    en.wikipedia.org/wiki/Communicating_vessels

    Since the days of ancient Rome, the concept of communicating vessels has been used for indoor plumbing, via aquifers and lead pipes. Water will reach the same level in all parts of the system, which acts as communicating vessels, regardless of what the lowest point is of the pipes – although in practical terms the lowest point of the system depends on the ability of the plumbing to withstand ...

    en.wikipedia.org/wiki/Tremie

    The tremie concrete placement method uses a vertical or nearly vertical pipe, through which concrete is placed by gravity feed below water level. [4]The lower end of the pipe is kept immersed in fresh concrete so that concrete rising from the bottom displaces the water above it, thus limiting washing out of the cement content of the fresh concrete at the exposed upper surface.

    PCCP is typical manufactured according to the American Water Works Association (AWWA) standard C304. [1] PCCP is a composite structure that is composed of a concrete core, high-tensile prestressed steel wires, a thin steel cylinder, and mortar coating. [2] It is widely used globally in water systems infrastructure. [3]
