[PAULUS libro secundo epitomarum Alfeni digestorum. ] §8.3.29.prQui duo praedia confinia habuerat, superiorem fundum uendiderat: in lege ita dixerat, ut aquam sulco aperto emptori educere in fundum inferiorem recte liceat: si emptor ex alio fundo aquam acciperet et eam in inferiorem ducere uellet, quaesitum est, an possit id suo iure facere nec ne.
[PAULUS, Epitome of Alfenus' Digests, Book 2] A person who had owned two adjoining estates had sold the upper estate; in the contract of sale he had provided that the buyer should be rightfully permitted to drain water by an open ditch into the lower estate. If the buyer should receive water from another estate and wish to conduct it into the lower estate, the question arose whether he could do this of his own right or not.
respondi nihil amplius, quam quod ipsius fundi siccandi causa deriuaret, uicinum inferiorem recipere debere.
I replied that the lower neighbor is under no obligation to receive anything more than what the buyer drains for the purpose of drying that estate itself.
