In May of 1969, during the year of its
Centennial Anniversary, the Chicago Water Tower was
selected by the American Water Works Association to
be the first American Water Landmark in the nation.
The tower was completed in 1869 and survived the
Great Chicago Fire of 1871. The architect was
William W. Boyington and the tower is constructed
of Joliet limestone blocks quarried in Illinois.
The octagon shaped tower houses a 138-foot-tall
standpipe, three feet in diameter and rises154 feet
above the ground level. This standpipe served to
equalize pressure and to minimize the pulsations of
the water flowing in the mains.
