The De Valls Bluff Waterworks is a historic public water supply facility at Rumbaugh and Hazel Streets in De Valls Bluff, Arkansas. It contains a 1930s-era elevated steel water tower, built in 1936 by the Pittsburgh-Des Moines Steel Company in conjunction with the Public Works Administration as part of a project to improve the local water supply. It was added to the National Register of Historic Places in 2007, as part of a multiple-property listing that included numerous other New Deal-era projects throughout Arkansas. The property also contains several non-contributing buildings, including a shed, aeration chamber, and water tank.[2]
