A wide trench drain typically refers to a linear drainage system designed to manage surface water runoff. The designation of 6% typically indicates the slope or gradient of the drain, which is vital for ensuring efficient water flow and preventing flooding. The wide design allows for a greater volume of water to be channelled away quickly, making it ideal for areas prone to heavy rainfall or runoff.
