The ability of a drainage system to avoid clogging is known as?

The correct answer is identified as drainage capacity, which refers to the effectiveness of a drainage system in handling and transporting water and waste without becoming blocked or obstructed. A system with good drainage capacity can facilitate the smooth flow of liquids through pipes, ensuring that the design can handle the volumes and flow rates expected during operation.

This term indicates how well the system can accommodate various conditions, such as peak usage times, without experiencing clogging issues. Proper drainage capacity is essential for preventing backups and ensuring that the system operates efficiently, maintaining hygiene and preventing potential damage to properties.

The other terms, while related, do not specifically define the ability to avoid clogging in the way drainage capacity does. For example, flow capacity generally refers to the maximum flow rate a system can handle but doesn't specifically deal with how well that flow is maintained without blockages. Drainage efficiency focuses on how effectively the system operates relative to its design, which may not solely depend on the ability to avoid clogging. Capacity tolerance might imply the limits of what the system can withstand without failure but does not directly define the mechanism preventing clogs. Therefore, drainage capacity is the most accurate term to describe the ability of a drainage system to avoid clogging.
