A more thorough explanation:

Jus Aquaeductus

Jus aquaeductus (pronounced juhz ak-wuh-duhk-tuhs) is a legal term from Roman and civil law. It refers to a servitude that allows a landowner to use pipes or channels to transport water from someone else's land.

For example, if a farmer needs water to irrigate their crops, they might have a jus aquaeductus that lets them take water from a nearby stream or river that flows through their neighbor's property. Or, a homeowner might have a jus aquaeductus that allows them to connect their house to a municipal water supply that runs under their neighbor's land.

These examples illustrate how a jus aquaeductus can be used to access water resources that are located on someone else's property. It's a way for landowners to share resources and make the most of the land they have.
