Drinking water in freshwater tank of ship is, in general, high in pH. This may be due to alkaline substances derived from the coating material-wash cement. To find the coating material suitable for preservation of drinking water, the authors examined the alteration of the quality of water stored in the experimental tanks coated with some synthetic resin paints. The experiments showed the following facts : The phenol resin varnish paint and the polyester paint could hold the quality of water good for drink. But they have the following demerits-expensive and dangerous exhaling poisoneous and inflamable gas during coating work. The water stored in the tank coated with wash cement was good for drink with respect to all the items except pH value. These suggest that it is necessary to develop inexpensive coating material with satisfactory quality or to find some effective methods of preventing the dissolution of alkaline substance from the cement coating.
