Attention should be paid upon the fact that over 90 percent of Japanese vessels were blamed for the contamination of drinking water by bacillus and alkali derived from cement. The contamination occurs during the procedures of taking, stowing and supplying, due to inadequate location of hydrant on the pier, conveyance by wooden built water barges, filling by unclean hose and pipe, and careless use of water just after cement-coating without sufficient washing. As for the method of purifying water, the use of filter layer and chlorination are rather popular, and disinfection by ultraviolet ray is tried in some vessels. Tests were made on the application of special paint for fresh water tank instead of cement. The improvement for supplying clean water should be made by the collaboration of shipbuilders, sanitary engineers and shipping firms.
