Overview
RODOS wastewater treatment plant serves the city of Rhodes, Greece, with a population equivalent of 153,158. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
The RODOS wastewater treatment plant is located in Kallithea, Rhodes, within the South Aegean region of Greece. It serves the city of Rhodes, a major urban and tourist center on the island, with a population equivalent of 153,158. The plant is situated near the coast, reflecting the island's Mediterranean setting. As a large agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC), the plant is required to provide at least secondary treatment, with tertiary treatment expected if the receiving waters are sensitive. The directive also mandates nutrient removal for discharges into areas prone to eutrophication. The plant's designed capacity is 1. The treated effluent is discharged into the surrounding marine environment of the Aegean Sea. The coastal waters near Rhodes support diverse marine life, including seagrass meadows and fish populations, making proper treatment essential to prevent nutrient enrichment and protect local ecosystems. The plant plays a key role in safeguarding the island's coastal water quality, which is vital for both tourism and biodiversity.
Environmental context
The RODOS plant discharges into the Aegean Sea, a semi-enclosed basin connected to the Mediterranean. The coastal waters around Rhodes are ecologically sensitive, supporting seagrass habitats and marine biodiversity. Effective wastewater treatment is critical to prevent eutrophication and protect the island's tourism-dependent coastal environment.
