Drainage tile refers to a type of underground irrigation system used to manage excess water in fields, gardens, and other outdoor spaces. There are several synonyms for drainage tile, including drain tile, drain pipe, and French drain. Drain tile and drain pipe both refer to the same type of drainage system that utilizes perforated pipes placed underground to collect and redirect excess water away from the surface. French drain, on the other hand, is a slightly different type of drainage system that uses a trench filled with gravel and a perforated pipe to redirect water away from an area. Regardless of the terminology used, drainage tiles play a critical role in maintaining healthy outdoor environments.
