A French drain [1] (also known by other names including trench drain, blind drain, [1] rubble drain, [1] and rock drain [1]) is a trench filled with gravel or rock, or both, with or without a perforated pipe that redirects surface water and groundwater away from an area.
A percolation trench is similar to a dry well, which is typically an excavated hole filled with gravel. [3] Another similar drainage structure is a French drain, which directs water away from a building foundation, but is usually not designed to protect water quality.

[1] A slot drain is a modified trench drain. "Slot" describes its appearance on the ground.
Traditionally, land drains were formed in clay soils and peats by excavating a trench and forming a "tunnel" using flat stones. This was very labour-intensive but could often be done using free materials at hand. Typically they were two to three feet (600mm-900mm) below the surface.
Invert level affects flow from drainage pipes In civil engineering , the invert level is the base interior level of a pipe, trench or tunnel ; it can be considered the "floor" level. [ 1 ] The invert is an important datum for determining the functioning or flowline of a piping system.
