Stormwater Australia is the custodian of an industry-formulated, independent evaluation process for verifying the performance of technologies for improving stormwater quality.


Field Testing

SQIDEP provides a uniform set of criteria to which stormwater treatment measures can be field-tested and reported. These criteria should guide and inform field monitoring programs seeking to demonstrate pollutant removals for stormwater treatment measures included in pollutant export modelling software.

Future revisions of the protocol are anticipated to also include laboratory testing.

SQIDEP should be recognised to be a living document. 



Two pathways are available for evaluation under the SQIDEP process:

  1. The first is the Body of Evidence pathway for those submitters that commenced Australian field testing prior to the release of Version 1.3, 3rd January 2019. One Submission Form is required for the BoE pathway.
  2. The second pathway is the Field Evaluation pathway. Two separate Submission Forms are required for the Field Evaluation Pathway;
    1. Stage One: The submission of a Quality Assurance Project Plan (QAPP) for approval prior to commencing field testing; and
    2. Stage Two: Submission for a Detailed Performance Report (DPR) upon completion of field testing.

Please refer to the pdfSQIDEP Evaluation Process Chart for each application/submission, and the SQIDEP Governance Framework for more information.

When a submission is successfully verified by either the BoE pathway or Stage Two of the Field Evaluation pathway, a Verification Certificate will be issued (pdfExample) and will be published to the SQIDEP Verified Products webpage, along with the final Verification Report from the Independent Evaluators.


Submission Forms
