U-boat and fresh/drinking water issues
29 pages of various subjects - but I could not find anything about fresh water ...
It is obvious that when U-boat goes for 3-4 weeks patrol, the issue of drinking water is as much important as fuel or torpedoes. I have a number of questions concerning this issue.
1. Fresh water had to be stored in a tanks inside U-boat. How many tanks, how big and where located on the ship ?
2. When fresh water from the tank was used up, was the tank filled up with a salt water to secure proper trim of U-boat ?
3. Was it some Kriegrsmarine regulations concerning ammount of fresh water per a crew member a day ?
4. Did milk cow U-boat resupplied U-boats with fresh water ?
5. What kind of water was used in U-boat toilet, fresh or salt ?
6. Kitchen area: did they use fresh water to wash plates/pots/silverware ?
7. How about desalination units ? Did they have such a device on U-boat and if yes, from what year ? What was a production output of such a device ?
Info about literature (preferably English language) concerning fresh/drinking water would be appreciated.
I will be very gratefull for any information regarding U-boat and drinking water.

Hi,
For Type XXI: Battery water 410 gallons, Drinking water 1592 gallons, Wash water 153 gallons plus 3602 gallons in WRT tanks. Desalinization capacity remained 63.5 gallons per day.
Storage tanks varied per submarine type.

Rand

Hi,
Weight regulating tanks? By description, it appears to be the torpedo compensating tanks.
Note that the Type XXI desalinization unit had the same 63.5 gallon output as the Type IX, but the Type XXI had three times as many batteries. Drinking water tanks were filled from a tap ashore, while wash water tanks were filled from fire hydrants.
