Jus Aquaeductus is a servitude which gives, to an owner of land, the right to bring down water through or from the land of another. This is basically a right possessed by one person to use another's property to bring down water to the former's property. Water can be brought down either from its source or from any other place.
The privilege enjoyed by virtue of this right is limited in its time of exercise. The servitude ceases to exist when the source fails and it revives when water returns. The owner of the property through which the water flows cannot divert or prevent the flow of water if water rises in, or naturally flows through the land. On the other hand, if water is brought by artificial means, it would be strictly his property. The owner in that context has the power to grant or deny the right.
