4.3.2 Assessment of Results

The developed site has been modelled as a series of commercial sub-catchments, which
incorporate Water Sensitive Urban Design (WSUD) treatment trains. Plan No 1714-01 shows
the proposed locations of the rainwater tanks; detention systems and biopods. The reductions
listed in Section 4.3.1 above generally comply with Council’s requirements.

The percentage reductions for Total Suspended Solids and Total Phosphorus are slightly below
the target figures, by 0.2% and 0.4% respectively. These amounts are considered within error
range and therefore, it is considered that the proposed stormwater treatment system is
sufficient to reduce the pollutants prior to exiting the site.
