Evaluation of Gully Pit Inlet Litter Control Systems– Brisbane City Council and Gold Coast City Council
1% grade:
• All litter was collected and retained up to an approach flow of
100L/sec for both collection baskets.
• Approximately 15% of the litter had bypassed the unit at 200L/sec
due to resuspension.
• The finer mesh basket retained 70% of litter after an approach flow of
320 L/sec and the coarse basket retained 65%.
• The mesh in both baskets became blocked after a flow of 320 L/sec
and held water for a short period after flow was stopped.
• As the flow dropped from 320L/sec to below 50L/sec some of the
pollutants attached to the fabric dislodged from the sides. The low
flow effectively washed the litter off the basket sides (see Figure 7).
