Sippy Downs SPEL Basin
A SPEL Basin was submitted for evaluation against the SQIDEP protocol in October, 2019.
Testing for the system was conducted over the period from March 2017 to April 2018 by the
University of Sunshine Coast (USC), with the testing criteria adapted to meet the SQIDEP
Protocol (released subsequent to the testing period). USC is an independent organisation
that undertook the testing on a fee for service basis.

The basin installation is on Sippy Downs Drive, Sippy Downs and can be seen in Figure 1.
Greater description is contained in review documents 1 and 2.

A review of the site and catchment conditions is shown below. The field monitoring claims to
have met all of the criteria of the SQIDEP protocol, and this claim is evaluated in this report.
