Delmont Pumphouse

The Delmont Pumphouse is a historic waterworks facility and fire station on West Main Street in Delmont, South Dakota. It is a single-story brick structure, built in 1903 by the city to house a compression tank for its water supply. In 1907 it was enlarged to also house the city's fire truck. It was used as a firehouse until 1968, and was used for storage thereafter. It has been restored and is now a museum operated by the Historical Society of Delmont.

The building was listed on the National Register of Historic Places in 1998.
