[PAPIRIUS IUSTUS libro primo de constitutionibus. ] §8.3.17.prImperatores Antoninus et Uerus Augusti rescripserunt aquam de flumine publico pro modo possessionum ad irrigandos agros diuidi oportere, nisi proprio iure quis plus sibi datum ostenderit.
[PAPIRIUS IUSTUS, On Constitutions, Book 1] The Emperors Antoninus and Verus Augusti wrote in a rescript that water from a public river ought to be divided for irrigating fields in proportion to the size of the possessions, unless someone should show that more was given to him by a specific right.
item rescripserunt aquam ita demum permitti duci, si sine iniuria alterius id fiat.
They also wrote in a rescript that water is permitted to be drawn only if this is done without injury to another.
