When the Portland Water District acquired the Portland Water Company in 1908, it maintained shops at Kennebec Street in Portland, but moved its meter shop to 16 Casco Street, also in Portland, in 1915 upon expansion of the District's offices.

In 1933 the meter shop was moved again, this time to 225 Douglass Street in Portland. This move was made in order to make room for the expansion of the accounting and business offices at Casco Street. This photograph was taken in 1931, before the move, when the meter shop occupied the second floor at the Casco Street office.
