GD03: Proprietary Devices Evaluation Protocol (PDEP)

Draft version 1 - November 2011

TP10 (2003) chapter 15 provides guidance on how to evaluate storm water treatment devices not included in TP10.  GD03 Proprietary Device Evaluation Protocol (PDEP) is intended to detail the evaluation of device performance, and will supercede Chapter 15 of TP10 (2003).  This new guideline aims to provide a transparent, consistent and timely approach to the evaluation of the performance of proprietary stormwater management devices in the Auckland region.

This document consists of the following parts:

  • Brief description of the Evaluation Process and Flow Chart
  • Evaluation Process and its requirement at each stage
  • Evaluation Criteria – Performance & Operation
  • Field Evaluation requirements
  • Performance Reporting requirements

The process is initiated by the vendor submitting a Performance Claim, supported by documented evidence.  Council will verify and certify whether the device meets the claim.  The evaluation process can proceed via the Body of Evidence (BoE) route, where evidence which meets the minimum requirement of BoE (Table 2) is supplied from trials carried out locally or internationally.  Alternatively, the device can be verified through the Local Pilot Trial (LPT) route.  As the name suggests, the verification by LPT will be carried out based on local pilot trial/s on a selected site and/or sites.
