influenced by the karst topography of the region. The discharge contributes to the nutrient load in the gulf, which is a semi-enclosed basin with limited water exchange, making it sensitive to eutrophication.
Environmental context
The plant discharges into the Gulf of Trieste, a northern embayment of the Adriatic Sea. This coastal zone is part of a karst landscape and supports seagrass meadows and fish nurseries. The Adriatic Sea is a semi-enclosed basin with slow water circulation, making it vulnerable to nutrient enrichment from wastewater discharges. The local watershed includes the Timavo River and other small coastal streams that drain into the gulf.
Frequently asked questions
TRIESTE_BARCOLA is located in the Barcola district of Trieste, in the Friuli-Venezia Giulia region of northeastern Italy, near the Adriatic coast.
The plant serves approximately 2,800 residents in the Barcola area of Trieste.
The plant discharges treated effluent into the Gulf of Trieste, which is part of the northern Adriatic Sea.
TRIESTE_BARCOLA provides primary treatment, which involves physical removal of solids through sedimentation. Under the EU Urban Waste Water Treatment Directive, small coastal agglomerations may be subject to less stringent requirements, but primary treatment is the minimum for such discharges.
As a small agglomeration (under 10,000 population equivalent) discharging into coastal waters, TRIESTE_BARCOLA is subject to Article 6 of the EU UWWTD, which requires appropriate treatment. Primary treatment meets the directive's requirements for such discharges, provided it does not adversely affect the environment.
