Steenokkerzeel Noord Wastewater Treatment Plant, Kampenhout, Belgium

Steenokkerzeel Noord is an advanced wastewater treatment plant located in Kampenhout, within the province of Vlaams-Brabant, Belgium. The facility serves a population of approximately 3,700 residents, classifying it as a small agglomeration under EU regulations. It operates as part of the regional wastewater infrastructure managed by the Flemish environmental authority. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC). Its designed capacity is 3,600 m³/day, and it currently discharges 661.37 m³/day of treated effluent. This indicates that the plant operates well below its capacity, allowing for future growth or seasonal variations. The treated wastewater is discharged into local water bodies that eventually drain into the Scheldt River basin and the North Sea. The advanced treatment ensures high-quality effluent, protecting the sensitive aquatic ecosystems in the region. The plant plays a key role in maintaining water quality in the Dijle and Zenne river systems, which are part of the larger Scheldt estuary.

The plant discharges into the Dijle River catchment, which flows into the Rupel River and then the Scheldt River, ultimately reaching the North Sea. This region supports diverse aquatic life and is an important migratory corridor for fish. The advanced treatment helps reduce nutrient loading and protects downstream water quality in the Scheldt estuary, a ecologically sensitive area.
