SCA Water Balance
The Sydney Catchment Authority's (SCA) Operating Licence condition 6.4.2 requires the SCA to provide information to the Independent Pricing and Regulatory Tribunal (IPART) by 1 September each year for the previous financial year on the water balance. It also requires the SCA to make this information available to the public.
The water balance for the individual water supply systems listed below and the total system uses the methodology developed by Sinclair Knight Merz for IPART.
- Warragamba
- Woronora
- Blue Mountains
- Shoalhaven
- Upper Nepean
Sources of Water refer to water entering each system during the year, including inflows. Distribution of Water describes water leaving the system including extractions, environmental flows, releases and spills.
