During 2009–10, Sydney’s desalination plant at Kurnell supplied 19,952 ML to the Sydney Water Corporation’s (SWC) urban water distribution system. In order to produce this volume, an estimated volume of 67,061 ML of sea water was drawn. The residual hypersaline concentrate (approximately 47,109 ML) was returned to the sea.
Data are managed and maintained in an internal data management system by the Sydney Water Corporation’s (SWC) Operations Division (Hydraulic Systems Services).

The volume was derived from flow meter data on the outflow of desalinated water from the plant.
The flow meter data are continually monitored and recorded. Flow meters are maintained and calibrated according to meter manufacturers’ specifications. The data are stored within a complex data management system. Adjustments are made to the data (if necessary) to correct any interruptions, errors and so on. Data have been extracted for 2009–10 from the data management system.
The volume is based on measured data. Estimated uncertainty based on meter accuracy is +/–2%.
