When do bar or wire-mesh screens usually encounter the largest amount of debris?

• A. Beginning Of Spring
• B. During Spring
• C. Autumn
• D. Winter

Answer: (C)

Autumn is when debris loading on bar and wire-mmesh screens is greatest because deciduous trees shed a large amount of leaves, twigs, and seeds during the fall. That plant litter is carried by wind and water into water intakes, accumulating on the screens and causing more frequent clogging. While spring runoff can bring some debris, by autumn much of the litter has just fallen, making the debris load peak then. Knowing this helps schedule cleaning and maintenance to prevent screen clogging, typically by prioritizing autumn inspections and cleaning.
