[ULPIANUS libro quinquagensimo tertio ad edictum. ] §8.5.10.prSi quis diuturno usu et longa quasi possessione ius aquae ducendae nactus sit, non est ei necesse docere de iure, quo aqua constituta est, ueluti ex legato uel alio modo, sed utilem habet actionem, ut ostendat per annos forte tot usum se non ui non clam non precario possedisse.
[ULPIANUS, book 53 on the Edict.] If anyone has acquired the right of drawing water by long-term use and long quasi-possession, it is not necessary for him to prove the legal basis by which the water right was established, such as by legacy or in some other way, but he has a beneficial action to show that he has possessed the use, say for so many years, not by force, not secretly, and not by permission.
§8.5.10.1Agi autem hac actione poterit non tantum cum eo, in cuius agro aqua oritur uel per cuius fundum ducitur, uerum etiam cum omnibus agi poterit, quicumque aquam non ducere impediunt, exemplo ceterarum seruitutium.
Moreover, proceedings can be taken by this action not only against him in whose field the water rises or through whose land it is conducted, but also against all who prevent the drawing of water, following the example of other servitudes.
et generaliter quicumque aquam ducere impediat, hac actione cum eo experiri potero.
And generally, whoever prevents the drawing of water, I will be able to proceed against him with this action.
