Overview
UWWTP Veenendaal serves approximately 70,700 people in Overberg, Utrecht, Netherlands. The plant operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
UWWTP Veenendaal is a municipal wastewater treatment facility located in Overberg, Utrecht, Netherlands. It serves an estimated population of 70,700, classifying it as a medium-to-large agglomeration under EU regulations. The plant is situated in the Utrechtse Heuvelrug region, an area characterized by sandy soils and nature reserves. As a plant serving over 10,000 population equivalents, it is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary biological treatment as a minimum. For agglomerations between 10,000 and 150,000 PE, the directive also mandates more stringent treatment if the receiving waters are sensitive to eutrophication. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day or similar unit), indicating a facility sized for its service population. The treated effluent from UWWTP Veenendaal is discharged into local watercourses that eventually drain into the Rhine-Meuse-Scheldt delta, a major European river system flowing into the North Sea. The downstream environment includes the Nederrijn and Lek rivers, which support diverse aquatic life and are important for water supply and recreation. The plant's operation helps protect the water quality of these sensitive lowland rivers and the North Sea coastal ecosystem.
Environmental context
UWWTP Veenendaal discharges into the Rhine-Meuse-Scheldt delta, which flows through the Netherlands into the North Sea. The receiving waters include the Nederrijn and Lek rivers, part of the Rhine basin. This region supports diverse aquatic habitats and is ecologically sensitive due to nutrient loading and industrial activity. The plant's treatment helps mitigate eutrophication risks in downstream lakes and coastal zones.
Frequently asked questions
UWWTP Veenendaal is located at Slaperdijk 2a, Overberg, in the province of Utrecht, Netherlands. It serves the nearby city of Veenendaal and surrounding areas.
The plant serves approximately 70,700 people, classifying it as a medium-to-large agglomeration under the EU Urban Waste Water Treatment Directive.
The treated effluent is discharged into local watercourses that drain into the Rhine-Meuse-Scheldt delta, eventually reaching the North Sea. The specific receiving water body is part of the Rhine basin.
As a Dutch plant serving over 10,000 population equivalents, UWWTP Veenendaal operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment and, if needed, tertiary treatment in sensitive areas.
For agglomerations of this size in the Netherlands, secondary biological treatment is standard, often with nutrient removal to protect sensitive receiving waters like the Rhine delta. Many plants also incorporate phosphorus and nitrogen removal to meet EU water quality standards.
