All grated inlet pits within the driveway are to be fitted with Ecosol Litter baskets with 1500µm filter Bags. 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 106L/s per pit and concentration-based capture efficiency set in accordance with manufacturers
guidelines. Refer to Appendix D Ecosol Litter Basket Technical Specification for further details on the devices.
