UWWTP DE BILT - Wastewater Treatment Plant in Groenekan, Utrecht, Netherlands

UWWTP DE BILT is a municipal wastewater treatment plant located in Groenekan, in the province of Utrecht, Netherlands. It serves a population of approximately 55,150 people, classifying it as a medium-sized agglomeration under EU regulations. The plant is situated in a densely populated region with significant water management infrastructure. As a Dutch plant, UWWTP DE BILT operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The Netherlands has extensive wastewater treatment standards, often exceeding EU minimums, with many plants employing advanced nutrient removal to protect sensitive water bodies. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating adequate capacity for its service area. The treated effluent from UWWTP DE BILT is discharged into the local water system, which ultimately drains into the North Sea via the Rhine-Meuse-Scheldt delta. This region is ecologically sensitive, supporting diverse aquatic life and serving as a critical migratory corridor for fish and birds. The plant plays a key role in maintaining water quality in the Utrechtse Heuvelrug area and downstream ecosystems.

The plant discharges into the local water network that flows into the Rhine River basin, which drains into the North Sea via the Dutch delta. This watershed supports diverse aquatic habitats and is important for migratory fish species. The region's low-lying terrain and high population density make effective wastewater treatment critical to prevent eutrophication and protect downstream coastal ecosystems.
