pump house: a building in which are located and operated the pumps of an irrigation system (as a spa): a pumping station https://www.merriam-webster.com/dictionary/pump house

"In the UK, during the Victorian Era, there was a fashion for public buildings to feature highly ornate architecture. Consequently, a considerable number of former pumping stations have been listed and preserved. The majority were originally steam-powered, and where the steam engines are still in situ, many of the sites have since re-opened as museum attractions." https://en.wikipedia.org/wiki/Pumping_station#United_Kingdom
