/  Drainage

A system for channeling surface water or subsurface water into sewers, wherein the drainage system must be able to separate soil, sand or rock material so that it does not come with the water. In order to contain other materials that are involved in the drain, a geotextile is required to contain the material, but not to prevent water from escaping.

Application: Drainage pipes in golf greens and bunkers, railroads or ball fields, etc
