Catch basins are available in various sizes to capture low, moderate, and high water flows for a range of applications such as for lawns, landscaped areas, patios, walkways, under downspouts, driveways, parks, and courtyards. As part of a complete drainage system, the catch basin drain directs water to connected drain pipe, which carry the water to a discharge point downstream such as a pop-up emitter or to percolate into the ground with a dry well or infiltration trench.
