Regulation 26 Supply of drinking water

Cold drinking water shall be laid on to the galley taps which shall be readily accessible to the crew.

The drinking water shall be supplied from tanks of a capacity of at least 4·5 litres for each member of the crew for each day likely to elapse between successive replenishments of water. If the water supplied to the washing accommodation is of the standard required for drinking water, the storage tanks may be combined. If they are combined, the total tank capacity shall be not less than 49·5 litres per person for each day likely to elapse between successive replenishments of water.

If gravity service tanks are fitted, they shall be directly connected with the vessel's main drinking water storage tanks.

If distilling or evaporating plant is provided for the supply of drinking water, the storage capacity may be reduced from that specified in paragraph (2) above, but the tanks shall still be sufficient to provide at least two days' supply.

Where drinking water is produced by a low pressure generator working at a temperature below 100°C, the water so produced shall be treated by an automatic chlorination unit.

Where drinking water is used for flushing water closets, supplying engine auxiliaries or for any purpose other than drinking, precautions shall be taken to ensure that the drinking water supply cannot be contaminated as a result of that use.
