The primary purpose of catch basin inlets in stormwater sewers is to?

• A. Settle out sand and grit from the stormwater flow
• B. Prevent the dissemination of odors from the sewer
• C. Act as an equalizer of the flow to avoid overtaxing the capacity of the sewer
• D. Prevent floating objects from entering the storm sewer obstructing the flow in the sewer

Answer: (A)

The primary purpose of catch basin inlets in stormwater sewers is to settle out sand and grit from the stormwater flow. This function is critical for maintaining the effectiveness and efficiency of the stormwater management system. When stormwater flows into a catch basin, the design allows for sediments, debris, and particulate matter to settle at the bottom due to gravity. This sedimentation process helps prevent these materials from entering the larger stormwater infrastructure, such as pipes and treatment facilities, where they could cause blockages, reduce capacity, and necessitate more frequent maintenance. By intercepting and capturing sand and grit right at the entry point of the system, catch basins play a vital role in protecting the overall integrity of the stormwater management system and ensuring it operates smoothly over time. In contrast, while other options address various aspects of stormwater management and sewer system functionality, they do not align with the fundamental role of catch basins specifically focused on sediment control.
