Aqueduct
The word for a pipe or channel that carries water from a distant source is "aqueduct." Aqueducts are designed to transport water for various purposes, including irrigation, drinking water supply, and industrial use. They can be constructed above ground or as underground conduits, depending on the landscape and engineering requirements.
For a point in space (or from a distant light object), spherical waves are emitted. From a point source on the surface of a liquid, circular waves will come out. In both cases the source will be the focus of the emitted waves.
A qanat is an underground water management system that channels water from an underground source to the surface for irrigation and domestic use. It uses gravity to transport water through a series of tunnels and access points, providing a reliable and sustainable water supply in arid regions.
Each input source comes into the mixer through a channel. The more channels a mixer has, the more sources it can accept.

Distant sounds may be heard due to the presence of sound waves traveling through the air or other medium from their source to your ears. The farther away a sound source is, the more it may be affected by factors like air resistance and interference, leading to it being perceived as distant.
