Dataset Number 1030 Dataset Title Stormwater Drains Custodian Data Authority: Department for Environment and Water Data Provider: Department for Environment and Water

Description Description Stormwater pipe infrastructure and open drainage network, collected by 19 Local Councils and compiled INTO a single, contiguous dataset. Flow direction has been incorporated INTO the dataset, however some flow directions may be incorrect. The dataset is under continual update as Councils collect and upgrade infrastructure. Usage The dataset can be used to show the extent of the stormwater network. Attributes of size, slope, type etc are included where known for analysis in flood modelling and pollution studies.

Data Quality Lineage The Stormwater Drains dataset has been derived by updating the 2005 dataset with data obtained from Local Government Councils. See document: Report INTO the Capture of Urban Stormwater For the Onkaparinga and Torrens Catchment Water Management Boards (Verhoef and Cundell, 2003) Completeness The stormwater dataset is incomplete. Updates and new data are added to the dataset on a yearly basis, as councils continue to collect asset information. Positional Accuracy Differing capture methods used by councils result in varying positional accuracy within each council's subset. Assets have been captured from maps, drawings and plans at a range of scales. The "Spat_acc" attribute records positional accuracy for each item. Lookup tables in the document "Report INTO the Capture of Urban Stormwater For the Onkaparinga and Torrens Catchment Water Management Boards (Verhoef and Cundell, 2003)" interpret attribute values INTO 3 classes. The "Cap_meth" attribute records method of capture for each record. Line matching across some council boundaries is incomplete.
