Salem's Folly Hill Reservoir: Inspecting and Rehabilitating a Century-Old Concrete Tank

摘要

2014 marked the Centennial of Salem's Great Fire of 1914, when lack of water pressure for f iref ight-ing contributed to the destruction of 251 acres of the City's heart. The fire led to the 1915-16 construction of the 10.5-MG Folly Hill Reservoir, now one of the oldest concrete reservoirs in the state. In 2011-12, this football-field sized tank was drained and chemically cleaned to perform structural inspections and concurrent mixing system installation. A major rehabilitation program is scheduled for 2015 completion, including structural repairs and a roof liner.
