UWWTP Numansdorp is a municipal wastewater treatment plant serving the town of Numansdorp in the province of Zuid-Holland, Netherlands. The plant serves a population of approximately 14,000, placing it in the medium agglomeration category under Dutch and EU regulations.

The plant discharges treated wastewater into the local water system, which ultimately drains into the North Sea via the Haringvliet or the Nieuwe Waterweg. The region is part of the Rhine-Meuse-Scheldt delta, a ecologically important area that supports diverse aquatic life and is a key migratory corridor for birds.
Environmental context
The plant's discharge enters the local water network that flows into the Haringvliet, a large freshwater lake and estuary that connects to the North Sea. This area is part of the Rhine-Meuse delta, a dynamic and ecologically sensitive region that supports diverse fish populations and migratory waterfowl. The proximity to the coast (within 50 km) means that nutrient and pollutant loads from the plant can influence coastal water quality, making effective treatment important for protecting marine ecosystems.
