The water management system of the city of Augsburg has evolved in successive phases from the 14th century to the present day. It includes a network of canals, water towers dating from the 15th to 17th centuries, which housed pumping machinery, a water-cooled butchers’ hall, a system of three monumental fountains and hydroelectric power stations, which continue to provide sustainable energy today. The technological innovations generated by this water management system have helped establish Augsburg as a pioneer in hydraulic engineering.
