TasWater says it will invest about A$1.2 billion in water and sewerage infrastructure over 2026–2030 and defer about A$500 million of capital works, after the Tasmanian Economic Regulator approved a smaller program than it asked for. The utility set out the figures on 24 September 2026.
What the Regulator approved
TasWater proposed A$1,673.5 million of capital expenditure for 1 July 2026 to 30 June 2030. The Regulator's determination of 30 April 2026 allowed A$1,175.1 million, and a revenue allowance of A$1,950.9 million against A$2,252.4 million proposed. Average prices may rise 5.7% a year; the Regulator put TasWater's proposal at 11.5% a year. It also did not accept TasWater's proposal to defer A$127.5 million of revenue to the next period.
Where the cuts fall
Growth investment falls by nearly two-thirds, from A$98.2 million to A$35.5 million over the four years to 2030, as part of the roughly A$500 million deferral. The individual deferred projects have not been named. The Regulator's capital reviewer had already assumed lower amounts for the biggest items: A$213 million for the Ti Tree Bend transformation in Launceston against A$356 million proposed, and A$75 million for Ridgeway Dam in Hobart against A$143.8 million.
A second claim on revenue
Prices became contentious soon after they took effect on 1 July 2026. On 10 September 2026 the Premier asked TasWater and councils to pause the increases, and from 2 October TasWater paused some non-residential sewerage bills. It has said the cost will not be passed to other customers and could require deferral of further infrastructure investment. Net debt to equity had already risen from 45.4% in FY 2023-24 to 56.3% in FY 2024-25.
