Results also indicate that average annual runoff under the developed scenario with rainwater reuse is only 0.09 ML
(1.2%) lower than under the existing scenarios. Therefore, the developed site is closely replicating runoff volumes of
the existing site.

The water balance analysis undertaken shows that the proposed development with reuse measures produces
average annual runoff volumes lower than existing volumes. Therefore the Noosa Council requirement for
maintenance of existing site average annual runoff volumes by the proposed development is complied with.
