Overview
KRESTENA wastewater treatment plant serves the community of Skillountos in western Greece. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
KRESTENA is a wastewater treatment plant located in the municipal unit of Skillountos, within the municipality of Andritsaina-Krestena, in the regional unit of Elis, Western Greece. The plant serves a population of approximately 5,500 people, classifying it as a small agglomeration under EU regulations. As a Greek facility, KRESTENA operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for all discharges from agglomerations with a population equivalent above 2,000. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Ionian Sea. The region's rivers and coastal waters support diverse aquatic life and are important for local fisheries and tourism. Proper treatment helps protect these ecosystems from nutrient pollution and other contaminants.
Environmental context
The plant's treated effluent enters the local drainage network, which flows into the Ionian Sea via nearby rivers such as the Alfeios. The Ionian Sea is a semi-enclosed basin with sensitive marine ecosystems, including seagrass meadows and important fish nursery areas. Nutrient loading from wastewater can contribute to eutrophication, so effective treatment is critical for maintaining water quality and biodiversity in this coastal region.
