This database summarises the water quality of urban run-off events across Australia based on monitoring conducted by the CRC for Water Sensitive Cities in collaboration with the Urban Water Security Alliance. It provides the largest single database for Australian stormwater quality to date with the broadest range of water quality parameters measured within one study.

The database summarises event mean concentrations of 94 samples taken from a total of ten different catchments across four states of Australia, i.e. New South Wales (n=21), Queensland (n=41) and Western Australia (n=6; these samples were collected as grab samples during rain events).
