Ten historic water towers: Chicago, Grand Avenue, Bissell Street, Compton Hill, Mannheim, Wisniowa Street in Wroclaw, Jelgava, Vukovar, Jumbo in Colchester and old Landskrona. This is a selection, not a ranking by height or age. Chicago and St. Louis towers enclosed pressure-regulating standpipes rather than conventional tanks. Vukovar is shown in an undated archival photograph. Photographs do not establish current water-supply operation or unrestricted visitor access.
