another large doorway. In 1978 Pierce Construction of Lena was hired to completely or partially brick over all doors and windows on the building. A new windowed, wooden door was installed in a new opening on the east facade of the Electric Plant. The building had two more additions in 1982. A red brick addition with an by garage door was added to the north elevation and a shed addition with a by garage door was added to the southeast elevation, both built in 1982. Reservoir The on site reservoir was completed in 1907 and is connected to the old Electric Plant Building through two cast iron pipes. The 100,000 gallon (378,541 L) reservoir is constructed from concrete and features a roof of wood and metal. Significance The Lena Water Tower has been in continuous service since it was built in 1896 and is the tallest structure in the village. Its role in providing the citizens of Lena with water services beginning in 1896 is the primary reason the structure was listed on the U.S. National Register of Historic Places on February 20, 1997. Included in the listing to the National Register was the reservoir, which was added as a contributing property. The Electric Plant Building, however, was not included in the listing because of the large number of modern alterations it has undergone. The Lena Water Tower is believed to be one of three in the state of Illinois designed and built of similar construction and has become a symbol of the village of Lena.
