![]() Which catch basin type is most appropriate for the site’s geography?.What are the stormwater management goals (in terms of water volume) for the site?.Answers to these questions will help you select the catch basin for your project: The availability of precast catch basins makes it easy to customize dimensions to meet specific site conditions. Determining Which Type of Precast Catch Basin to UseĬatch basins have been designed in several sizes and structures to meet the wide variety of needs for managing runoff. ![]() The precast catch basin helps prevent downstream sewer pipes from clogging and reduces the amount of solid material discharged into lakes, streams, and rivers. Debris is cleared by hand or a Vactor catch basin cleaning truck. The basin grate filters large pieces of debris, while its sump collects sediment, oils, grease and smaller material like leaves and litter found in stormwater runoff. Unlike manholes or grated inlets, catch basins include a sump, or hollow, at the bottom. You’ll find them in parking lots, on street curbs or in maintenance yards – just about any location where rainwater travels from a hard surface into the system. ![]() Importance of a Precast Catch BasinĬatch basins are concrete grated entryways to storm drainage systems. These hard surfaces can’t absorb stormwater and some areas would quickly become large, debris-filled lakes without the capabilities of a precast catch basin. The purpose of precast catch basins has evolved to fit today’s concrete and asphalt landscapes. Ancient civilizations created catch basins to hold seasonal rainwater, ensuring crops could be irrigated until harvest. ![]()
