2.0 Ecosol™ Litter Basket Credentials

Ecosol has commissioned a range of tests to confirm not only product performance
but also to help with further research and development work. In 1996, the
University of South Australia, a National Australian Testing Authority (NATA)-approved
testing body, tested the Ecosol™ Litter Basket. Its full-size Roadway Surface
Drainage Rig was used to carry out a series of tests in two stages on the Ecosol™
Litter Basket. These tests measured the capture performance of the unit in both
on-grade and sag situations for a range of flows containing full-size, real-life solid
pollutants. The testing confirmed the unit’s ability to capture 97% of pollutants
greater than the filtration mesh size.

The testing also focused on determining whether the unit had any hydraulic impact
on the flows entering the pit. It found that the Ecosol™ Litter Basket did not
reduce the pit’s inlet capacity, a key benefit, especially as the unit is often installed
in road side entry pits where any level of flooding would be unacceptable. The
Ecosol™ Litter Basket also has a by-pass overflow that effectively eliminates the
risk of flooding.

In 2012 Ecosol engaged the University of Adelaide (ENGTEST The school of civil,
environmental and mining engineering) to undertake further independently laboratory
hydraulic and capture efficiency testing on the improved Ecosol™ Litter Basket design.
Additional they also undertook a comprehensive peer review of all prior and current
Ecosol™ Litter Basket field and laboratory testing reports to comprehensively
determine its performance specification. Reference – “Performance Review of
the Ecosol™ Litter Basket at- source solid pollutant filter (report dated 9 May 2013).
