Successful Tenderer: Details of the procurement have not been publicly revealed. Sydney Water have indicated Diona will construct the pipeline in Cecil Hills.




Sydney Water: In June 2020, IPART approved expenditure on the project of $205 million over the pricing proposal period of FY2020-24. This was less than the $484 million of expenditure sought by Sydney Water over this period.

NSW Government: In November 2020, the 2020-21 NSW Budget indicated that Sydney Water would spend $259 million on the project in FY2020-21. It is unclear how this corresponds to IPART's final pricing determination.
