A one-liter container for transporting water on Arrakis; made of high-density, shatterproof plastic with positive seal.

One day Ebrahim found an unattended literjon of water and drunk it, something that was considered a very important crime among the Zensunni tribes of Arrakis, since water was scarce and vital. The shame would be very grave if he was accused. It was decided between his father and Dhartha that it would be better if the blame would go on an orphan, Selim. Expelled from the sietch as a water stealer.

There was this drylander who was asked which was more important, a literjon of water or a vast pool of water?

Some speculate that a literjon is simply a container of volume 1L. View http://www.jacurutu.com/viewtopic.php?t=4142
