Brunnenhaus (mineral water)
From the 19th century onwards, the term fountain house referred to a well operation in which mineral water was filled into clay jugs, corked, sealed, stored and prepared for dispatch. A well house was usually in the immediate vicinity of a well or a spring. In some cases, a well house, such as the large well house at Heppinger Brunnen from 1832, was built directly above a spring and was the center of the production and shipping of mineral water in mineral water jugs made of baked clay.
