This pond is fed by the purified water of the sewage plant, which is still very rich in nutrients. This highly eutrophic body of water is partially covered with white water lilly (Nymphaea alba) and frogsweed (Luronium natans). In addition, the pond is densely populated with fish and turtles. On the southern side it is separated from the road by a reed belt. The pond surrounds the south side of the building of the waste management company which is connected to the adjacent road by a bridge.
