Cold drinking water for purposes of drinking, cooking and dish washing shall be laid on to taps in galleys, bars and pantries, and in the case of any mess room provided for members of the crew for whom no pantry is provided, to a tap in that mess room.
The tanks from which drinking water and the fresh water laid on to wash basins, baths and showers is supplied and any plant installed on board ship from which drinking water and/or fresh water is produced shall be of a capacity to ensure an adequate supply of such water at all times for all members of the crew, provided that as a minimum the tanks shall be sufficient to provide at least 2 days supply of such water.
The drinking water and fresh water storage tanks, any manholes leading into them and all pipes and other parts of the distribution systems for drinking and fresh water shall be so arranged and constructed as to allow efficient maintenance and prevent any risk of contamination.
Where drinking water and/or fresh water is produced by plant on board the water so produced shall be treated by suitable automatic means of disinfection.
In every ship of 1,000 tons or over a cooling tank or other suitable means of cooling a supply of drinking water shall be provided and the water so cooled shall be laid on so that it is readily available to the crew.
In ships of 1,000 tons or over any primary pumping necessary for the supply of drinking water and/or fresh water in the crew accommodation shall be by mechanical power; alternative pumping arrangements shall be provided to supply drinking water and/or fresh water in the event of a breakdown of the primary pumping system. When an enclosed pressurized system is employed, the pumps provided for the alternative pumping system shall be power operated and all pumps required for primary and alternative pumping shall be fitted with automatic controls.
