Sint Niklaas Wastewater Treatment Plant - Sint-Niklaas, Belgium

The Sint Niklaas wastewater treatment plant is located in Sint-Niklaas, Oost-Vlaanderen, Belgium. It serves a population equivalent of 50,200, classifying it as a medium-sized agglomeration under EU regulations. The plant is situated in the Flemish region, an area with dense urbanization and industrial activity. Under the EU Urban Waste Water Treatment Directive 91/271/EEC, agglomerations of this scale are required to provide secondary treatment as a minimum. In sensitive areas, such as those draining into nutrient-sensitive water bodies, tertiary treatment may be mandated. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating a facility sized for its service population. The plant discharges treated effluent into local waterways that ultimately drain into the Scheldt River basin. The Scheldt flows through Belgium and the Netherlands before reaching the North Sea. This river system supports diverse aquatic life and is an important ecological corridor in the region.

The plant's treated effluent enters the local water network, which feeds into the Scheldt River basin. The Scheldt flows through Flanders and into the Netherlands, discharging into the North Sea. This watershed supports a variety of fish and bird species and is subject to nutrient management regulations under the EU Nitrates Directive and Water Framework Directive to prevent eutrophication in downstream coastal waters.
