UWWTP Borculo - Closed Advanced Wastewater Treatment Plant in Borculo, Gelderland

UWWTP Borculo was a wastewater treatment facility located in Borculo, a town in the municipality of Berkelland, Gelderland province, Netherlands. The plant operated with advanced treatment technology and had a designed capacity of 13,500 cubic meters per day, serving the local population and industrial discharges in the region. As an advanced treatment plant, UWWTP Borculo provided tertiary-level purification beyond secondary biological treatment, typically including nutrient removal (nitrogen and phosphorus) to meet stringent Dutch water quality standards. The plant operated under the Dutch Water Act and the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for sensitive areas and large agglomerations. The treated effluent from the plant was discharged into local surface waters within the Rhine basin, ultimately draining into the North Sea. The plant's operations helped protect the water quality of the Berkel River and downstream ecosystems, including the IJssel River and the Rhine Delta, which are ecologically sensitive areas supporting diverse aquatic life and migratory fish species.

The plant discharged into the Berkel River, a tributary of the IJssel River, which flows into the IJsselmeer and eventually the North Sea. The Rhine-Meuse-Scheldt delta is a critical ecological region for migratory birds and fish, and advanced treatment at this plant helped reduce nutrient loads that could cause eutrophication in downstream lakes and coastal waters.
