Regulations for Passenger Ship Administration Article 91
If a passenger ship is equipped with the fresh water generator machine, which is approved by the shipping administration authority or ship register institute and is inspected before departure, two-thirds of the capacity of the generator may be excluded from computing the required volume of the fresh water in stock. Nevertheless, the ship shall provide emergency water even though its fresh water generator has a greater capacity than required for all persons on board.
