A contingency water storage system container (not flown) added to post Apollo 13 flights to provide drinking water in the event that water could not be obtained from the regular Comand Module potable water tank. The collapsible 1-gallon container hosts a 6 inch plastic cube covered by Beta cloth and would have a fill hose connected to its dispenser valve.

The bag could also be used to store urine as a backup to the waste management system overboard dump nozzles.
