Greater Sydney storage trigger

Greater Sydney storage trigger

As of 19 August 2019, Greater Sydney reached 50.0% total storage levels. As part of the NSW Government’s 2017 Metropolitan Water Plan (PDF), a range of measures are in place to manage Sydney’s water supply in drought.

Total storage levels in Greater Sydney reached 59.9% on 27 January 2019.  Once total storage levels fall below 60% the Sydney Desalination Plant (SDP) is notified to start and is now at full capacity. Desalinated water will help meet customer demands as the drought intensifies. Sydney’s water supply is otherwise entirely dependent on rainfall.

Unlike many regional catchments facing drought, Sydney has around two years of water supply remaining – even with zero inflows. Sydney typically receives annual rainfall exceeding 1200mm.

WaterNSW will continue to provide regular updates on Greater Sydney’s storage levels.
