Overview
UWWTP Leimuiden serves approximately 7,000 people in Leimuiden, Zuid-Holland, Netherlands. The plant operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
UWWTP Leimuiden is a municipal wastewater treatment plant located in Leimuiden, a town in the province of Zuid-Holland, Netherlands. The plant serves a population equivalent of approximately 7,000 people, classifying it as a small to medium agglomeration under European Union regulations. As a Dutch facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges into freshwater and estuaries from agglomerations above 2,000 population equivalent. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day or similar unit), indicating it is sized appropriately for its service area. The treated effluent from UWWTP Leimuiden is discharged into the local water system, which ultimately drains into the North Sea via the Rhine-Meuse-Scheldt delta. The plant plays a key role in protecting the water quality of the surrounding polder landscape and the downstream aquatic environment, which supports diverse fish and bird populations.
Environmental context
UWWTP Leimuiden discharges into the local polder waterways, which are part of the Rhine-Meuse-Scheldt delta system. These waters flow through the Netherlands' low-lying landscape and eventually reach the North Sea. The receiving waters are ecologically sensitive, supporting aquatic life and migratory birds in a region known for its intensive agriculture and dense population. Proper treatment is essential to prevent nutrient loading and maintain water quality in this interconnected delta ecosystem.
