[POMPONIUS libro trigensimo tertio ad Sabinum. ] §8.4.11.prRefectionis gratia accedendi ad ea loca, quae non seruiant, facultas tributa est his, quibus seruitus debetur, qua tamen accedere eis sit necesse, nisi in cessione seruitutis nominatim praefinitum sit, qua accederetur: et ideo nec secundum riuum nec supra eum (si forte sub terra aqua ducatur) locum religiosum dominus soli facere potest, ne seruitus intereat: et id uerum est.
[POMPONIUS, on Sabinus, book 33] For the purpose of repair, the capacity to access those places which are not subject to the servitude is granted to those to whom the servitude is owed, provided however that it is necessary for them to access through there, unless in the grant of the servitude it was specifically predetermined by which way access should be made. And therefore, the owner of the land cannot make a place religious, either along the watercourse or above it (if by chance the water is drawn underground), lest the servitude be lost; and this is true.
sed et depressurum uel adleuaturum riuum, per quem aquam iure duci potestatem habes, nisi si ne id faceres cautum sit.
But also, it is permitted that you will deepen or raise the watercourse through which you have the right to draw water, unless it has been provided that you should not do so.
§8.4.11.1Si prope tuum fundum ius est mihi aquam riuo ducere, tacita haec iura sequuntur, ut reficere mihi riuum liceat, ut adire, qua proxime possim, ad reficiendum eum ego fabrique mei, item ut spatium relinquat mihi dominus fundi, qua dextra et sinistra ad riuum adeam et quo terram limum lapidem harenam calcem iacere possim.
If I have the right to draw water by a watercourse near your estate, these tacit rights follow: that I am permitted to repair the watercourse, that I and my workmen may access it by the nearest possible way to repair it, and likewise that the owner of the estate leave me space by which I may approach the watercourse on the right and on the left, and where I can throw earth, mud, stone, sand, and lime.
