The Independent Pricing and Regulatory Tribunal of New South Wales (the Tribunal) determines the maximum prices that Sydney Water Corporation (SWC) can levy for its water, sewerage and drainage services.

In July 1999, the Government established the Sydney Catchment Authority (SCA). The SCA is responsible for supplying bulk water and for managing and protecting the catchments utilised for the harvesting and storage of bulk water. These functions were previously undertaken by SWC. The Tribunal has responsibility for determining prices for SCA for five years from 1 October 2000.
