What component is often required when installing a drainage system to ensure proper flow?

The correct component often required when installing a drainage system to ensure proper flow is a catch basin. A catch basin acts as a collection point for surface water and helps to direct this water into the drainage system, preventing flooding and allowing for proper flow management. By capturing debris and sediment, catch basins also play a vital role in maintaining the functionality and efficiency of the drainage system, as they prevent clogs and facilitate the smooth movement of water along the drainage pathway.

Additionally, the proper installation of a catch basin can significantly reduce the risk of water pooling and promote effective drainage in various environments, making it an essential feature in any drainage system design.
