Koekelare Wastewater Treatment Plant, West-Vlaanderen, Belgium

The Koekelare wastewater treatment plant is located in the municipality of Koekelare, within the province of West-Vlaanderen, Belgium. It serves a population of approximately 2,900 residents, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant operates with advanced treatment, which goes beyond the secondary treatment standard typically required for smaller communities, indicating a commitment to high effluent quality. With a designed capacity of 5,400 m³/day and an average daily discharge of 518.37 m³/day, the plant operates well below its capacity, suggesting room for future growth or seasonal variations. As a coastal facility within 10 km of the North Sea, the advanced treatment level is particularly important for protecting sensitive marine environments. The advanced classification implies nutrient removal or other tertiary processes. The treated effluent is discharged into local watercourses that eventually drain into the North Sea. The plant plays a key role in safeguarding the coastal waters of the Belgian coast, which support diverse aquatic life and are important for tourism and fisheries. Its advanced treatment helps minimize nutrient loading and other pollutants, contributing to the ecological health of the downstream environment.

The Koekelare plant discharges treated wastewater into local streams that flow toward the North Sea, a sensitive marine ecosystem. The Belgian coastal zone supports diverse habitats, including sandbanks and estuaries, which are important for fish, birds, and marine mammals. Advanced treatment at this plant helps reduce nutrient and pollutant loads, protecting water quality in the coastal area and supporting the ecological balance of the North Sea.
