Ruddervoorde Wastewater Treatment Plant, Waardamme, West-Vlaanderen, Belgium

Ruddervoorde is a wastewater treatment plant located in Waardamme, part of Oostkamp municipality in West-Vlaanderen, Belgium. It serves a population of 2,800 people, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated inland, more than 10 km from the coast, and its operations are part of Belgium's comprehensive water management infrastructure. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU UWWTD for agglomerations of this size. With a designed capacity of 3,600 m³/day and a current discharge volume of 500.50 m³/day, the facility operates well within its capacity. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. The treated effluent is discharged into local watercourses that eventually drain into the North Sea via the Scheldt basin. The plant plays a key role in maintaining water quality in the region, supporting aquatic ecosystems and downstream uses such as recreation and agriculture. Its advanced treatment helps reduce nutrient loads that could otherwise contribute to eutrophication in coastal waters.

The plant discharges into the local water network that feeds into the Scheldt River basin, ultimately reaching the North Sea. This coastal zone is ecologically sensitive, supporting diverse marine life and important fisheries. Advanced treatment at Ruddervoorde helps minimize nutrient pollution, protecting downstream water quality and preventing algal blooms in the North Sea.
