Every TasWater drinking water system met full microbiological compliance last financial year and none went on a boil water alert, the Tasmanian economic regulator says.
The regulator released its annual report on the state’s water and sewerage industry this week, covering TasWater’s performance for 2024-25.
The utility also cut the amount of water it loses before it reaches customers, with unaccounted-for water falling from 29.2% in 2021-22 to 21.4% in 2024-25.
TasWater wants to push that down further, to 20% next financial year and 18.5% by 2028-29.
Economic Regulator Joe Dimasi said the results showed steady progress.
“The results for 2024-25 highlight TasWater’s ongoing and improving performance in meeting its targets,” he said.
Dimasi said the utility’s drinking water quality “remains high”, reflecting its “ongoing investment in treatment upgrades and risk management”.
But he said there was still a long way to go.
“TasWater still has significant work to do to improve its performance,” Dimasi said.
That work is backed by $1.2 billion in capital investment approved over the next four years.
The report stated TasWater missed its minimum service standards for water main breaks, sewer breaks and chokes and unplanned interruptions.
Its performance on those measures also fell short of similar-sized mainland utilities.
More than 52,000 customers were affected by unplanned interruptions during the year.
Water main breaks, sewer breaks and unplanned interruptions all dropped from the year before. Interruptions fell about 28%.
Prices went up 3.5% in 2024-25, lifting the typical annual household bill to $1,370.60.
The report states the number of residential customers repaying a debt rose 9.4% to 4,500. The average debt climbed 8.5% to $1,641.
TasWater posted an underlying profit of $39.0 million, up from $32.6 million.
