Sport field trench drain applications are often simple and straight forward. There are four very common applications for trench drains in sporting areas. The first is channel drain around the inside of a track to ensure that no water stands next to the track surface. Standing water near the track surface causes a delamination of the costly track surface. The second most common application for a trench drain is along one edge of a court to allow for a simple grading of the court. This is common on basketball and tennis courts to ensure a level court and no ponding on the playing surface. The third most common application for trench drain is behind the back stop at baseball and softball fields. A trench drain allows the playing field to have a simple grade and keeps the playing field dry during rain events. The fourth common application for trench drains is in the stadium and bleacher area. A trench drain at the bottom of the bleachers keeps the water from running down into the sporting area while keeping pedestrian areas flat and level. This is often seen in football, soccer, lacrosse, and field hockey stadiums.
