The catch basin data is collected by SFDPW Hydraulics Engineering and SFPUC Wastewater Enterprise, Collection System Division engineers, drafters and operators. The data is collected from sewer reference and construction documents and field surveys. You can learn more about how the City's wastewater collection system works here: http://www.sfwater.org/index.aspx?page=399

This dataset details the location and attributes of drainage lines throughout the City of Joondalup

Stormwater Network at City of Port Adelaide Enfield. 4 map layers comprising of Conduits, Connectors and Wetlands. This data is presented through the Council's own website for open geospatial data. Formats available are SHP, KML, GeoJson and WMS. (all in geographic latitude and longitude except the Shapefile which is GDA 1994 MGA Zone 54)

The data being collected is to be used for several purposes: - Hydraulic/hydrologic modeling input - Work Order Management System integration - Map book production - Mobile redlining/correction submission tools

This dataset details the location and attributes of drainage nodes throughout the City of Joondalup.

This dataset provides the locations of Swale Drains for community users within the City of Casey, extracted from the City of Casey's Asset Management System and GIS databases.

Polyline geospatial data of Drain Pipes for the City of Greater Geelong. All storm water drains pipes are listed. >*Although all due care has been taken to ensure that these data are correct, no warranty is expressed or implied by the City of Greater Geelong in their use.*

Stormwater, wastewater, and drinking water data from a variety of sources is being compiled. Stormwater data has (is) been collected for many urbanized town and village centers statewide. Wastewater data is available for some towns and is currently being developed more fully as data becomes available. Drinking water data is rarely available. Point, line, and polygon data was collected and compiled through field observations, municipal member knowledge, ortho-photo interpretation, digitization of georeferenced town plans and record drawings, and state stormwater permit plans. Accuracy of all data is for planning purposes and field verification is at the users discretion. Subwatershed Drainage systems were mapped to establish the connectivity of the stormwater features, and to show where runoff from impervious surfaces in various subwatersheds within an urbanized area eventually enters the receiving water. Subwatershed boundaries were drawn by hand using a variety of elevation data and corelated to each towns Stormwater Infrastructure report.
