[ULPIANUS libro uicensimo nono ad Sabinum. ] §18.1.47.prSi aquae ductus debeatur praedio, et ius aquae transit ad emptorem, etiamsi nihil dictum sit, sicut et ipsae fistulae, per quas aqua ducitur,
[ULPIAN, On Sabinus, Book XXIX] If a right of conducting water is owed to an estate, the right to the water also passes to the buyer, even if nothing has been said, just as the pipes themselves, through which the water is conducted, [also pass].
