Litter Basket Key Features

Litter Basket Key Features
Key Features	Benefits
Hydraulics	Minimal head/hydraulics loss Does not affect stormwater inlet capacity Treats 100% of incoming flow
Pollutant Capture and Retention	Unique by-pass overflow eliminates flooding risk More than 100% of solid pollutants >600µm Significant amounts of sediment and more than 40% TSS No remobilisation of captured pollutants
Design	Different sizes of filter media available for targeted pollutant capture Able to be retro-fitted into existing pits or supplied in its own pit Easily installed
Cleaning and Maintenance	Dry storage of pollution thereby reducing the risk of toxic fermentation Pollutants not handled during cleaning
Environmental Impact	Re-usable filter liner is easily removed for manual cleaning Reduces sedimentation build-up Visually unobtrusive

Litter Basket Pollutant Capture Efficiency Statistics

Figures quoted are mean collection efficiency statistics based on available product testing data. It is important to note that the water quality CE values are indicative of potential field CEs given that Ecosol^TM Litter Baskets provide physical screening and the removal of chemical constituents is therefore largely dependent on the chemical composition of the particles and the bonding of these chemical constituents to the surface of the particles.

Ecosol Litter Basket Key Dimensions - 2018

¹Holding capacities are largely determined by the existing inlet pit dimensions and the outlet pipe diameter but typically ranges from 120 - 364Kg at 100% full.
²The TFR varies dependent on the size and gradient of the outlet pipe and the percentage of fill for the individual baskets. For the purpose of providing indicative TFRs we have assumed a minimum 375mm diameter outlet and empty litter baskets.
³All Ecosol Litter Baskets installed in pits larger than 600mm in width are fitted with two by-pass mechanisms. Pits equal to our less than 600mm in width including all circular pit configurations are fitted with a single by-pass mechanism only.
