Overview
CHANIA wastewater treatment plant serves the municipality of Chania in Crete, Greece, with a population equivalent of 123,000. The facility is located near the coast and operates under EU regulatory standards.
The CHANIA wastewater treatment plant is a key municipal facility serving the city of Chania and the surrounding area in the region of Crete, Greece. With a population served of 123,000, it is classified as a large agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated in the suburb of Koumbelis, within the Chania regional unit, and its coastal location places it within 50 km of the Mediterranean Sea. As a plant serving over 100,000 people, it is subject to the EU UWWTD requirements, which mandate secondary treatment as a minimum, and tertiary treatment if the receiving waters are designated as sensitive areas. The designed capacity is reported as 1. The plant's operational status and permit information are not disclosed, but it is expected to comply with Greek national regulations implementing the EU directive. The treated effluent is discharged into the local watershed, which ultimately drains into the Sea of Crete, part of the broader Mediterranean Sea. The coastal environment supports diverse marine life and is important for tourism and fisheries. Proper treatment is essential to protect water quality and ecological health in this sensitive coastal region.
Environmental context
The CHANIA plant discharges into the local drainage network that flows into the Sea of Crete, a part of the Mediterranean Sea. This coastal area supports diverse marine ecosystems, including seagrass meadows and fish spawning grounds, and is vital for local tourism and fishing industries. The proximity to the coast necessitates advanced treatment to prevent nutrient enrichment and protect bathing water quality.
