Further to proposed job cuts in the south, the Australian Services Union understands TasWater's taking the axe to around 30 positions in the West and Northwest.
Reportedly four of 15 roles are under consideration for being wound up on the West Coast.
Labor leader Bryan Green told Tasmania Talks, the jobs have to be saved, especially with all the work facing TasWater to repair the state's under par water and sewerage infrastructure.
"What they should be looking at is making sure they maintain that employment and I think that local government who are the owners should be insisting that they maintain that employment and getting ready for the projects that er going to be taken on."
In a state that still has 25 locations boil water alerts and a swerage spill rate 7 times the national average, the Tasmanian government's decided it will take control of TasWater from councils to enable a faster rollout of infrastrure work.
