"The water distribution system of Montreal by the Department of Public Works is illustrated in this film. Valued at 60 million dollars in 1948, the system is responsible for delivering 160 million gallons of water daily to Montrealers from the immense resevoir provided by the Great Lakes. The film shows how a 5 1/2 mile long canal is filled from the resevoir via the St. Lawrence River, eventually travelling to a filtration plant. At the plant the water is filtered, chlorinated and tested periodically at various stages by a team of chemists. (A graph detailing the reduction in the typhoid death rate since water treatment began in 1909 is shown). The actual distribution begins at a low-level pumping station progressing to higher level stations throughout the city. The film concludes with various scenes of water use in Montreal. Animation sequences include: a graphic of the Great Lakes; a diagram of the filtration process; the typhoid death rate graph and a summary of the whole system in diagram."
