This is a photograph of the Portland Water District office, though it is unclear at which location. The District office was located at 33 Plum Street in Portland until 1915 when the office was moved to 16 Casco Street, also in Portland.

One of the photographs on the wall is of the February 1915 employee banquet held by Superintendent Eben Dyer at the Falmouth Hotel. Since the exterior walls of the Casco Street building were brick, not wood, it is supposed that this photograph was probably taken at 33 Plum Street before the location of the office was moved in June of 1915.
