Overview
PANAGHIA POTAMIA THASSOU wastewater treatment plant serves the coastal community of Chrysi Ammoudia on Thassos Island, Greece. It treats wastewater for approximately 16,000 people, discharging into the Aegean Sea.
PANAGHIA POTAMIA THASSOU is a wastewater treatment plant located in Chrysi Ammoudia, a coastal settlement on the island of Thassos in the Eastern Macedonia and Thrace region of Greece. The plant serves a population of around 16,000, reflecting the seasonal tourism-driven demand typical of Greek island communities. As a Greek facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the discharge enters sensitive areas, such as coastal waters used for bathing or aquaculture. The treated effluent is discharged into the Aegean Sea, a semi-enclosed sea with high ecological sensitivity. The surrounding waters support diverse marine life, including seagrass meadows and fish spawning grounds. Proper treatment is critical to prevent eutrophication and protect the coastal ecosystem, which is also vital for local tourism and fisheries.
Environmental context
The plant discharges into the Aegean Sea, which receives water from the broader Mediterranean basin. The coastal waters around Thassos are ecologically sensitive, supporting seagrass meadows and marine biodiversity. Effective wastewater treatment helps prevent nutrient pollution that could harm these habitats and the local tourism-dependent economy.
Frequently asked questions
The plant is located in Chrysi Ammoudia, a coastal village on the island of Thassos in the Eastern Macedonia and Thrace region of Greece.
The plant serves approximately 16,000 people, a population that likely increases during the tourist season due to the area's popularity as a beach destination.

As a Greek plant serving over 10,000 people, it falls under the EU UWWTD (91/271/EEC), which mandates secondary treatment as a minimum. If the receiving waters are designated as sensitive, tertiary treatment may be required.
For agglomerations of this size, Greek plants typically provide secondary biological treatment. In coastal areas like Thassos, additional nutrient removal may be implemented to protect bathing waters and marine ecosystems.
