The story
The VKU was founded in 1949 in Rüdesheim am Rhein. After the Second World War, the VKU supported municipal enterprises in their restructuring efforts. After the collapse of the GDR in 1989, the VKU aided local and regional authorities in Eastern Germany in reconstructing municipal energy and water supply infrastructure. In 2011 the formerly independent association for waste management and city cleaning (VKS – Verband kommunale Abfallwirtschaft und Stadtreinigung) became a department of VKU.
