Sydney Water is a state-owned corporation that provide services and infrastructure for potable water provision, wastewater and drainage (stormwater) management in the greater Sydney region including the Blue Mountains and Illawarra in New South Wales, Australia. It is not to be confused with WaterNSW, which provides the raw bulk water supply to Sydney Water and jointly operate certain assets.

Asset identification

Most assets are easily identifiable even if they are located on private property thanks to good signage installed on most assets by Sydney Water since 2017 or so.

WS Water Water storage facility, reservoir or surge tank; generally a covered reservoir or elevated water tower. area osm:way/854921268
Bullaburra reservoir
WP Water Pumping station for potable water. Sometimes coded "WPS" especially for assets managed by WaterNSW.

Sometimes it is a cabinet but it can also be a building or industrial area.

Water Pumping Station servicing Blackheath Reservoir enclosed in a cabinet in Blackheath, NSW
WT Water Water treatment plant or filtration plant. Either tag the campus or alternatively just the building if there are multiple separate facilities on the Sydney Water lot. area osm:way/53842171
WX Water Water chemical dosing, eg. chlorination and fluoridation. Typically a building. area osm:way/846644097
A water chlorination plant servicing Wentworth Falls Reservoir
SP Sewerage Pumping station for wastewater (sewerage). Sometimes coded "SPS". Usually a white or brown/green cabinet.

SP sites usually have floodlighting, manholes and ventilation masts. Sometimes a street signpost will identify the site if it is at the end of a driveway. If the pumping station is located inside a building, consider putting the tags on a building=service.

  • For consistency, asset numbers should be given 4 digits including leading zeros, and no spaces.
  • IICATS (Integrated Instrumentation, Control, Automation and Telemetry System) refers to remote monitoring system similar to SCADA.

Sewage Network

Northern Suburbs Ocean Outfall Sewer (NSOOS)

relation Northern Suburbs Ocean Outfall Sewer

The following considerations were given when selecting tags for the NSOOS.

Per Key:waterway#Values when considering free flow vs pipe flow given the sewer line is gravity fed, not pressurised and would usually contain a free surface (the ceiling) where air is present we consider it free flow. Therefore according to Key:waterway#Values it is not man_made=pipeline and must therefore be a waterway=*.

waterway=* is broken down into natural watercourses and artificial waterways, since this is an artificial waterway, we considered waterway=drain which is documented as “An artificial free flow waterway used for carrying superfluous water like storm water or industrial discharge, usually lined with concrete, stones or similar.”

The NSOOS is artificial, free flow, carries superfluous water and lined with concrete and therefore waterway=drain has been selected as the waterway tag value.

For the tunnel sections tunnel=flooded is appropriate, for the aqueduct sections bridge=aqueduct is appropriate.

usage=transmission is selected as the sewage is carried a long distance and is a main transmission line.

The location=* tag should also be used, the tunnel sections should have location=underground and aqueduct sections should have location=overhead.
