Jun 2020 IPART approved expenditure on the project of $205 million, over the pricing proposal period of FY2020-24, for the components of the project which addressed growth challenges. Expenditure for the purposes of resilience, estimated to cost $280 million, would be deferred.
Nov 2020 The 2020-21 NSW Budget indicated that Sydney Water would spend $259 million on the project in FY2020-21 out of a total estimated cost of $578 million. It is unclear how this corresponds to IPART's final pricing determination.
