​​​​​​​​TasWater is required to prepare and submit an annual performance report by 30 September each year, in accordance with the Regulator's Tasmanian Water and Sewerage Industry Performance and Information Reporting Guideline. Data from the annual performance report is included in the Regulator's State of the Industry Report. 

​​​​Annual Performance Reports 2023-24 and 2024-25

The Regulator has published these Reports, despite being unable to resolve with TasWater an issue regarding TasWater's reporting of its customer satisfaction score (Indicator CSC17). 

Under the methodology proposed by TasWater in its Price and Service Plan for the fourth regulatory period and approved by the Regulator, customer satisfaction has been measured at ​60.9 per cent in 2022-23, 56.6 per cent in 2023-24, and 65.0 per cent in 2024-25, compared to performance targets of 70.0 per cent, 72.0 per cent, and 74.0 per cent respectively.

In the Reports, TasWater has modified its customer satisfaction scores to approximate scores that may have been achieved under the methodology that TasWater applied prior to 2022-23. The Regulator has not endorsed TasWater's departure from the approved methodology.
