The Proprietary Device Evaluation Protocol for Stormwater Treatment in the Auckland Region

Today, an ever growing selection of proprietary stormwater treatment devices are available to meet these and other challenges associated with stormwater management. However, the performance of many of these devices is not well documented. To aid in the evaluation of the performance of proprietary stormwater treatment devices, the Auckland Council has developed a stand alone assessment protocol. The Proprietary Device Evaluation Protocol (PDEP) was developed to streamline and make transparent the Auckland Council evaluation. Under PDEP, the manufacturer or vendor can make a claim based on the device’s treatment performance, with relevant effectiveness assessment data and documentation. The Auckland Council then reviews application to determine if it substantiates the claim the manufacturer has made and certifies the performance claim. This paper provides an overview of PDEP, the evaluation process, and the information required to undertake the evaluation.
