Overview
UWWTP Rijnsaterwoude is an advanced treatment plant in Zuid-Holland, Netherlands, serving 833 people. It discharges 239.69 m³/day of treated wastewater into the local water system.
UWWTP Rijnsaterwoude is a wastewater treatment plant located in the village of Rijnsaterwoude, within the municipality of Kaag en Braassem in the province of Zuid-Holland, Netherlands. The plant serves a small population of 833 residents and operates with advanced treatment technology, ensuring high-quality effluent. The plant has a designed capacity of 1,620 m³/day and currently discharges 239.69 m³/day of treated wastewater. As a Dutch facility, it operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for sensitive areas. The Netherlands implements this directive through national regulations, ensuring compliance with stringent nutrient removal standards. The treated effluent is discharged into the local surface waters, which are part of the Rhine-Meuse-Scheldt delta system. This region is characterized by polders, canals, and lakes, and the discharge contributes to the water balance of the area. The plant plays a key role in protecting the water quality of the surrounding lakes and downstream environments, which support diverse aquatic life and recreational activities.
Environmental context
The plant discharges into the local water network within the Rhine-Meuse-Scheldt delta, a complex system of rivers, canals, and lakes that ultimately drains into the North Sea. The receiving waters are part of the Green Heart region, an ecologically sensitive area with peat meadows and lakes that support birdlife and aquatic ecosystems. Advanced treatment helps minimize nutrient loading, protecting these waters from eutrophication.
