Shouldn't the recommended needs for fluid be 30 ml per kg of body weight and not 250 ml per kg of body weight?

Wouldn't 17,000 ml of fluid be lethal to a person weighing 150 pounds which is equal to 68 kg since 68 kg x 250 ml is 17,000 ml?

For an elderly person who is healthy, all organs functioning normally, not taking diruretics or other medication that increases sensible and insensible water loss, then 30mL per kilogram per day is the minimum amount that would be adequate to maintain normal osmolality and replace regular water loss. 

A well known textbook, Modern Nutrition in Health and Disease by Shils, Olson, et al., states that anything over 15 liters a day is excessive for an elderly person, so yes, experts advise that 17 liters for a 68 kilogram elderly person is too much and possibly fatal depending on that person's kidney function.
