Grated inlet pits within the driveway are to be fitted with Ecosol Litter baskets with 200µm filter bags or approved
equivalent. These have been certified by the manufacturer as having the pollutant removal efficiencies shown in
Figure 4.4 - Ecosol Litter Basket Pollutant Removal Efficiencies. The inserts are modelled using generic treatment
nodes, with a high flow bypass of 53L/s per pit (4 pits have been modelled within the driveway area, with total
bypass of 212L/s) and concentration-based capture efficiency set in accordance with manufacturers guidelines.
Refer to Appendix Ecosol Litter Basket Technical Specifications for further details on the devices and it’s MUSIC
