Pre-cast trench drains generally come in 4-inch (100 mm) widths but can range anywhere from a 1.75-inch (44 mm) slot to 2-inch (51 mm) wide channels with grates, and up to any size imaginable through custom trench drain divisions.
A diagram of a traditional French drain. 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.

Trenchers may range in size from walk-behind models, to attachments for a skid loader or tractor, to very heavy tracked heavy equipment.
A pipe laser, or another vertical distance measuring device is most commonly used for this. Invert levels are important for the drainage of a non-pressured fluid pipe. Typically, a good design requires that the invert level of the pipe will be lower (or at least not higher) for each section of pipe before it reaches its final destination. [5]
Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...
A utility tunnel, utility corridor, or utilidor is a passage built underground or above ground to carry utility lines such as electricity, steam, water supply pipes, and sewer pipes. Communications utilities like fiber optics, cable television, and telephone cables are also sometimes carried.
A main component of the base section is a channel that provides a smooth conduit for wastewater to flow from inlet pipe to outlet pipe. The channel is in a U shape formed by a "half pipe" as if a pipe is cut in half and left with the bottom half. The width of the channel should match the inside diameter of the inlet and outlet pipes.
According to the International Residential Code 2003, an air gap length must meet the requirements of being two times the effective inner diameter of the pipe (2×D) in order to be sufficient.
