Channel drains, also called trench drains, are long, narrow drains used for surface drainage of hardscapes. As part of a complete drainage system, channel drains collect and convey water to drain pipes, which carry the water downstream to discharge with a pop-up emitter or to percolate into the ground with a dry well or infiltration trench. NDS channel and trench drains are designed for durability, drainage and performance and are a proven alternative to traditional concrete drains.
