[PAULUS libro tertio decimo ad Plautium. ] §8.6.7.prSi sic constituta sit aqua, ut uel aestate ducatur tantum uel uno mense, quaeritur quemadmodum non utendo amittatur, quia non est continuum tempus, quo cum uti non potest, non sit usus.
[PAULUS, from the thirteenth book on Plautius.] If a water right is established in such a way that it is drawn only in summer or only for one month, it is asked how it is lost by non-use, because there is no continuous time in which, when one cannot use it, there is non-use.
itaque et si alternis annis uel mensibus quis aquam habeat, duplicato constituto tempore amittitur.
Therefore, even if someone has water in alternate years or months, it is lost by double the established time.
idem et de itinere custoditur.
The same rule is observed also concerning a right of way.
si uero alternis diebus aut die toto aut tantum nocte, statuto legibus tempore amittitur, quia una seruitus est: nam et si alternis horis uel una hora cottidie seruitutem habeat, Seruius scribit perdere eum non utendo seruitutem, quia id quod habet cottidianum sit.
If, however, it is on alternate days, or for the whole day, or only by night, it is lost by the time established by law, because it is a single servitude; for even if one has a servitude on alternate hours or for one hour daily, Servius writes that he loses the servitude by non-use, because what he has is daily.
