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.

Since the majority of the sewer is underground it is difficult to survey and map, however from around 2017 though to 2025 and onwards a revitalisation project has been underway to perform once in a century maintenance and restoration of the sewer, as a result key access points of the sewer network have become surveyable due when maintenance works are being undertaken.

Tagging information can be found at Sydney Water#Northern Suburbs Ocean Outfall Sewer (NSOOS).
