Notes
SA Water reported a $64 million upgrade of Bolivar WWTP underway in 2022, but this appears to be a brownfield upgrade rather than original greenfield construction. SA Water also reported a $15.1 million Bolivar WWTP capacity growth upgrade in 2024-25. No plant-specific original commissioning capex for the BOLIVAR1 biogas reciprocating engines was found in the searched sources, so capex_total_aud is based on the reported upgrade figure only and should be reviewed if a true original build cost is required.
