Overview
CHANIOTIS wastewater treatment plant serves the Pallini municipal unit in Chalkidiki, Greece. It treats wastewater from approximately 11,554 residents and is located within 50 km of the coast.
The CHANIOTIS wastewater treatment plant is situated in the Pallini municipal unit of Kassandra, Chalkidiki, in the Central Macedonia region of Greece. It serves a population of about 11,554 people, classifying it as a medium-sized agglomeration under Greek and EU regulations. The plant is part of the regional wastewater infrastructure managed by the local municipality. 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 discharging into coastal or inland waters. The plant's operational status and permit information are not disclosed in public records. The treated effluent from CHANIOTIS ultimately discharges into the Aegean Sea via local watercourses. The plant's proximity to the coast (within 50 km) means its discharge can affect coastal water quality and marine ecosystems. The region's tourism-dependent economy relies on clean coastal waters, making effective wastewater treatment essential for both environmental and economic sustainability.
Environmental context
The CHANIOTIS plant discharges into the Aegean Sea, a semi-enclosed sea with limited water exchange that is sensitive to nutrient pollution. The local watershed includes small streams that drain the Kassandra peninsula, supporting coastal habitats and marine biodiversity. The area is ecologically significant for seagrass meadows and fish spawning grounds, which can be impacted by nutrient loading from wastewater. Effective treatment helps protect these ecosystems and maintain water quality for tourism and recreation.
