    Water Supply There has been no change in the source of the Corporation's supply. During the year all treated water was satisfactory in quality and quantity. The water is not plumbo-solvent. Chlorination is the only action required and taken in respect of any form of contamination. The average daily consumption in the city was 4,041,000 gallons, which represents an increase of 250,000 gallons per day over last year and a con¬ sumption of 60.49 gallons per head per day. The number of dwellings in the city with direct water supplied by tap in the house was 23,172 and the number supplied by standpipe 5.
