UWWTP Oud Beijerland - Municipal Wastewater Treatment in Zuid-Holland, Netherlands

UWWTP Oud Beijerland is a municipal wastewater treatment facility located in Oud-Beijerland, a town in the province of Zuid-Holland, Netherlands. Serving a population of 49,167, the plant is part of the national wastewater infrastructure managed under Dutch water authorities. The facility is situated in the Hoeksche Waard region, an area characterized by polders and waterways typical of the Rhine-Meuse-Scheldt delta. As a plant serving a medium-sized agglomeration, UWWTP Oud Beijerland is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for populations exceeding 15,000. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating a scale appropriate for its service population. The treated effluent from UWWTP Oud Beijerland is discharged into local waterways that ultimately drain into the North Sea via the Rhine-Meuse delta. This region is ecologically important, supporting diverse aquatic life and serving as a migratory corridor for fish and birds. The plant plays a key role in protecting water quality in the densely populated and agriculturally active province of Zuid-Holland.

UWWTP Oud Beijerland discharges into the local water system of the Hoeksche Waard, which is part of the larger Rhine-Meuse-Scheldt delta. This delta drains into the North Sea, a vital marine ecosystem. The area supports diverse aquatic habitats and is important for migratory fish species. The plant's operations help maintain water quality in a region with intensive agriculture and urban development, reducing nutrient loads that could otherwise contribute to eutrophication in downstream waters.
