Stormwater — Quality Improvement Device — Existing

This dataset is available on Brisbane City Council’s open data website – data.brisbane.qld.gov.au. The site provides additional features for viewing and interacting with the data and for downloading the data in various formats.
This information provides a graphical representation of the locations of the existing (as constructed) stormwater quality improvement devices (SQID) in the Brisbane City Council local government area. It can be combined with other Stormwater data to provide the entire Stormwater Network. Not all assets within the network are owned, and maintained by Brisbane City Council. A Stormwater Quality Improvement Device or SQID is a device used to prevent polluting materials being transported in stormwater. There are four main types of SQID: Filter, Gross Pollution Trap (GPT), Trash Rack and Wetland. A filter is used to block finer particles and sediments. A GPT is used to block debris typically larger than 3mm. A Trash Rack is a series of metal vertical and/or horizontal metal bars positioned across a drainage channel and designed to intercept litter and debris. A wetland is a naturally occurring area inundated or saturated by surface or groundwater and capable of sustaining vegetation typically adapted for life in such conditions.
