Abstract

Flow-weighted stormwater sampling is typically performed by large passive sampling devices or by automatic sampling equipment. While effective these systems often require significant effort to deploy and automatic samplers in particular can be expensive preventing widespread deployment over a catchment. This study aims to develop a proof of concept prototype sampling device capable of being installed in urban pit drains. The device is to be small and simple enough for widespread deployment over urban environments to allow for the detection of localized water pollution hazards.

A compact flow splitting sampling device is designed and a prototype constructed for the purpose of performance testing under controlled conditions. The device performs well proving to be capable of flow splitting accuracy in the order of 3%. The stormwater sampling device is also tested for other performance characteristics. A subsystem of the device is capable of indicating the duration of a flow event accurate to around 2%. The device also proves to be adequately capable of protecting samples from contamination and sampling suspended solids.

The sampling device developed ultimately proves to be capable of satisfactory collection of flow-weighted stormwater samples. Design details for the device along with recommended future modifications are presented. It is expected that future work would see the device tested in the field to evaluate infield performance and reliability.
