Overview
UWWTP MAARSSEN serves 12,300 people in Maarssen, Utrecht, Netherlands. The plant operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
UWWTP MAARSSEN is a municipal wastewater treatment facility located in Maarssen, a town in the province of Utrecht, Netherlands. The plant serves a population of approximately 12,300 residents, classifying it as a small to medium agglomeration under European Union classification. Its address is Zogweteringlaan, Maarssen, Stichtse Vecht, Utrecht. As a Dutch wastewater treatment plant, UWWTP MAARSSEN operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations with a population equivalent (PE) between 2,000 and 10,000, and more stringent treatment for larger agglomerations in sensitive areas. The Netherlands designates many water bodies as sensitive, often necessitating tertiary treatment for nutrient removal. The plant discharges treated effluent into the local water system, which ultimately drains into the North Sea via the Rhine-Meuse-Scheldt delta. The Utrecht region is characterized by a dense network of canals, rivers, and polders, where water quality management is critical for both ecological health and flood control. The plant's operations contribute to protecting downstream aquatic habitats and meeting the Water Framework Directive objectives for the Rhine basin.
Environmental context
The treated effluent from UWWTP MAARSSEN enters the local surface waters in the Utrecht region, which are part of the Rhine-Meuse-Scheldt delta system. This water eventually flows into the North Sea, a vital marine ecosystem supporting diverse fish populations and migratory birds. The plant's discharge must comply with Dutch water quality standards to prevent eutrophication and protect sensitive aquatic habitats in the downstream canals and rivers.
Frequently asked questions
UWWTP MAARSSEN is located at Zogweteringlaan in Maarssen, a town in the municipality of Stichtse Vecht, province of Utrecht, Netherlands.
The plant serves approximately 12,300 residents, classifying it as a small to medium agglomeration under EU classification.
The plant discharges treated effluent into local surface waters in the Utrecht region, which are part of the Rhine-Meuse-Scheldt delta system, ultimately flowing into the North Sea.
As a Dutch plant, UWWTP MAARSSEN operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of its size. The Netherlands also implements the Water Framework Directive, with many water bodies designated as sensitive areas requiring nutrient removal.
In the Netherlands, plants serving populations of this scale typically provide secondary biological treatment, often with additional nutrient removal (tertiary treatment) to meet stringent water quality standards for sensitive receiving waters.
