S OURCE CONTROL ADVANTAGES �Suitable for treating stormwater from areas with significant vehicular pollution (e.g. car parks). �Can also trap litter. �Can treat stormwater from areas storing or handling petroleum products (e.g. service station and petroleum depots). �Can be retrofitted into existing drainage systems. �Minimum visual impact. LIMITATIONS �Limited removal of fine sediments or soluble pollutants. �Turbulent conditions may resuspend particles or entrain floating oil. (A high flow by-pass can overcome this problem). �Trapped debris is likely to have a high concentration of pollutants, possibly toxic. �Requires regular cleaning to achieve design objectives. �Can pose a potential safety hazard for maintenance personnel.
